Q18easyPartial Truth
Consider the following statements:
Once the Central Government notifies an area as a 'Community Reserve'
1. the Chief Wildlife Warden of the State becomes the governing authority of such forest
2. hunting is not allowed in such area
3. people of such area are allowed to collect non-timber forest produce
4. people of such area are allowed traditional agricultural practices
How many of the above statements are correct?
(a) Only one
(b) Only two
(c) Only three
(d) All four
Answer: (b)
Trap: Partial Truth
Statement 1 is a trap -- Community Reserves are managed by a Community Reserve Management Committee, not the Chief Wildlife Warden (who oversees but isn't the governing authority). Statement 4 may seem logical (community involvement) but is not a blanket provision. Aspirants tend to over-assume community rights in Community Reserves.
Q22easyAbsolute Qualifier
Consider the following statements:
Statement-I: Marsupials are not naturally found in India.
Statement-II: Marsupials can thrive only in montane grasslands with no predators.
Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
(c) Statement-1 is correct but Statement-II is incorrect
(d) Statement-1 is incorrect but Statement-II is correct
Answer: (c)
Trap: Absolute Qualifier
Statement-II uses the absolute qualifier 'only in montane grasslands with no predators.' Marsupials thrive in diverse habitats across Australia, including forests, deserts, and urban areas, alongside predators. The absolute claim makes it false. Aspirants may accept it as a plausible ecological explanation.
Q23moderate
'Invasive Species Specialist Group' (that develops Global Invasive Species Database) belongs to which one of the following organizations?
(a) The International Union for Conservation of Nature
(b) The United Nations Environment Programme
(c) The United Nations World Commission for Environment and Development
(d) The World Wide Fund for Nature
Answer: (a)
Q24easyCommon Misconception
Consider the following fauna:
1. Lion-tailed Macaque
2. Malabar Civet
3. Sambar Deer
How many of the above are generally nocturnal or most active after sunset?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (a)
Trap: Common Misconception
Sambar Deer (option 3) is the trap. While Sambar Deer can be active at dawn/dusk (crepuscular) and occasionally at night, they are not primarily nocturnal. Lion-tailed Macaques are diurnal (active during day). Only the Malabar Civet is truly nocturnal. Aspirants may think civets and deer are both nocturnal.
Q25easy
Which of the following organisms perform waggle dance for others of their kin to indicate the direction and the distance to a source of their food?
(a) Butterflies
(b) Dragonflies
(c) Honeybees
(d) Wasps
Answer: (c)
Q27moderateCommon Misconception
Consider the following statements regarding the Indian squirrels:
1. They build nests by making burrows in the ground.
2. They store their food materials like nuts and seeds in the ground.
3. They are omnivorous.
How many of the above statements are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (b)
Trap: Common Misconception
Statement 1 is the trap. Indian squirrels (palm squirrels, giant squirrels) build nests (dreys) in trees, NOT by burrowing in the ground. Ground squirrels burrow, but Indian tree squirrels build arboreal nests. Aspirants may confuse Indian squirrels with ground squirrels.
Q30moderateDistractor Pairing
Consider the following:
1. Aerosols
2. Foam agents
3. Fire retardants
4. Lubricants
In the making of how many of the above are hydrofluorocarbons used?
(a) Only one
(b) Only two
(c) Only three
(d) All four
Answer: (c)
Trap: Distractor Pairing
Option 4 (Lubricants) is the trap. HFCs are used in aerosols, foam blowing agents, and fire extinguishing agents, but lubricants typically use mineral oils, synthetic oils, or greases -- not HFCs. Aspirants who over-generalize HFC applications may include lubricants.
Q42moderateScope Confusion
Consider the following statements:
Statement-I: Carbon markets are likely to be one of the most widespread tools in the fight against climate change.
Statement-II: Carbon markets transfer resources from the private sector to the State.
Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
(c) Statement-I is correct but Statement-II is incorrect
(d) Statement-I is incorrect but Statement-II is correct
Answer: (a)
Trap: Scope Confusion
Statement-II is the contentious part. Carbon markets can involve both private-to-state transfers (carbon tax/auctioned permits) and private-to-private transfers (voluntary carbon trading). The official answer treats Statement-II as correct, viewing carbon markets as a mechanism that channels resources to the state through permit auctions/taxes. Aspirants may choose (c) thinking carbon markets are purely market-based.
Q77easyAbsolute Qualifier
Consider the following activities:
1. Spreading finely ground basalt rock on farmlands extensively
2. Increasing the alkalinity of oceans by adding lime
3. Capturing carbon dioxide released by various industries and pumping it into abandoned subterranean mines in the form of carbonated waters
How many of the above activities are often considered and discussed for carbon capture and sequestration?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (a)
Trap: Absolute Qualifier
The official answer (a) suggests only one activity qualifies. However, all three are discussed as carbon sequestration methods: enhanced rock weathering (1), ocean alkalinity enhancement (2), and mineral carbonation in mines (3). The official answer is widely disputed -- most experts believe (c) is correct.
Q88moderateCommon Misconception
Consider the following statements regarding mercury pollution:
1. Gold mining activity is a source of mercury pollution in the world.
2. Coal-based thermal power plants cause mercury pollution.
3. There is no known safe level of exposure to mercury.
How many of the above statements are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (d)
Trap: Common Misconception
The official answer (d) 'none correct' is widely disputed. All three statements are factually correct: artisanal gold mining uses mercury amalgamation (1), coal plants emit mercury (2), and WHO states no safe level of mercury exposure exists (3). Most experts believe (c) All three is correct.
Q98easyPartial Truth
Consider the following statements:
1. In India, the Biodiversity Management Committees are key to the realization of the objectives of the Nagoya Protocol.
2. The Biodiversity Management Committees have important functions in determining access and benefit sharing, including the power to levy collection fees on the access of biological resources within its jurisdiction.
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
Answer: (d)
Trap: Partial Truth
Both statements sound plausible. BMCs do play a role in biodiversity management, and the Nagoya Protocol deals with Access and Benefit Sharing. However, the official answer (d) suggests neither is correct. BMCs have an advisory role and prepare People's Biodiversity Registers, but access and benefit-sharing decisions are made by the National/State Biodiversity Boards, not BMCs. BMCs cannot independently levy fees.
Q100moderateAbsolute Qualifier
Consider the following statements:
Statement-I: Namami Gange Mission is under the Ministry of Jal Shakti.
Statement-II: All the River Conservation Projects come under the purview of the National Mission for Clean Ganga.
Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
(c) Statement-I is correct but Statement-II is incorrect
(d) Statement-I is incorrect but Statement-II is correct
Answer: (a)
Trap: Absolute Qualifier
The trap is choosing (c). Statement-II sounds too broad -- 'ALL river conservation projects' under NMCG? Aspirants may doubt this. However, the National River Conservation Plan was indeed merged with NMCG in 2016, bringing most river conservation projects under its purview, and NMCG is under the Ministry of Jal Shakti. So both are correct and Statement-II explains why Namami Gange is under that ministry.
