How many pollution hotspots have been identified in Delhi under the air pollution mitigation plan reviewed recently?

The correct answer is 500. The rule denies fuel to a vehicle that has no valid pollution under control certificate, and it is to be applied in mission mode through a city-wide awareness and enforcement campaign at every fuel station equipped with automatic number plate recognition, of which there are five hundred. Pumps that fail to apply the rule will face action. The options of two hundred and fifty, three hundred and fifty and seven hundred and fifty are all wrong because they do not match the count of camera-enabled stations named in the plan. Other transport measures cleared at the same meeting include a campaign for the Delhi Metro Sarthi App and last-mile connectivity at all 228 Metro stations.

The correct answer is 5,088. Delhi's bus fleet has grown to six thousand eight hundred and forty vehicles in all, and of these five thousand and eighty-eight run on electricity, which makes electric buses the larger part of the fleet. The option of six thousand eight hundred and forty is the trap here: that is the size of the whole fleet, not the count of electric buses alone, so a candidate who reads the question quickly is likely to pick it. The options of three thousand four hundred and twenty and four thousand two hundred are wrong because neither figure appears in the plan. Promoting public transport was listed among the measures, along with last-mile connectivity at every Metro station.

The correct answer is 20 to 25 participants, a cap the zoo keeps so that each walk stays a close and useful learning exercise rather than a crowd. Options A, C and D do not match the limit set for these walks. Registration beforehand is compulsory and is accepted first come, first served through a form that stays open from Monday to Friday every week, with the link put up on the official website of the National Zoological Park and on the NZP Sathi mobile application. Note the distinction between this cap and the turnout at the walk being reported, which was fifteen participants. For Wildlife Week the zoo has invited school students from government and private schools across Delhi-NCR, and charges no fee for any activity.

The correct answer is the Ministry of Environment, Forest and Climate Change, the ministry that handles wildlife and biodiversity matters and under which the National Zoological Park works. Option B deals with farming and allied activities, option C with museums, academies and heritage institutions, and option D with travel and destination promotion, so none of them is the parent ministry of the zoo. The zoo's Director is Dr Sanjeet Kumar, who told participants that nature walks build field identification skills, improve understanding of food webs and add to biodiversity records. For the examination, tie the zoo to this ministry, to the citizen science walks held on Sundays, and to Wildlife Week, which it will observe from the second to the eighth of October. Registration for the walks is taken in advance through the NZP Sathi mobile application or the zoo website, on a first come, first served basis.

The correct answer is 47 species, with sightings of more than seven hundred and fifty individual birds during the walk. Options A, B and D are not figures reported from the exercise. Along with the birds, the walkers recorded eight butterfly species, ten dragonfly species and five damselfly species in the walk area, which the zoo treats as evidence of the diversity of odonates and butterflies inside the park. The observations were made between half past six and half past ten in the morning under bird expert Rohit Sharma and butterfly and dragonfly expert Ramver. The zoo describes such walks as citizen science, since ordinary visitors contribute field records that add to biodiversity documentation while learning to identify species themselves. Fifteen participants joined this walk, and the zoo caps each Sunday nature walk at twenty to twenty-five people so the session stays useful.
