In which year was Buxa declared a Tiger Reserve?

The correct answer is Valmiki Tiger Reserve, Bihar. The tigress, identified as T138, was moved from Valmiki in Bihar to Buxa in West Bengal after ecological, veterinary and management parameters had been assessed and the laid-down protocols followed, and the Environment Minister thanked the Bihar Chief Minister for the state's support in the translocation. Option A, Manas Tiger Reserve in Assam, is a plausible distractor because a tiger photographed at Buxa by camera traps was matched with a Manas animal, but that was evidence of natural movement across the landscape and not the source of this release. Option C, the Sundarbans, lies in the same state as Buxa and is not mentioned as the source at all. Option D, Kanha, is a well-known reserve of Madhya Pradesh that has no part in this programme. The pairing to remember is Valmiki in Bihar as the source and Buxa in West Bengal as the destination.

The correct answer is about 380 hectares, restored or converted over the past eight years as part of the groundwork for tiger recovery at Buxa. Alongside this, more than 800 chital were released to supplement the prey base, and scientific monitoring has indicated a rising trend in prey abundance, which is why the reserve was judged ready for the first release. Options A and B are close but lower figures of the kind examiners use to test whether a candidate has read the number carefully rather than approximately. Option D confuses two separate figures in the same story, since 800 is the count of chital released into the reserve and not an area of grassland. For revision, attach hectares to the grassland figure and head count to the chital figure, and remember that both belong to the Tiger Augmentation and Recovery Project.

The correct answer is India's Wildlife Week. The release of the tigress in Buxa Tiger Reserve was described as a fitting beginning to Wildlife Week in the country, and it coincided with the start of the phased Tiger Reintroduction Programme for the reserve. Option B, National Forest Martyrs Day, honours those who died protecting forests and wildlife and is a separate observance that has no connection with this release. Option C, World Nature Conservation Day, is an international observance and not the occasion named here. Option D is not an observance at all; a wildlife census is an exercise in counting animals rather than a week marked in the calendar, and the monitoring described for this tigress uses telemetry, camera trapping and field observation to follow one animal. Pair the release with Wildlife Week and with the reserve's first reintroduction phase.

The correct answer is 1917. Speaking at the plantation drive, the minister recalled Gandhi's stay in Champaran in that year and highlighted how Gandhi began efforts towards sanitation and hygiene there, how those efforts became part of a wider mass movement, and how they contributed to addressing the grievances of indigo farmers. Options A and B fall before the Champaran episode the minister described and do not match the year he named. Option D comes after it and belongs to a later phase of the national movement. The minister drew a lesson from Champaran for the present day, saying that cleanliness is a mission of empathy and shared responsibility rather than merely a campaign, and he linked that idea to Swachhata Hi Seva being a people's movement in which every individual has a role.

The correct answer is Ek Ped Maa Ke Naam. The Department of Legal Affairs of the Ministry of Law and Justice organised the drive under that theme on the eve of Gandhi Jayanti, and it formed part of Special Campaign 6 as well as Swachhata Hi Seva 2026. Options A, C and D are plausible-sounding names for plantation or greening drives, but none of them is the theme named for this event. The minister, the law secretary who chairs the centre, and senior officers of the department and the centre planted saplings on the campus together. The programme ended with a pledge to carry on cleanliness work and to promote a greener and more sustainable environment, and the centre's leadership tied that pledge to the wider aims of the Swachh Bharat Mission.
