  1. “Souls are not only the property of animal and plant life, but also of…

    "Souls are not only the property of animal and plant life, but also of rocks, running water and many other natural objects not looked on as living by other religious sects." The above statement reflects one of the core beliefs of which one of the following religious sects of ancient India?

    1. ABuddhism
    2. BJainism
    3. CShaivism
    4. DVaishnavism
    Answer and explanation

    Correct answer: B

    The statement reflects the fundamental Jain doctrine that the entire cosmos is alive. According to Jain philosophy, souls (Jivas) are not restricted to humans, animals, and plants but are also present in elements like rocks (earth), running water, air, and fire. These are categorized as Sthavara Jivas (immobile living beings) or Ekendriya (one-sensed beings). This ontological belief is the foundation for the rigorous practice of Ahimsa (non-violence) in Jainism, as harming any natural element is considered harming a living soul. Note that Anekantavada refers to the doctrine of non-absolutism or the many-sidedness of truth, which is an epistemological concept distinct from the belief in the omnipresence of souls.

    Consider the following markets: 1. Government Bond Market 2. Call Money Market 3. Treasury Bill Market 4. Stock Market How many of the above are included in capital markets?

    1. AOnly one
    2. BOnly two
    3. COnly three
    4. DAll four
    Answer and explanation

    Correct answer: B

    Capital markets are financial markets where long-term securities, such as stocks and bonds, are traded. They provide a platform for raising capital for businesses and governments.

    On the other hand, Money markets are financial markets where short-term securities such as T-Bill, C-Paper, Cash Management Bills, Ways and Means advances, etc are traded.

    * Statement 1 is correct- Government bonds are long-term debt securities issued by governments to finance their activities. The government bond market is a part of the capital market as it involves the trading of long-term debt securities.

    * Statement 2 is incorrect- The call money market is a short-term market where funds are borrowed and lent for very short durations, usually overnight. It deals with short-term funds, and its transactions are not classified as part of the capital market.

    * Statement 3 is incorrect- Treasury bills are short-term debt instruments issued by governments to finance their short-term cash flow requirements. The treasury bill market, similar to the call money market, deals with short-term instruments and is not considered part of the capital market.

    * Statement 4 is correct- The stock market, also known as the equity market or share market, is where shares or stocks of publicly listed companies are bought and sold. The stock market is a part of the capital market as it involves the trading of ownership interests (equity securities) in companies.

  3. Consider the following statements: Statement-I: The Supreme Court of India has held in some…

    Consider the following statements: Statement-I: The Supreme Court of India has held in some judgements that the reservation policies made under Article 16(4) of the Constitution of India would be limited by Article 335 for maintenance of efficiency of the administration. Statement-II: Article 335 of the Constitution of India defines the term 'efficiency of administration'. Which one of the following is correct in respect of the above statements?

    1. ABoth Statements-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
    2. BBoth Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
    3. CStatement-I is correct but Statement-II is incorrect
    4. DStatement-I is incorrect but Statement-II is correct
    Answer and explanation

    Correct answer: C

    * Statement I is correct: It has frequently been argued that reservation is contrary to efficiency and merit. Even the Supreme Court of India appeared to have agreed with this argument in some of its judgments, holding that Article 335 mention of the term efficiency of administration will limit the scope of Article 16(4) provision for reservation in services.

    * Statement II is incorrect: Article 335 of the Constitution of India states that the claims of the members of the Scheduled Castes and the Scheduled Tribes shall be taken into consideration, consistently with the maintenance of efficiency of administration, in the making of appointments to services and posts in connection with the affairs of the Union or of a State.

    * Article 335 of the Indian Constitution only mentions the efficiency of administration and does not define the same.

  4. Aerial metagenomics’ best refers to which one of the following situations?

    Aerial metagenomics' best refers to which one of the following situations?

    1. ACollecting DNA samples from air in a habitat at one go
    2. BUnderstanding the genetic makeup of avian species of a habitat
    3. CUsing air-borne devices to collect blood samples from moving animals
    4. DSending drones to inaccessible areas to collect plant and animal samples from land surfaces and water bodies
    Answer and explanation

    Correct answer: A

    Aerial metagenomics refers to the scientific technique of collecting and analyzing DNA samples directly from the air to identify the biological community present in a habitat.

