Section-wise analysis:

Polity

  • This section's questions were simple to moderate. Many simple questions, such as deputy speaker, constitutional amendment bill, anti-defection statute, and so on, may be solved easily if your notions are clear. However, it also included several moderate but manageable concepts, such as those about attorneys and contempt of court. Surprisingly, compared to previous years, the number of questions from this section has decreased dramatically this year.

Environment

  • Many climate organisations' questions, such as Climate Action Tracker, Climate Group, and EP100, have been asked by UPSC. Questions on the System of Rice Intensification and particle matter were also posed in the agricultural section. The questions in this part were less disputed and plainer than in prior years.

Geography

  • Some questions were possible to answer, while others were not. Because the questions were direct, several of them fell into the “either you know or you don't” category.

Current affair

  • Questions from this section saw an upward trend. Much of the questions from this section were from the technology section and geographical location section.

Economy

  • It's a little tougher this year than it was last year. Around 20 questions were conceptual in nature. This year, questions on NEER, REER, inflation-indexed bonds, debt financing, and other topics were difficult to answer.

S&T

  • This section's questions were challenging. This year, there were also concerns about new and upcoming technology. Questions were posed on SaaS, qubit, Web 3.0, and other related subjects. Aspirants should not expect to learn about every technical innovation, especially in such detail. In order to answer these questions, you'll need to use a good elimination approach.

History

  • Same as usual, History was another focus area where the focus was on Buddhism, Jainism, Temples, literature and Texts, Mongols, Early British Expansion, constitutional history, Revolutionaries, Sangam Literature, Mauryan Dynasty. Some of the questions can be termed difficult to answer.

*** No question on awards, do not change ur strategy ***
***new form of options emerged this year that asked the aspirants to mark the current pairs***
(* Interestingly, the scope of using elimination techniques was limited due to a new pattern of options. E.g. previously, the candidates had the chance of arriving at an answer by eliminating one or two options).

The writ can be issued only in case of a substantive public office of a permanent character created by a statute or by the Constitution. It cannot be issued in cases of ministerial office or private office. Unlike the other four writs, this can be sought by any interested person and not necessarily by the aggrieved person.

Deputy Speaker of Lok Sabha 

Like the Speaker, the Deputy Speaker is also elected by the Lok Sabha itself from amongst its members. He is elected after the election of the Speaker has taken place. The date of election of the Deputy Speaker is fixed by the Speaker. Whenever the office of the Deputy Speaker falls vacant, the Lok Sabha elects another member to fill the vacancy.

Upto the 10th Lok Sabha, both the Speaker and the Deputy Speaker were usually from the ruling party. Since the 11th Lok Sabha, there has been a consensus that the Speaker comes from the ruling party (or ruling alliance) and the post of Deputy Speaker goes to the main opposition party.

The Deputy Speaker performs the duties of the Speaker’s office when it is vacant. He also acts as the Speaker when the latter is absent from the sitting of the House. In both the cases, he assumes all the powers of the Speaker. He also presides over the joint sitting of both the Houses of Parliament, in case the Speaker is absent from such a sitting.

At any time before noon on the day preceding the date so fixed, any member may give notice in writing, addressed to the Secretary-General, of a motion that another member be chosen as the Deputy Speaker of the House and the notice shall be seconded by a third member and shall be accompanied by a statement by the member whose name is proposed in the notice that the member proposed is willing to serve as Deputy Speaker

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (d)

Explanation:

System of Rice Intensification (SRI) includes a method called Alternate Wetting and Drying (AWD) which is a form of controlled or intermittent irrigation of the rice crops.  The benefits from the programme include reduction in methane emissions from traditional rice cultivation, and significant reduction in water consumption. The crop yields are maintained and not affected negatively, and the programme leads to the creation of community organisation and strengthening of networks through the formation of farmer groups. Typically, farmers use diesel to pump large amounts of water to flood their fields. With intermittent flooding, water pumps are run for shorter periods of time, reducing fuel consumption.

Benefits and Impacts of SRI 

  • To increase paddy yields usually by 20-50% and sometimes 100% or more;
  • To reduce required seeds for transplanting by 60-80%;
  • To reduce use of chemical fertilizers and agrichemicals;
  • To reduce irrigation water by 25-50%;
  • To reduce production costs usually by 10-20%; and
  • With increased output and reduced costs, farmers’ net income is increased.

In 1974, this lake covered roughly 590 square kilometers (230 square miles). Starting in the late 1980s, a drop in precipitation steadily dried the lake. By the late 1990s, the traditional livelihoods of fishing, agriculture, and livestock herding became impractical. Even though normal rainfall resumed after the year 2000, the lake remained nearly dry.

29. In the northern hemisphere, the longest day of the year normally occurs in the:

(a) First half of the month of June

(b) Second half of the month of June

(c) First half of the month of July

(d) Second half of the month of July

Correct Option: (b)

Explanation:

Explanation: summer solstice, the two moments during the year when the path of the Sun in the sky is farthest north in the Northern Hemisphere (June 20 or 21) or farthest south in the Southern Hemisphere (December 21 or 22).

