Question 2 of 15
2. Question
1 pointsConsider the following pairs of agricultural inputs and their associated functions:
Term Description - Azotobacter
Free-living nitrogen-fixing bacteria used for non-leguminous crops such as wheat and maize - Mycorrhiza
Symbiotic fungi that enhance phosphorus uptake and improve drought resistance in plants - Green Manure
Practice of growing and incorporating crops like sunnhemp or dhaincha into the soil to improve fertility How many of the above pairs are correctly matched?
Correct
Answer: (c)
Explanation:
The use of bio-fertilizers and organic soil amendments is a key component of sustainable agriculture and the National Mission for Sustainable Agriculture (NMSA) in India.
- Pair 1 is correctly matched: Azotobacter is a genus of free-living (non-symbiotic) nitrogen-fixing bacteria. Unlike Rhizobium, which requires a host legume to form nodules, Azotobacter can fix atmospheric nitrogen while living independently in the soil. It is extensively used as a bio-fertilizer for non-leguminous crops like wheat, maize, mustard, and vegetables. It also produces growth-promoting substances like vitamins and gibberellins.
- Pair 2 is correctly matched: Mycorrhiza refers to the symbiotic association between fungi and the roots of higher plants. The fungi colonize the root system, providing increased water and phosphorus absorption capabilities (acting like an extension of the root system), while the plant provides the fungi with carbohydrates. This relationship significantly improves the plant’s drought resistance and tolerance to soil salinity.
- Pair 3 is correctly matched: Green Manure involves the cultivation of quick-growing leafy crops which are then ploughed back and incorporated into the soil while still green. This improves soil structure, increases organic matter, and adds nitrogen. Common examples in India include Sunnhemp (Crotalaria juncea) and Dhaincha (Sesbania aculeata).

1 pointsWith reference to the Agriculture Infrastructure Fund (AIF), consider the following statements:
- It provides support in the form of interest subvention and credit guarantee coverage for financing post-harvest management infrastructure and community farming assets.
- The scheme is implemented exclusively through the National Bank for Agriculture and Rural Development (NABARD).
- The scheme extends support to both public and private entities, including Farmer Producer Organizations (FPOs), cooperatives, and agri-entrepreneurs.
Which of the statements given above are correct?
Correct
Answer: (c)
Explanation:
Statement 1 is correct: The AIF is specifically designed to provide a medium-to-long term debt financing facility. It offers:
- Interest Subvention: 3% per annum on loans up to ₹2 crore for a maximum period of 7 years.
- Credit Guarantee: Coverage for loans up to ₹2 crore under the CGTMSE (Credit Guarantee Fund Trust for Micro and Small Enterprises) scheme.
Statement 2 is incorrect: While NABARD is a key partner and provides refinancing, the scheme is not implemented exclusively through it. It is implemented by all Scheduled Commercial Banks, Scheduled Cooperative Banks, Regional Rural Banks (RRBs), Small Finance Banks, and Non-Banking Financial Companies (NBFCs). The Ministry of Agriculture and Farmers Welfare provides the overall management.
Statement 3 is correct: The scheme has a very broad eligibility base. It targets:
- Primary entities: Farmers, FPOs, PACS (Primary Agricultural Credit Societies), and Marketing Cooperative Societies.
- Entrepreneurs: Agri-entrepreneurs, startups, and private sector entities.
- Public entities: Central/State agencies or local bodies-sponsored Public-Private Partnership (PPP) projects.

Question 4 of 15
4. Question
1 pointsWith reference to the World Drought Atlas, consider the following statements:
- It has been launched jointly by the United Nations Convention to Combat Desertification (UNCCD) and the European Commission’s Joint Research Centre.
- The Atlas examines drought impacts on sectors such as agriculture, ecosystems, and inland navigation.
- It focuses exclusively on natural causes of drought, excluding human-induced factors.
Which of the statements given above are correct?
Correct
Answer: (a)
Explanation:
- Statement 1 is correct: The Atlas is a collaborative effort between the United Nations Convention to Combat Desertification (UNCCD) and the European Commission’s Joint Research Centre (JRC). It was developed to provide a comprehensive, data-driven overview of drought risks across the globe.
- Statement 2 is correct: The Atlas goes beyond mere rainfall data. It examines the multi-sectoral impacts of drought, specifically focusing on how it affects agriculture (crop failure), ecosystems (loss of biodiversity), and inland navigation (lowering of river levels affecting transport), among others.
- Statement 3 is incorrect: The World Drought Atlas does not exclude human-induced factors. In fact, one of its primary purposes is to highlight how climate change (human-induced) and land-use changes are exacerbating natural drought cycles. It integrates both meteorological data and anthropogenic influences to provide a realistic risk profile.

