QUES: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.

QUES: The major agricultural product is rice, which covers about 60% of the country's total cultivated land area. Rice accounts for 97% of total food grain production by weight. Through collaboration with the International Rice Research Institute 52 modern rice varieties were released in the country between 1966 and 1997, helping increase national rice production to 14 million tons in 1987 and to 19 million tons in 1996. By 1988, modern varieties were planted on half of the country's ricelands, including 98 percent of the irrigated areas. In 2008 rice production was estimated at 50 million tons.

What percentage of  the countries's farm-able land is used for the major farming production crop in Burma? 
What is the answer?
ANS: 60%
QUES: The climate of Cork, like the rest of Ireland, is mild and changeable with abundant rainfall and a lack of temperature extremes. Cork lies in plant Hardiness zone 9b. Met Éireann maintains a climatological weather station at Cork Airport, a few kilometres south of the city. It should be noted that the airport is at an altitude of 151 metres (495 ft) and temperatures can often differ by a few degrees between the airport and the city itself. There are also smaller synoptic weather stations at UCC and Clover Hill.