At the summer solstice, the Sun travels the longest path through the sky, and that day therefore has the most daylight. When the summer solstice happens in the Northern Hemisphere, the North Pole is tilted about 23.4° (23°27´) toward the Sun. Because the Sun’s rays are shifted northward from the Equator by the same amount, the vertical noon rays are directly overhead at the Tropic of Cancer (23°27´ N). Six months later, the South Pole is inclined about 23.4° toward the Sun. On this day of the summer solstice in the Southern Hemisphere, the Sun’s vertical overhead rays progress to their southernmost position, the Tropic of Capricorn (23°27´ S).

(c) 1, 3 and 4 only

(d) 1, 2, 3 and 4

Correct Option: (d)

Explanation:

An open source platform is any platform that allows access to its source code to any other users or developers. An open source platform is one aspect of a wide availability of open source products. In contrast with closed source software, which is a type of proprietary software that reserves rights only to authorized individuals, open source software aims to allow equal access to anyone and everyone. Open source products are oftentimes part of the free software movement, and the associated Free Software Foundation founded by Richard Stallman in 1985. Rather than being concerned with the cost of the software, the free software movement, and associated foundation, aim to ensure that software users are free to run software, study the software, modify the software, and share such modifications. However, not all open source platforms are part of the free software movement, but they are almost always part of the open source software movement.

Aarogya Setu , India’s coronavirus ( COVID-19 ) contact-tracing and self-assessment app is now open source . 

DigiLocker is an initiative by the government to offer Indian citizens a free platform to store and access important documents. The platform uses several open source technologies to deliver a mass solution and contributes back to the ever-growing community.

DIKSHA is built using Sunbird ED, a fully functional solution building block available as open-source software under MIT license and is part of Sunbird, a “Made in India, Made for the World” digital public good (DPG).

Co-WIN, which is owned by the Ministry of Health and Family Welfare, was developed using open source software. This type of software allows users to modify the source code and distribute it.

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (d)

Explanation:

Web 3.0 is the next version of the internet, where services will run on blockchain. It is a decentralised internet that runs on a public blockchain, which is also used for cryptocurrency transactions.

It will be permissionless and democratic. For instance: Twitter will not be able to censor posts and Facebook will not be able to maintain a database of billions of users that can be potentially used to influence elections.

In a Web 3.0 universe, people will control their own data and will be able to move around from social media to email to shopping using a single personalized account, creating a public record on the blockchain of all of that activity.

All data will be interconnected in a decentralized way, unlike the current generation of the internet (Web 2.0), where data is mostly stored in centralized repositories. 

– Three key features of Web 3.0 are: Ubiquity, Semantic Web, Artificial Intelligence and 3D Graphics.

– Examples of Web 3.0: The most recent example of Web 3.0 are the NFTs or non-fungible tokens.

Hence , all the statements are correct.

 

33. With reference to “Software as a Service (SaaS)”, consider the following statements :

  1. SaaS buyers can customise the user interface and can change data fields.
  2. SaaS users can access their data through their mobile devices.

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (d)

Explanation:

Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365). 

SaaS provides a complete software solution which you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organisation and your users connect to it over the Internet, usually with a web browser. Statement 1 is incorrect.

Access app data from anywhere. With data stored in the cloud, users can access their information from any Internet-connected computer or mobile device. And when app data is stored in the cloud, no data is lost if a user’s computer or device fails. Statement 2 is correct.

If you have used a web-based email service such as Outlook, Hotmail or Yahoo! Mail, then you have already used a form of SaaS. With these services, you log into your account over the Internet, often from a web browser. The email software is located on the service provider’s network and your messages are stored there as well. You can access your email and stored messages from a web browser on any computer or Internet-connected device. Statement 3 is correct. 

 

34. Which one of the following statements best reflects the idea behind the “Fractional Orbital Bombardment System” often talked about in media ?

(a) A hypersonic missile is -launched into space to counter the asteroid approaching the Earth and explode it in space.

(b) A spacecraft lands on another planet after making several orbital motions.

(c) A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.

(d) A spacecraft moves along a comet with the same speed and places a probe on its surface.'

Correct Option: (c)

Explanation:

A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn.

The idea behind FOBS is, a warhead is put into a stable orbit and it deorbits over the target.

If the target and the launch position is lined up and the warhead keeps going round, it will complete a circle.Obviously, with the earth moving during this, it is more of a spiral than a ring, but the horizontal movement is countered in such a way that the warhead still goes over the target.

 

35. Which one of the following is the context in which the term “qubit” is mentioned ?

(a) Cloud Services

(b) Quantum Computing

(c) Visible Light Communication Technologies

(d) Wireless Communication Technologies

Correct Option: (b)

Explanation:

The phrase ‘quantum supremacy’ was coined in the year 2011 by John Preskill, Professor of Theoretical Physics at the California Institute of Technology.

Quantum supremacy refers to a problem-solving process by the quantum computer that cannot be solved by a classical computer in its normal lifetime.

The concept is related to the speed at which a quantum computer performs.

Quantum computers are different from binary digital electronic computers that are based on transistors (a semiconductor device used to amplify or switch electronic signals and electrical power).

The common digital computing requires the data to be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1).

Quantum computation uses quantum bits (qubits).

Quantum Bit (Qubit)

A quantum bit (qubit) is the smallest unit of quantum information, which is the quantum analog of the regular computer bit, used in the field of quantum computing.

They operate according to two key principles of quantum physics: superposition and entanglement.? Superposition means that each qubit can represent both a ‘1’ and a ‘0’ at the same time.