Question 5 of 15
5. Question
1 pointsConsider the following statements regarding the trends in the Indian agricultural sector:
- The share of allied sectors like livestock and fisheries in the total Gross Value Added (GVA) from agriculture has been increasing steadily.
- India’s agri-food exports have shown a consistent decline in the last five years due to increased domestic consumption.
- The proportion of small and marginal farmers accessing institutional credit has increased significantly in recent years.
Which of the statements given above are correct?
Correct
Answer: (c)
Explanation:
- Statement 1 is correct: There is a visible structural shift in Indian agriculture. While the share of traditional crops in the Agricultural GVA has remained relatively stagnant or declined, the allied sectors—particularly livestock and fisheries—have been growing at a much faster rate (often 6-8% annually). Livestock now accounts for nearly 30% of the total GVA from the Agriculture and Allied sector.
- Statement 2 is incorrect: While domestic consumption is indeed rising, India’s agri-food exports have not shown a consistent decline. In fact, India reached record-high agricultural exports (exceeding $50 billion) in recent years (FY22 and FY23), driven by commodities like marine products, non-basmati rice, sugar, and spices. While there are occasional fluctuations due to export bans (e.g., on wheat or broken rice), the five-year trend has generally been positive.
- Statement 3 is correct: Thanks to targeted policies like the Kisan Credit Card (KCC) saturation drives, the interest subvention scheme, and the Priority Sector Lending (PSL) mandates (which include a specific sub-target for Small and Marginal Farmers), the percentage of these farmers accessing formal bank credit has seen a significant upward trend, reducing their dependence on informal moneylenders.

Question 6 of 15
6. Question
1 pointsConsider the following statements regarding settlement patterns in India:
- Clustered rural settlements are commonly found in fertile alluvial plains and regions with high agricultural productivity.
- Linear settlements usually develop along rivers, roads, or canals, especially in hilly or coastal areas.
- Dispersed settlements are typically found in arid and semi-arid regions with frag- mented landholdings and poor agricultur- al productivity.
How many of the above statements are cor- rect?
Correct
Answer: (c)
Explanation:
- Statement 1 is correct: Clustered (or Nucleated) settlements are characterized by a compact or closely built-up area of houses. These are most common in the fertile alluvial plains (like the Indo-Gangetic Plain) and the Northeast. The high agricultural productivity supports a dense population, and the need for security or communal living often encourages people to live close together.
- Statement 2 is correct: Linear settlements occur when houses are built along a specific line of communication or a natural feature. You will typically see these along roads, railway lines, rivers, or canal banks. In coastal areas (like Kerala) or narrow mountain valleys, the lack of wide flat land forces people to settle in long, thin strips.
- Statement 3 is correct: Dispersed (or Isolated) settlements appear as a few isolated huts or small hamlets. These are typical of arid/semi-arid regions (Rajasthan), hilly terrains (Himalayas), or thickly forested areas. In these regions, the land is fragmented, and resources (like water or fertile patches) are spread thin, making large, concentrated villages difficult to sustain.