    * Metagenomics: This is the study of genetic material (genomes) recovered directly from environmental samples (like soil, water, or air). It bypasses the need for isolating and culturing individual species in a lab. * Environmental DNA (e-DNA): Organisms shed DNA into their surroundings through various means such as breath, skin, fur, or waste. This genetic material found in the environment is known as e-DNA. * Aerial Sampling: In 'Aerial' metagenomics, researchers use specialized filters or vacuum systems to capture this e-DNA from the air. This allows for the simultaneous monitoring of multiple species (animals, plants, fungi, and microbes) in a specific area at one go, providing a non-invasive way to track biodiversity.

    Hence, option A is correct.

    * Statement 2 is correct: The role of Home Guards is to serve as an auxiliary force to the Police in the maintenance of internal security situations, help the community in any kind of emergency such as an air raid, fire, cyclone, earthquake, epidemic, etc., help in the maintenance of essential services, promote communal harmony and assist the administration in protecting weaker sections, participate in socio-economic and welfare activities and perform Civil Defence duties.

    * Statement 3 is correct: Fifteen Border Wing Home Guards (BWHG) Battalions have been raised in the border States viz. Punjab (6 Bns.), Rajasthan ( 4 Bns.), Gujarat (2 Bns.), and one each Battalion for Meghalaya, Tripura, and West Bengal to serve as an auxiliary to Border Security Force for preventing infiltration on the international border/coastal areas, guarding of VA/VPs and lines of communication in the vulnerable area at the time of external aggression.

    2. BOnly three
    3. COnly four
    4. DAll five
    Answer and explanation

    Correct answer: B

    The Fifteenth Finance Commission (XVFC) recommended the following criteria and weights for horizontal tax devolution among states for the 2021-26 period:

    1. Income Distance (45%): The distance of a state's income from the state with the highest income. 2. Population (15%): Based on the 2011 Census data. 3. Area (15%): To account for the higher cost of providing services in larger geographical areas. 4. Forest and Ecology (10%): Calculated based on the share of the dense forest of each state in the total dense forest of all states. 5. Demographic Performance (12.5%): This criterion was introduced to reward states that have made progress in lowering their fertility rates (using 1971 population data as a benchmark). 6. Tax and Fiscal Efforts (2.5%): To reward states with higher tax collection efficiency.

    Analysis of the given list: - Demographic performance: Included (Criterion 5) - Forest and ecology: Included (Criterion 4) - Tax and fiscal efforts: Included (Criterion 6) - Governance reforms: Not included as a criterion for horizontal devolution. - Stable government: Not included as a criterion for horizontal devolution.

    Apart from population, area, and income distance, the Commission used three criteria from the list provided (Demographic performance, Forest and ecology, and Tax and fiscal efforts).

They build nests, known as dreys, in tree branches, hollows, or crevices using twigs and leaves, rather than making burrows in the ground.

    Statement 2 is Correct: Many squirrel species exhibit "scatter hoarding" behavior. They store food materials like nuts and seeds by burying them in various shallow locations in the ground to retrieve them during times of food scarcity. This behavior is a key ecological process for seed dispersal.

    Statement 3 is Correct: Squirrels are opportunistic omnivores. While their diet primarily consists of seeds, nuts, fruits, and fungi, they also consume insects, caterpillars, bird eggs, and occasionally small vertebrates like lizards or young birds.

    Consider the following statements: Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. Statement-II: Uranium, enriched to the extent of at least 60% is required for the production of electricity. Which one of the following is correct in respect of the above statements?

    1. ABoth Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
    2. BBoth Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
    3. CStatement-I is correct but Statement-II is incorrect
    4. DStatement-I is incorrect but Statement-II is correct
    Answer and explanation

    Correct answer: C

    The Assertion is Correct: India possesses domestic uranium deposits in regions such as the Singhbhum Shear Zone (Jharkhand) and the Cuddapah Basin (Andhra Pradesh). Despite these reserves, coal remains the primary source of electricity in India, accounting for over 70% of the total power generation.