Entanglement means that qubits in a superposition state can be correlated with each other; that is, the state of one qubit (whether it is a 1 or a 0) can depend on the state of another qubit. It means that particles remain connected so that actions performed on one affect the other, even when separated by great distances. The phenomenon so riled Albert Einstein that he called it “spooky action at a distance.”

Using these two principles, qubits can act as more sophisticated switches, enabling quantum computers to function in ways that allow them to solve difficult problems that are unmanageable using today’s computers.

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d). 1, 2 and 3

Correct Option: (d)

Explanation:

Short Range Devices (SRD) are radio devices that offer a low risk of interference with other radio services, usually because their transmitted power, and hence their range, is low. The definition 'Short Range Device' may be applied to many different types of wireless equipment, including various forms of:

  • Access control (including door and gate openers)
  • Alarms and movement detectors
  • Closed-circuit television (CCTV)
  • Cordless audio devices, including wireless microphones
  • Industrial control
  • Local Area Networks
  • Medical implants
  • Metering devices
  • Remote control
  • Radio frequency identification (RFID)

Which of the statements given above are correct ?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (d)

Explanation:

Biofilm is an association of micro-organisms in which microbial cells adhere to each other on living or non-living surfaces within a self-produced matrix of extracellular polymeric substance.

Biofilm formation is a multi-step process starting with attachment to a surface then formation of micro-colony that leads to the formation of three dimensional structure and finally ending with maturation followed by detachment.

During biofilm formation many species of bacteria are able to communicate with one another through a specific mechanism called quorum sensing. It is a system of stimulus to co-ordinate different gene expression.

Bacterial biofilm is less accessible to antibiotics and the human immune system and thus poses a big threat to public health because of its involvement in a variety of infectious diseases. Statement 3 is correct.

Biofilms may form on living or non-living surfaces and can be prevalent in natural, industrial and hospital settings.

Biofilms can be present on the teeth of most animals as dental plaque, where they may cause tooth decay and gum disease. Ststement 1 is correct

A combination of several pathogens can synergistically interact to form biofilms in the food industry. In food-processing environments, bacteria are able to exist as multispecies biofilms, from where both spoilage and pathogenic bacteria can contaminate food. For instance in the fishing industry, fresh fish products can suffer from biofilm formation by mixed pathogenic species (Aeromonas hydrophila, L. monocytogenes, S. enterica, or Vibrio spp.), which can imply significant health and economic issues. Synergistic interactions have been observed in a fresh-cut produce processing plant, where E. coli interacted with Burkholderia caryophylli and Ralstonia insidiosa to form mixed biofilms. Statement 2 is correct.

 

38. Consider the following statements in respect of probiotics :

Which of the statements given above is/are correct ?

(a) 1 only

(b) 2 only

(c) 1 and 3

(d) 2 and 3

Correct Option: (c)

Explanation:

Probiotics are foods that are made up of good live bacteria or yeasts that naturally stay in the human body. Human body is a host to good and bad bacteria. Whenever one gets an infection, there is more bacteria that is bad. 

Probiotic supplements add good bacteria to the human body.

These are a combination of beneficial bacteria and yeasts that naturally stay in the human body. Bacteria is not always a negative addition to the body, it is positive too. 

Probiotics are part of a larger picture concerning bacteria and your body which is called your microbiome. These microbes are a combination of:

  • Bacteria
  • Fungi (including yeasts)
  • Viruses
  • Protozoa

Statement 1 is correct.

 Benefits of Probiotics in a Nutshell:

  • Help the digestive system of the body
  • Keeping bad bacteria from getting out of control and making one ill
  • Create vitamins in the body
  • Help support the cells that line your gut to prevent bad bacteria that you may have consumed from entering your blood.
  • Breakdown and absorption of medications

Statement 2 is incorrect. And statement 3 is correct.

Explanation:

COVISHIELD vaccine is based on the platform which uses a recombinant, replication-deficient chimpanzee adenovirus vector encoding the SARS-CoV-2 Spike (S) glycoprotein. Following administration, the genetic material of part of coronavirus is expressed which stimulates an immune response. Hence the statement is incorrect.

Sputnik V is the world's first registered vaccine based on a well-studied human adenovirus vector platform. It has been approved for use in 71 countries with a total population of 4 billion people. The vaccine is named after the first Soviet space satellite. The launch of Sputnik-1 in 1957 reinvigorated space research around the world, creating a so-called “Sputnik moment” for the global community. The vaccine’s efficacy is 97.6%, based on the analysis of data on the incidence of coronavirus among Russians vaccinated with both vaccine components between December 5, 2020 and March 31, 2021. Statement 2 is correct.

Covaxin is an inactivated viral vaccine. This vaccine is developed with Whole-Virion Inactivated Vero Cell-derived technology. They contain inactivated viruses, which cannot infect a person but still can teach the immune system to prepare a defence mechanism against the active virus. Statement 3 is correct.

(a) Restoration of damaged coral reefs

(b) Development of building materials using plant residues

(c) Identification of areas for exploration/extraction of shale gas

(d) Providing salt licks for wild animals in forests/protected areas.

Correct Option: (a)

Explanation:

BIOROCK OR Mineral Accretion Technology is a coral reef restoration technology that utilizes low voltage electricity to improve the health and growth rates of corals and other marine organisms. 

The technology works by passing a small amount of electrical current through electrodes in the water.

When a positively charged anode and negatively charged cathode are placed on the seafloor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).

This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.

