UPSC Civil Services Model Paper 4

Lignite is low-grade brown coal, which is soft with high moisture content.
Coal that has been buried deep and subjected to increased temperatures is bituminous coal.
Metallurgical coal is high-grade bituminous coal which has a special value for smelting iron in blast furnaces.
Anthracite is the highest quality of hard coal.
So, high-grade coal should be hard with less moisture and greater carbon content, and not the opposite.
So, statement 1 and 2 are NOT correct.
