Read the following text carefully and answer the questions no. 5 and 6:

Bangladesh is blessed with huge inland open water resources. It has numerous rivers, canals, beels, lakes and vast areas of floodplains. Hakaluki haor is one of the major wetlands of Bangladesh. With a land area of 18.386 hectares. it supports a rich biodiversity and provides direct and indirect livelihood benefits to nearly 1,90,000 people. This haor was declared an Ecologically Critical Area in April 1999 by the government of Bangladesh. Hakaluki is a complex ecosystem, containing more than 238 interconnecting beels and jalmahals. The haor falls under two administrative districts, Maulvibazar and Sylhet. Some 1,90,000 people live in the area surrounding the haor.

The haor is a very important resting place for migratory waterfowls flying in from the north. The most interesting species is the Barheaded Goose, which is now hardly seen in fresh water wetlands. Many other important species of waterfowls make the haor their temporary home. Unfortunately, illegal poaching has been a threat to the waterfowl population in this vast wetland. Hakaluki haor is known as a good grazing land in winter. People from villages around the haor and also from distant areas send their herds for grazing. During this time, herders make temporary shelters near the beels and graze their animals for a period of 4 to 5 months. The haor had very dense swamp forests in the past, but deforestation and lack of conservation practices have virtually destroyed this unique forest in the last two decades.