Fragments of broken corals are tied to the biorock structure, where they are able to grow at least four to six times faster than their actual growth as they need not spend their energy in building their own calcium carbonate skeletons.

Dignaga, (born c. 480 CE—died c. 540), Buddhist logician and author of the Pramaasamuccaya (“Compendium of the Means of True Knowledge”), a work that laid the foundations of Buddhist logic. Dignaga gave a new definition of “perception”: knowledge that is free from all conceptual constructions, including name and class concepts. In effect he regarded only pure sensation as perception. In his theory of inference he distinguished between inference for oneself and inference for the other and laid down three criteria of a valid middle term (hetu)—i.e., that it should “cover” the minor premise (paka), be present in the similar instances (sapaka), and be absent in dissimilar instances (vipaka). In his Hetucakra (“The Wheel of ‘Reason’”), Dignaga set up a matrix of nine types of middle terms, of which two yield valid conclusions, two contradictory, and the rest uncertain conclusions. Dignaga’s tradition was further developed in the 7th century by Dharmakarti.

NFTs typically contain references to digital files such as photos, videos, and audio. Because NFTs are uniquely identifiable, they differ from cryptocurrencies, which are fungible. The market value of an NFT is associated with the digital file it references.

Non-fungible tokens (NFTs) are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other. Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can serve as a medium for commercial transactions.

NFTs are unique cryptographic tokens that exist on a blockchain and cannot be replicated.

NFTs can represent real-world items like artwork and real estate.

“Tokenizing” these real-world tangible assets makes buying, selling, and trading them more efficient while reducing the probability of fraud.

NFTs can also function to represent individuals' identities, property rights, and more.

The distinct construction of each NFT has the potential for several use cases. For example, they are an ideal vehicle to digitally represent physical assets like real estate and artwork. Because they are based on blockchains, NFTs can also work to remove intermediaries and connect artists with audiences or for identity management. NFTs can remove intermediaries, simplify transactions, and create new markets.

Its purpose is to establish a comprehensive set of rules governing the oceans and to replace previous U.N. Conventions on the Law of the Sea, 1958 (UNCLOS I) which was adopted in 1958 and another in 1960 (UNCLOS II), since these two convention were believed to be inadequate.

The term Innocent Passage is defined under international law referring to a ship or aircraft’s right to enter and pass through another’s territory so long as it is not prejudicial to the peace, good order or security of the other state. Under Article 19 of the UNCLOS III it is defined “Passage is innocent so long as it is not prejudicial to the peace, good order or security of the coastal State.” Such passage shall take place in conformity with this Convention and with other rules of international law. The right of innocent passage of foreign ships through the territorial waters of a coastal state is one of the oldest and most universally recognized rules of public international law.

86. Which one of the following statements best reflects the issue which Senkaku Islands, sometimes mentioned in the news?

(a) It is generally believed that they are artificial islands made by a country around South China Sea.

(b) China and Japan engage in maritime disputes over these islands in East China Sea

(c) A permanent American military base has been set up there to help Taiwan to increase its defence capabilities.

(d) Through International Courts of Justice declared them as no man’s land, some South-East Asian countries claim them.

Correct Option: (b)

Explanation:

Senkaku/Diaoyu islands Dispute:

Japan and China claim the uninhabited islands, known as the Senkaku in Japan and Tiaoyu in China, as their own, but Japan has administered them since 1972. The Senkaku/Diaoyu Islands were formally claimed by Japan in 1895. After Japan’s defeat in World War II, the island chain was controlled by the US until 1971 before its return. Since then, Japan has administered the island chains. China began to reassert claims over the Senkaku/Diaoyu Islands in the 1970s, citing historic rights to the area. However, Japan does not recognise Chinese claims. More recently, there has been a flare up in the region. The Japanese government said on Thursday it had protested to China regarding a set of names recently assigned by Beijing to seabed zones in the East China Sea, including the Senkaku/Diaoyu islands. 

What is the dispute about?

The dispute is over the claim of Senkaku islands, which have been controlled by the Japanese since 1895.

However, between 1945 to 1972, the islands were administered by the United States. In 1971, the US handed over the authority to Japan in 1971.

The island chain, claimed by China, Taiwan and Japan, is made up of five islets and three barren rocks covering an area of 7 square kilometres.

89. With reference to Indian laws about wildlife protection, consider the following statements:

  1. Wild animals are the sole property of the government.
  2. When a wild animal is declared protected, such animal is entitled for equal protection whether it is found in protected areas or outside.
  3. Apprehension of a protected wild animal becoming a danger to human life is sufficient ground for its capture or killing.

Which of the statements given above is/are correct?

(a) 1 and 2

(b) 2 only

(c) 1 and 3

(d) 3 only

Correct Option: (a)

Explanation:

Statement 1 is correct: In a significant verdict, the Bombay High Court has ruled that wild animals including tiger should be treated as “government property for all purposes” and any damage caused by them should be compensated by the Government.

Statement 2 is correct: The law governing the subject of wildlife, the Wildlife (Protection) Act, 1972, does not discriminate between animals found in protected areas and outside. It provides for equal protection for wild animals irrespective of where they are found.

Statement 3 is incorrect: Only if the wild animal becomes a danger to human life or is diseased or disabled beyond recovery can it be allowed to be captured or killed by the competent authority, the Chief Wildlife Warden of the State. This provision is applicable to wild animals listed in Schedule I of the Wildlife (Protection) Act, 1972, which includes leopards. Mere apprehension or fear that a wild animal could endanger human life is not a ground for capture or killing.

