• Question 1 of 5 1. Question Consider the following statements regarding the Standing Committee on Economic Statistics (SCES): SCES was established by the Ministry of Finance. The committee focuses primarily on advising survey methodology and finalizing survey tabulation plans. SCES is a permanent committee tasked with providing oversight on economic statistics. How many of the above statements is/are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A Only Statement 2 is correct. The Standing Committee on Economic Statistics (SCES) was established in 2019 by the Ministry of Statistics and Programme Implementation (MoSPI), not the Ministry of Finance, making Statement 1 incorrect. The committee plays a crucial role in providing guidance on survey methodology, including sampling design, survey instruments, and tabulation plans, which makes Statement 2 correct. However, Statement 3 is incorrect because SCES is not a permanent body; it was formed to address specific statistical issues and does not function as a continuous oversight mechanism. The committee primarily works on improving economic surveys such as those related to employment, consumption, and enterprises. Incorrect Solution: A Only Statement 2 is correct.

• Question 3 of 5 3. Question Consider the following statements regarding bio-plastics: Bio-plastics are always biodegradable and compostable. Bio-plastics are derived from renewable biomass sources like corn starch and sugarcane. Bio-plastics help reduce the dependency on fossil fuels for plastic production. How many of the above statements is/are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Bio-plastics are plastics derived from renewable biomass sources such as corn starch, sugarcane, and vegetable oils, making Statement 2 correct. They are considered an alternative to conventional plastics as they help reduce dependency on fossil fuels, which supports Statement 3. However, Statement 1 is incorrect because not all bio-plastics are biodegradable or compostable. Some bio-plastics, although derived from renewable sources, have chemical properties similar to conventional plastics and can persist in the environment for long periods. Examples include bio-based polyethylene (bio-PE), which is made from renewable resources but is not biodegradable. On the other hand, some bio-plastics like polylactic acid (PLA) and polyhydroxyalkanoates (PHA) are biodegradable under specific industrial conditions.

• Question 4 of 5 4. Question Teal carbon refers to carbon stored in which of the following ecosystems? (a) Grasslands and savannas (b) Tropical rainforests (c) Freshwater wetlands (d) Mangroves and coastal wetlands Correct Solution: C Teal carbon refers to carbon stored in non-tidal freshwater wetlands, such as marshes, peatlands, and inland swamps. These ecosystems play a crucial role in carbon sequestration by trapping carbon in vegetation, microbial biomass, and organic-rich sediments. Unlike blue carbon, which is associated with tidal and marine ecosystems like mangroves and seagrasses, teal carbon focuses on freshwater wetland systems. These wetlands act as carbon sinks, helping regulate greenhouse gases (GHGs) and mitigate climate change by storing carbon for long periods. However, when disturbed, they can release large amounts of carbon dioxide (CO₂) and methane (CH₄) into the atmosphere.

How many of the above statements is/are incorrect? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A Keoladeo National Park, also known as Bharatpur Bird Sanctuary, is located in Bharatpur, Rajasthan, and is recognized as a UNESCO World Heritage Site due to its rich biodiversity and significance as a bird habitat, making Statement 1 correct. Statement 2 is incorrect because Keoladeo National Park, along with Chilika Lake, was declared India’s first Ramsar Site in 1981, not Vembanad Lake. Vembanad Lake in Kerala is also a Ramsar site but was not among the first designated ones. Statement 3 is correct, as the Gambhir and Banganga rivers provide essential water sources that support the wetland ecosystem of the park, making it an important breeding ground for migratory birds, including the rare Siberian crane.
