Q1Under the National Air Quality Monitoring Programme, which sequence correctly shows the proposed increase in manual ambient-air monitoring stations by FY 2025-26?
The cited proposal under the National Air Quality Monitoring Programme was to increase manual ambient-air monitoring stations from 818 to 1,936 by FY 2025-26. The figures 1,340 and 489 relate to the wider monitoring network and city coverage in another data point, while 818 to 1,340 does not state the proposed FY 2025-26 target.
Q2Which statement correctly identifies the launch of the National Clean Air Programme (NCAP)?
The cited PIB release says NCAP was launched by the Ministry of Environment, Forest and Climate Change in January 2019 as a national-level strategy for prevention, control and abatement of air pollution. NITI Aayog, the Ministry of Housing and Urban Affairs, and the Central Pollution Control Board do not match the launching ministry and mandate stated in the cited fact.
Q3Match the NCAP prescription for million-plus cities and urban agglomerations with the correct details: List I 1. Covered subset 2. Annual target 3. Good Days definition 4. Air quality threshold List II a. 15% improvement b. Air Quality Index below 200 c. 49 million-plus cities and urban agglomerations d. Good Days Choose the correct code.
The correct matching is: the covered subset is 49 million-plus cities and urban agglomerations; the annual target is 15% improvement; the metric is Good Days; and Good Days are defined by an Air Quality Index below 200. Pairing the 15% figure with the subset, treating the AQI threshold as the target itself, or making Good Days the subset reverses the cited prescription.
Q4With reference to Vapour Recovery Systems at petrol pumps, consider the following statements: 1. They are required at new and existing petrol pumps selling gasoline above 100 kilolitres per month in million-plus cities. 2. They are required at petrol pumps selling gasoline above 300 kilolitres per month in cities with population between 1 lakh and 10 lakh. 3. The same 100 kilolitres per month threshold applies uniformly to all cities with population above 1 lakh. Which of the statements given above are correct?
Statement 1 is correct because the cited measure requires Vapour Recovery Systems at new and existing petrol pumps selling gasoline above 100 kilolitres per month in million-plus cities. Statement 2 is correct because the threshold is above 300 kilolitres per month in cities with population between 1 lakh and 10 lakh. Statement 3 is wrong because the threshold is not uniform across these city categories.
Q5Consider the following assertion and reason about CAQM's 27th Full Commission meeting. Assertion: PM2.5 was identified as the dominant pollutant affecting Delhi's AQI. Reason: The finding came from a meta-analysis covering 2015-2025 reviewed at the meeting on 20 February 2026.
The Assertion is true because PM2.5 was identified as the dominant pollutant affecting Delhi's AQI. The Reason is also true because the cited expert review was a 2015-2025 meta-analysis discussed at the 27th Full Commission meeting on 20 February 2026. That review is the stated basis for the PM2.5 finding, so it explains the Assertion. The alternatives that deny the finding, deny the review period, or separate the review from the finding do not match the cited fact.