The Chandellas of Bundelkhand

The Chandellas of Bundelkhand trace their descent to a mythical ancestor named Chandratreya, born of the moon. The Chandellas initially ruled as feudatories of the Gurjara−Pratiharas of Kannauj, and were involved in conflicts with the Pratiharas, the Palas, and the Kalachuris of Chedi (who bordered the Chandellas on the south). The Chandellas are well-known for their art and architecture, most notably for the fully developed Nagara- style temples at their original capital Khajuraho. The Lakshmana Temple (c. 930–950 CE), the Vishvanatha Temple (c. 999-1002 CE), and the Kandariya Mahadeva Temple (c. 1030 CE) were constructed during the reigns of Chandella rulers Yashovarman, Dhanga, and Vidyadhara respectively. They also commissioned a number of water bodies, palaces and forts at other places, including their strongholds of Jayapura-Durga (modern Ajaigarh), Kalanjara (modern Kalinjar), and their later capital Mahotsava-Nagara (modern Mahoba). In the first quarter of the 9th century CE, the dynasty was founded by Nannuka, who was the ruler of a small kingdom and established his capital at Kharjjuravahaka (Khajuraho).

Nannuka (c.831−845 CE) Was the founder king of Chandellas.

Vakpati (c. 845−865 CE) According to the Chandella inscriptions, Nannuka’s successor Vakpati defeated several enemies.

Jayashakti and Vijayashakti (c. 865−885 CE) Vakpati’s sons Jayashakti (Jeja) and Vijayashakti (Vija) consolidated the Chandella power. According to a Mahoba inscription, the Chandella territory was named “Jejakabhukti” after Jayashakti.

So, Pair 2 is incorrectly matched: Jayashakti also belonged to Chandela Dynasty

Pair 3 is correctly matched:

The Pratihara dynasty:

The Pratiharas were also known as the Gurjara−Pratiharas, as they originated from the Gurjaras who were primarily pastoralists and fighters. Importanat kings:

Nagabhatta II (c. 800–833 CE): Nagabhatta II was succeeded by his son Ramabhadra, who ruled briefly, and was succeeded by his son Mihira Bhoja.

Bhoja I / Mihir Bhoja (c.836−885 CE): Grandson of Nagabhatta II, who had a long reign of over 46 years and proved to be the most successful and popular ruler of Pratiharas.

So Pair 4 is incorrectly matched: Bhoja was king from the Pratihara Dynasty.

93. Which one of the following statements about Sangam literature in ancient South India is correct ?

(a) Sangam poems are devoid of any reference to material culture.

(b) The social classification of Varna was known to Sangam poets.

(c) Sangam poems have no references to warrior ethic.

(d) Sangam literature refers to magical forces as irrational.

Correct Option: (b)

Explanation:

Sangam Literature has references to material culture and war tactics and ethics. The varna system was not practiced but it was known. 

94. “Yogavasistha” was translated into Persian by Nizamuddin Panipati during the reign of:

(a) Akbar

(b) Humayun

(c) Shahjahan

(d) Aurangzeb

Correct Option: (a)

Explanation:

YogaVasistha was translated into Persian multiple times throughout the Mughal Dynasty, as commanded by Akbar, Jahangir, and Darah Shikuh. Nizam al-Din Panipati completed one of these translations, known as the Jug-Basisht, in the late sixteenth century AD.

95. The world’s second tallest statue in sitting pose of Ramanuja was inaugurated by the Prime Minister of India at Hyderabad recently. Which one of the following statements correctly represents the, teachings of Ramanuja?

(a) The best means of salvation was devotion.

(b) Vedas are eternal, self-existent and wholly authoritative.

(c) Logical arguments were essential means for the highest bliss.

(d) Salvation was to be obtained through meditation.

Correct Option: (a)

Explanation:

Ramanuja

He was born in Tamil Nadu in the eleventh century. He was deeply influenced by the Alvars. He firmly believed that intense devotion to Vishnu was the best means to attain salvation. He propounded the doctrine of Vishishtadvaita.

Vishishtadvaita is formed by the two words: vishisht meaning qualified and advaita meaning oneness of the individual soul and the Supreme God. In other words it means qualified oneness wherein the soul, even when united with the Supreme God, remained distinct.

The new strand of bhakti that developed in north India subsequently was greatly inspired by Ramanujam's doctrine.

96. The Prime Minister recently inaugurated the new Circuit House near Somnath Temple at Veraval. Which of the following statements are correct regarding Somnath Temple ?

  1. Somnath Temple is one of the Jyotirlinga shrines.
  2. A description of Somnath Temple was given by Al-Biruni.
  3. Pran Pratishtha of Somnath Temple (installation of the present day temple) was done by President S. Radhakrishnan.

Select the correct answer using the code given below :

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (a)

Explanation:

Somnath Temple at Somnath, Gujrat is one of the most sacred pilgrimage sites for Hindus and is believed to be first among the twelve Jyotirlinga shrines of Shiva. 