    The Reason is Incorrect: Commercial electricity production does not require 60% enrichment. India's Pressurised Heavy Water Reactors (PHWRs) use natural uranium (0.7% U-235) as fuel, while Light Water Reactors (LWRs) typically use Low Enriched Uranium (LEU) enriched to 3-5%. Uranium enriched to 60% or more is classified as Highly Enriched Uranium (HEU), which is used for research reactors or naval propulsion, not standard power plants.

    The Reason is factually incorrect and does not explain the Assertion.

    Consider the following statements: Statement-I: In the post-pandemic recent past, many Central Banks worldwide had carried out interest rate hikes. Statement-II: Central Banks generally assume that they have the ability to counteract the rising consumer prices via monetary policy means. Which one of the following is correct in respect of the above statements?

    1. ABoth Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
    2. BBoth Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
    3. CStatement-I is correct but Statement-II is incorrect
    4. DStatement-I is incorrect but Statement-II is correct
    Answer and explanation

    Correct answer: A

    * Statement-I is correct: In the aftermath of the COVID-19 pandemic, global economies faced significant inflationary pressures due to supply chain disruptions and increased demand. To curb this inflation, many central banks, including the US Federal Reserve and the Reserve Bank of India, initiated a series of interest rate hikes to reduce liquidity in the market. * Statement-II is correct: A core principle of modern central banking is the belief that monetary policy tools—specifically adjusting interest rates—can influence economic activity and price levels. By raising rates, central banks aim to reduce spending and investment, thereby cooling down rising consumer prices. * Relationship: Statement-II explains the underlying logic behind the actions mentioned in Statement-I. Central banks carried out interest rate hikes *because* they operate under the assumption that such monetary policy measures are effective tools to counteract inflation. Thus, Statement-II is the correct explanation for Statement-I.

    Ilmenite and rutile, abundantly available in certain coastal tracts of India, are rich sources of which one of the following?

    1. AAluminium
    2. BCopper
    3. CIron
    4. DTitanium
    Answer and explanation

    Correct answer: D

    * Ilmenite (FeTiO3) and Rutile (TiO2) are both minerals that contain high concentrations of titanium.

    * Titanium is a strong and lightweight metal known for its excellent corrosion resistance and high strength-to-weight ratio. It is widely used in various industries, including aerospace, automotive, medical, and construction.

    * In India, certain coastal tracts are known for their significant ilmenite and rutile deposits. Hence these minerals are also called beach sand minerals. These minerals are commonly found in beach sand deposits and are extracted through beach sand mining operations. The extracted ilmenite and rutile are processed to obtain titanium dioxide (TiO2), which is then further refined to produce metallic titanium.

    * Beach sand is rich in seven heavy minerals—ilmenite, leucoxene, rutile, zircon, sillimanite, garnet and monazite.

Mains Q&A 80

  1. You have just been appointed as Additional Director General of Central Public Works Department. The Chief Architect of your division, who is to retire in six months, is passionately working on a very important project, the successful completion of which would earn him a lasting reputation for the rest of his life. A new lady architect, Seema, trained at Manchester School of Architecture, UK joined as Senior Architect in your division. During the briefing about the project, Seema made some suggestions which would not only add value to the project, but would also reduce completion time. This has made the Chief Architect insecure and he is constantly worried that all the credit will go to her. Subsequently, he adopted a passive and aggressive behaviour towards her and has become disrespectful to her. Seema felt it embarrassing as the Chief Architect left no chance of humiliating her. He would very often correct her in front of other colleagues and raise his voice while speaking to her. This continuous harassment has resulted in her losing confidence and selfesteem. She felt perpetually tensed, anxious and stressed. She appeared to be in awe of him since he has had a long tenure in the office and has vast experience in the area of her work. You are aware of her outstanding academic credentials and career record in her previous organisations. However, you fear that this harassment may result in compromising her much needed contribution in this important project and may adversely impact her emotional well-being. You have also come to know from her peers that she is contemplating tendering her resignation. (a) What are the ethical issues involved in the above case? (b) What are the options available to you in order to complete the project as well as to retain Seema in the organization? (c) What would be your response to Seema’s predicament? What measures would you institute to prevent such occurrences from happening in your organization?
