Where was the first world summit on social development under the aegis of UNESCO held?

The correct answer is D) Copenhagen. The World Summit for Social Development was held in Copenhagen in March 1995. It adopted the Copenhagen Declaration on Social Development and a Programme of Action that put poverty eradication, full employment and social integration at the centre of development policy.

One correction on the question itself: the summit was convened under the United Nations, not UNESCO. UNESCO works on education, science and culture, so the premise is wrong, but the city is still Copenhagen. Do not let the wrong agency push you towards Paris, which is UNESCO's headquarters and the obvious distractor.

Why the others fail: London has no link to this summit. New York hosts UN headquarters and many later UN meetings, which is why it tempts candidates, but this summit was not held there. Paris is merely UNESCO's seat, and choosing it depends entirely on the faulty premise.

Core concept: social development as a UN agenda, born out of the 1990s global conferences on population, environment and women. For Mains, it connects to inclusive growth and the 20:20 compact, which encouraged countries to commit funding to basic social services.

Trap: picking Paris because of the UNESCO link. Fix the sponsor in your mind as the UN and the city as Copenhagen.