Ancient Indian traditions maintain a close relationship of Somnath with release of Chandra (Moon God) from the curse of his father-in-law Daksha Prajapati. Moon was married to Twenty-Seven daughters of Daksha. However, he favoured Rohini and neglected other queens. The aggrieved Daksha cursed Moon and the Moon lost power of light. With the advice of Prajapita Brahma, Moon arrived at the Prabhas Teerth and worshipped Bhagvan Shiva. Pleased with the great penance and devotion of Moon, Bhagvan Shiva blessed him and relieved him from the curse of darkness. Pauranic traditions maintain that Moon had built a golden temple, followed by a silver temple by Ravana, Bhagvan Shree Krishna is believed to have built Somnath temple with Sandalwood.

The later sources of history account for several desecrations by Muslims invaders during eleventh to eighteen century A.D. The temple was rebuilt every time with the reconstructive spirit of the people. The modern temple was reconstructed with the resolve of Sardar Patel who visited the ruins of Somnath temple on November 13 1947. Then President of India, Dr. Rajendra Prasad, did the Pran-Pratistha at the existing temple on 11 May 1951.

So statement 3 is incorrect.

97. Which one of the following statements best describes the role of B cells and T cells in the human body ?

(a) They protect the body from environmental allergens.

(b) They alleviate the body’s pain and inflammation.

(c) They act as immunosuppressants in the body.

(d) They protect the body from the diseases caused by pathogens.

Correct Option: (d)

Explanation:

pTreg cells generation is influenced by a specific type of TCR signaling, and costimulation, and through cooperation with other signals, such as TGF-β, IL-2, and ATRA. These conditions suggest that pTreg cell differentiation could be restricted to precise locations such us mucosal surfaces where they may regulate immune responses to harmless antigens such as commensal microbiota and prevent allergic inflammation. Supporting these ideas, “studies using Rag-1-deficient T-B monoclonal mice sufficient or deficient in FOXP3 demonstrated that TCR transgenic pTreg cells were sufficient to establish mucosal tolerance and control allergic inflammation induced by the model antigen recognized by the TCR” 

98. Consider the following statements:

  1. Other than those made by humans, nanoparticles do not exist in nature.
  2. Nanoparticles of some metallic oxides are used in the manufacture of some cosmetics.
  3. Nanoparticles of some commercial products which enter the environment are unsafe for humans.

Which of the statements given above is/are correct?

(a) .1 only

(b). 3 only

(c). 1 and 2

(d). 2 and 3

Correct Option: (d)

Explanation:

Statement 1 is incorrect: Natural nanoparticles are formed from magma spewing volcanoes;others are formed by forces such as of oceanic breakers, tides, river currents, etc.

Statement 2 and 3 are correct: Among the metal oxide NPs present in cosmetic products, amorphous silica (SiO2), zinc oxide (ZnO) and particularly titanium dioxide (TiO2) are the most frequent. The thing that makes nanoparticles so interesting for applications is that materials in nanosize have properties (optical, chemical, magnetic, biological, electrical, and mechanical) that are completely different from the properties of the same material in bulk. These new properties may cause a problem if nanoparticles are unintentionally released – very few of these particles exist in nature and we as humans have not been exposed to them throughout evolution. Therefore, we cannot be sure that our body have developed defense mechanisms to deal with them.  

An important consideration in the deposition of particles in the respiratory system is the lung-lining fluid (a complex mixture of lipids and surfactant proteins) since any depositing material quickly becomes coated in these surfactant proteins and lipids. Such a coating gives the deposited particle its ‘biological identity’ This so-called protein corona, which is likely to play a role in the way particles interact with lung cells such as alveolar macrophages. 

Several studies on workers exposed to carbon nanotubes have shown a significant increase of biomarkers of fibrosis. The organization for cancer research (IARC) of the World Health Organization (WHO) have classified one type of carbon nanotubes (Mitzui 7) as potentially carcinogenic in humans [IARC 111]. 

99. Consider the following statements:

DNA Barcoding can be a tool to :

  1. assess the age of a plant or animal.
  2. distinguish among species that look alike.
  3. identify undesirable animal or plant materials in processed foods.

Which of the statements given above is/are correct?

(a) 1 only

(b) 3 only

(c) 1 and 2

(d) 2 and 3

Correct Option: (d)

Explanation:

Statement 1 is incorrect: To measure the age of plant and animal remains from the more recent past, scientists use a radioactive isotope of carbon, called carbon-14, as their clock. As carbon-14 decays, with a half-life of about 5,730 years, it becomes nitrogen-14. Using this clock, they have dated bones, campfires and other objects as old as 60,000 years, and in some cases even older.

Statement 2 and 3 is correct: DNA barcoding uses specific regions of DNA in order to identify species. Initiatives are taking place around the world to generate DNA barcodes for all groups of living organisms and to make these data publically available in order to help understand, conserve, and utilize the world's biodiversity. For land plants the core DNA barcode markers are two sections of coding regions within the chloroplast, part of the genes, rbcL and matK. In order to create high quality databases, each plant that is DNA barcoded needs to have a herbarium voucher that accompanies the rbcL and matK DNA sequences. The quality of the DNA sequences, the primers used, and trace files should also be accessible to users of the data. Multiple individuals should be DNA barcoded for each species in order to check for errors and allow for intraspecific variation. The world's herbaria provide a rich resource of already preserved and identified material and these can be used for DNA barcoding as well as by collecting fresh samples from the wild. These protocols describe the whole DNA barcoding process, from the collection of plant material from the wild or from the herbarium, how to extract and amplify the DNA, and how to check the quality of the data after sequencing.