Question 7 of 15
7. Question
1 pointsConsider the following statements regarding AgriStack:
- It aims to create a digital ecosystem of farmer and farm-related data, integrating land records and other agricultural datasets.
- One of its objectives is to facilitate credit-on-tap and targeted delivery of agricultural services to farmers using digital records.
- The initiative is implemented by the Ministry of Electronics and Information Technology (MeitY).
Which of the statements given above is/are correct?
Correct
Answer: (a)
Explanation:
- Statement 1 is correct: AgriStack is a collection of digital databases and services. Its core is the Farmer ID (similar to Aadhaar for farmers), which is linked to digitized land records. By integrating data on crops, soil health, and land ownership, it creates a single source of truth for the agricultural ecosystem.
- Statement 2 is correct: One of the most significant hurdles for farmers is Information Asymmetry when applying for loans. AgriStack allows banks to verify a farmer’s landholding and crop history instantly. This facilitates credit-on-tap (faster, paperless loans) and ensures that government subsidies (like PM-KISAN or crop insurance) reach the intended beneficiary without leakages.
- Statement 3 is incorrect: While AgriStack is a high-tech digital initiative, it is implemented by the Ministry of Agriculture and Farmers Welfare. Although it receives technical support from other departments, the policy and data ownership lie with the Agriculture Ministry.

Question 9 of 15
9. Question
1 pointsWith reference to the ‘Asiatic Lion’ (Panthera leo persica), consider the following statements:
- It is currently classified as Critically Endangered on the IUCN Red List of Threatened Species.
- It is protected under Schedule I of the Wildlife Protection Act, 1972, and listed in Appendix I of CITES.
- The species is found in the wild only in the Gir landscape of Gujarat, India.
Which of the statements given above are correct?
Correct
Answer: (b)
Explanation:
- Statement 1 is incorrect: While the Asiatic Lion was long classified as ‘Endangered’, its status on the IUCN Red List was recently updated to ‘Vulnerable’. This reclassification is a result of the steady increase in its population over the last decade, although it still remains susceptible to threats like disease and habitat fragmentation.
- Statement 2 is correct: Due to its limited population and high conservation value, it receives the highest level of legal protection in India under Schedule I of the Wildlife Protection Act, 1972. Internationally, it is listed in Appendix I of CITES, which strictly prohibits its international commercial trade.
Statement 3 is correct: The Asiatic Lion is endemic to the Gir landscape in Gujarat. It is the only place in the world where this subspecies exists in the wild. This single-population status is a major point of concern for biologists, as a single localized disaster or epidemic could wipe out the entire species.

Question 10 of 15
10. Question
1 pointsWith reference to the contributions of Mahatma Jyotiba Phule, consider the following statements:
- He founded the ‘Satyashodhak Samaj’ in 1873 to promote social justice and oppose Brahmanical dominance.
- In his work ‘Gulamgiri’, he drew a parallel between the caste-based oppression in India and the racial slavery prevalent in the United States.
- He was a contemporary of Raja Ram Mohan Roy and collaborated with him to establish the Brahmo Samaj in Maharashtra.
Which of the statements given above are correct?
Correct
Answer: (a)
Explanation:
- Statement 1 is correct: In September 1873, Jyotirao Phule formed the Satyashodhak Samaj (Society of Seekers of Truth). Its primary mission was to liberate the Shudras and Ati-Shudras from exploitation by Brahmins and to promote social rights and political access for the oppressed classes.
- Statement 2 is correct: Phule’s seminal work, Gulamgiri (published in 1873), is dedicated to the American movement to free slaves. He drew a direct historical and moral parallel between the condition of the lower castes in India and the Black slaves in America, using the comparison to argue that caste was a form of slavery imposed by Aryan invaders.
Statement 3 is incorrect: Raja Ram Mohan Roy died in 1833, while Jyotirao Phule’s active public life began in the late 1840s. Furthermore, the Brahmo Samaj was a Bengali reform movement; while it influenced others, Phule’s movement was indigenous to Maharashtra and focused more on the Bahujan (masses) rather than the upper-caste intellectual reform favored by the early Brahmo Samaj.

Detailed Solution:
- Option (a) is incorrect: The passage says the divide is increasingly about the quality, implying access is one factor, not necessarily the primary or only determinant.
- Option (b) is correct: This is the core message. The author argues that having the infrastructure (mobile penetration/access) isn’t enough; without quality and literacy (the ability to leverage tools), the divide remains.
- Option (c) is incorrect: The passage does not compare high-end computing to mobile technology; it critiques how the existing technology (mobiles) is being used.
- Option (d) is incorrect: This contradicts the passage. The author suggests digital literacy is crucial to help people move from consumption to productive use.
