Such intellectually challenging (rather, challenged!) questions would gradually be out of vogue from the competitive examinations being conducted to recruit Lord Thomas Babington Macaulay's clerks of various ilk in both India and Bangladesh.
This Island has disappeared into the sea!
New Moore Island (a.k.a. Purbasha in India and South Talpatti in Bangladesh) was an island of about 3 x 3 km area situated in the Bay of Bengal off the coast of the India and Bangladesh. It is an uninhabited piece of sandy island, formed as a result of silt deposition from both the Ganga and the Brahmaputra over centuries. It peeped out of the sea after a cyclone in 1970. Since then, both India and Bangladesh have been claiming sovereignty over the island as there was a speculation of oil and natural gas beneath the surface, which was never to be found. The Government of India hoisted the national flag in 1981 and established a temporary military base with our warships frequenting every now and then. It became a contentious issue and was having an important mention in the Indo-Bangla bilateral talks between various External Affairs Ministers and Prime Ministers of both the countries during the last four decades. The Radcliffe Award and the mid-channel flow principle (a.k.a. Thalweg Doctrine) were analysed threadbare by the bureaucrats serving at the External Affairs and Home Ministries of both the countires.
And out of the blue, before the problem could be bilaterally resolved and an amicable solution could be worked out, the Island itself has vanished into the sea! It happened a few weeks ago. Scientists of various universities across the globe have brainstormed the issue and have discovered that global warming resulting in the rise of mean sea level is the prime accused which has led to the unfortunate submergence of this Island. Before closing the respective files on this Island, the bureaucrats of both the countries would be drafting certain order sheet and file notings. That would be one of the most amusing documents written in the history of human civilisation!