100. Consider the following

  1. Carbon monoxide
  2. Nitrogen oxide
  3. Ozone
  4. Sulphur dioxide

Excess of which of the above in the environment is/are cause(s) of acid rain?

(a) 1, 2 and 3

(b) 2 and 4 only

(c) 4 only

(d) 1, 3 and 4

Correct Option: (b)

Explanation:

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.  These then mix with water and other materials before falling to the ground.

While a small portion of the SO2 and NOX that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.  The major sources of SO2 and NOX in the atmosphere are:

Burning of fossil fuels to generate electricity.  Two thirds of SO2 and one fourth of NOX in the atmosphere come from electric power generators.

Vehicles and heavy equipment.

Manufacturing, oil refineries and other industries.

Winds can blow SO2 and NOX over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources. 

So by eliminating, we get (b) as the correct answer.

Types of questions

STATIC (Compulsory):

1.  With reference to the Indian economy, consider the following statements:

  1. An increase in Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee.
  2. An increase in the Real Effective Exchange Rate (REER) indicates an improvement in trade competitiveness.
  3. An increasing trend in domestic inflation relative to inflation in other countries is likely to cause an increasing divergence between NEER and REER.

Which of the above statements are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (c)

Explanation:

Statement 1 is correct: NEER is a measure of value of a currency against a weighted average of several foreign currency. An increase in NEER indicates appreciation of rupee.

Statement 2 is incorrect: An increase in REER implies that exports become more expensive and imports become cheaper; therefore, an increase indicates a loss in trade competitiveness.

Statement 3 is correct: NEER is the weighted geometric average of the bilateral nominal exchange rates of the home currency in terms of foreign currencies. The REER is the weighted average of NEER adjusted by the ratio of domestic price to foreign prices. Increasing trend in domestic inflation relative to inflation in other countries creates a divergence in NEER and REER.

2. With reference to the Indian economy, consider the following statements:

  1. If the inflation is too high, Reserve Bank of India (RBI) is likely to buy government securities.
  2. If the rupee is rapidly depreciating, RBI is likely to sell dollars in the market.
  3. If interest rates in the USA or European Union were to fall, that is likely to induce RBI to buy dollars.

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (b)

Explanation:

Statement 1 is incorrect: If the inflation is high RBI tries to reduce the liquidity from the market, by selling Government securities to the public via open market operation.

Statement 2 is correct: Rupee depreciation means, fall in value of rupee with respect to dollar. In free floating exchange rate regime, depreciation takes place when the demand for dollar is more than the supply.thus, RBI is likely to sell dollars in the economy to increase the supply of the dollar.

Statement 3 is correct: If the interest rate in US and EU falls, there will be an inflow of dollars in the Indian market, leading to appreciation of the rupee. To reduce the supply of dollar in the economy, RBI will like to buy the dollars from the market.

3. Consider the following statements:

  1. A bill amending the Constitution requires a prior recommendation of the President of India.
  2. When a Constitution Amendment Bill is presented to the President of India, it is obligatory for the President of India to give his/her assent.

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (b)

Explanation:

Statement 1 is incorrect: No prior approval of the President is required for the Constitutional Amendment Act.

Statement 2 is correct: It is obligatory for the President to give his assent, when a Constitutional Amendment Bill is presented before him. The President cannot exercise any veto power regarding the Constitutional Amendment Bill.

Statement 3 is correct: Constitutional Amendment Bill needs to be passed by both the houses separately by a special majority, and no joint sitting is allowed regarding Constitutional Amendment Bill.

4. Which of the following is/are the exclusive power(s) of Lok Sabha?

  1. To ratify the declaration of Emergency
  2. To pass a motion of no-confidence against the Council of Ministers
  3. To impeach the President of India

Select the correct answer using the code given below:

(a) 1 and 2

(b) 2 only

(c) 1 and 3

(d) 3 only

Correct Option: (b)

Explanation:

Statement 2 is correct: Article 75 of the Constitution says that the council of ministers shall be collectively responsible to the Lok Sabha. It means that the ministry stays in office so long as it enjoys confidence of the majority of the members of the Lok Sabha. In other words, the Lok Sabha can remove the ministry from office by passing a noconfidence motion. The motion needs the support of 50 members to be admitted. (Source: LakshmiKant)

Statement 1 is incorrect: If the President is satisfied that a grave emergency exists whereby the security of India or of any part of the territory thereof is threatened, whether by war or external aggression or armed rebellion, he may, by Proclamation, made a declaration to that effect in respect of the whole of India or of such part of the territory. Every Proclamation issued under this article shall be laid before each House of Parliament. (Source: https://indiankanoon.org/doc/1018568/)

Statement 3 is incorrect: If Parliament. These charges should be signed by one-fourth members of the House (that framed the charges), and a 14 days’ notice should be given to the President. After the impeachment resolution is passed by a majority of two-thirds of the total membership of that House, it is sent to the other House, which should investigate the charges. The President has the right to appear and to be represented at such investigation. If the other House also sustains the charges and passes the impeachment resolution by a majority of two-thirds of the total membership, then the President stands removed from his office from the date on which the resolution is so passed. (Source: LakshmiKant)

5. With reference to anti-defection law in India, consider the following statements:

  1. The law specifies that a nominated legislator cannot join any political party within six months of being appointed to the House.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Correct Option: (b)

Explanation:

Statement 1 is incorrect: A nominated member of a House becomes disqualified for being a member of the House if he joins any political party after the expiry of six months from the date on which he takes his seat in the House. This means that he may join any political party within six months of taking his seat in the House without inviting this disqualification.  (Source: LakshmiKant)

Statement 2 is correct: The law does not specify a time-period for the Presiding Officer to decide on a disqualification plea. 

6. In India, which one of the following is responsible for maintaining price stability by controlling inflation ?

(a) Department of Consumer Affairs

(b) Expenditure Management Commission

(c) Financial Stability and Development Council

(d) Reserve Bank of India

Correct Option: (d)

Explanation:

Option (d) is correct:  Reserve bank OF India is responsible for maintaining price stability and controlling inflation.

It is the responsibility of MPC in India, but RBI itself plays a large role in MPC and also carries out task of monetary policy committee.

So RBI is the correct answer if MPC is not given in the options.

(b) This would create a local self-governing body in that area.

(c) This would convert that area into a Union Territory.

(d) The State having such areas would be declared a Special Category State.

Correct Option: (a)

Explanation:

Statement (a) is correct: Governor can make regulations for the peace and good government of a scheduled area after consulting the tribes advisory council. Such regulations may prohibit or restrict the transfer of land by tribal to non tribal members or among members of the scheduled tribes, regulate the allotment of land to members of the scheduled tribes.

Statement b is incorrect: Tribal advisory council is an advisory body , not a governing body.

Statement c and d are incorrect (Self explanatory)

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Correct Option: (b)

Explanation:

COVISHIELD vaccine is based on the platform which uses a recombinant, replication-deficient chimpanzee adenovirus vector encoding the SARS-CoV-2 Spike (S) glycoprotein. Following administration, the genetic material of part of coronavirus is expressed which stimulates an immune response. Hence the statement is incorrect.

Sputnik V is the world's first registered vaccine based on a well-studied human adenovirus vector platform. It has been approved for use in 71 countries with a total population of 4 billion people. The vaccine is named after the first Soviet space satellite. The launch of Sputnik-1 in 1957 reinvigorated space research around the world, creating a so-called “Sputnik moment” for the global community. The vaccine’s efficacy is 97.6%, based on the analysis of data on the incidence of coronavirus among Russians vaccinated with both vaccine components between December 5, 2020 and March 31, 2021. Statement 2 is correct.

Covaxin is an inactivated viral vaccine. This vaccine is developed with Whole-Virion Inactivated Vero Cell-derived technology.

5. “Biorock technology” is talked about in which one of the following situations ?

(a) Restoration of damaged coral reefs

(b) Development of building materials using plant residues

(c) Identification of areas for exploration/extraction of shale gas

(d) Providing salt licks for wild animals in forests/protected areas.

Correct Option: (a)

Explanation:

BIOROCK OR Mineral Accretion Technology is a coral reef restoration technology that utilizes low voltage electricity to improve the health and growth rates of corals and other marine organisms. 

The technology works by passing a small amount of electrical current through electrodes in the water.

When a positively charged anode and negatively charged cathode are placed on the seafloor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).

This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.

Fragments of broken corals are tied to the biorock structure, where they are able to grow at least four to six times faster than their actual growth as they need not spend their energy in building their own calcium carbonate skeletons.

Senkaku/Diaoyu islands Dispute:

Japan and China claim the uninhabited islands, known as the Senkaku in Japan and Tiaoyu in China, as their own, but Japan has administered them since 1972. The Senkaku/Diaoyu Islands were formally claimed by Japan in 1895. After Japan’s defeat in World War II, the island chain was controlled by the US until 1971 before its return. Since then, Japan has administered the island chains. China began to reassert claims over the Senkaku/Diaoyu Islands in the 1970s, citing historic rights to the area. However, Japan does not recognise Chinese claims. More recently, there has been a flare up in the region. The Japanese government said on Thursday it had protested to China regarding a set of names recently assigned by Beijing to seabed zones in the East China Sea, including the Senkaku/Diaoyu islands.

Explanation:

Somnath Temple at Somnath, Gujrat is one of the most sacred pilgrimage sites for Hindus and is believed to be first among the twelve Jyotirlinga shrines of Shiva. 

Ancient Indian traditions maintain a close relationship of Somnath with release of Chandra (Moon God) from the curse of his father-in-law Daksha Prajapati. Moon was married to Twenty-Seven daughters of Daksha. However, he favoured Rohini and neglected other queens. The aggrieved Daksha cursed Moon and the Moon lost power of light. With the advice of Prajapita Brahma, Moon arrived at the Prabhas Teerth and worshipped Bhagvan Shiva. Pleased with the great penance and devotion of Moon, Bhagvan Shiva blessed him and relieved him from the curse of darkness. Pauranic traditions maintain that Moon had built a golden temple, followed by a silver temple by Ravana, Bhagvan Shree Krishna is believed to have built Somnath temple with Sandalwood.

The later sources of history account for several desecrations by Muslims invaders during eleventh to eighteen century A.D. The temple was rebuilt every time with the reconstructive spirit of the people. The modern temple was reconstructed with the resolve of Sardar Patel who visited the ruins of Somnath temple on November 13 1947. Then President of India, Dr. Rajendra Prasad, did the Pran-Pratistha at the existing temple on 11 May 1951.

So statement 3 is incorrect.
