Q1. Read the following passage and answer the following:-
There are three main groups of oils: animals, vegetable and mineral. Great quantities of
animals oil comes from whales, those enormous creatures of the sea which are the largest
remaining animals in the world. To protect the whale from the cold of the Arctic seas, nature
has provided it with a thick covering of fat called blubber. When the whale is killed, the
blubber is stripped off and boiled down, either on board ship or on shore. It produces a great
quantity of oil which can be made into food for human consumption. A few other creatures
yield oil, but not so much as the whale. The livers of the cod and the halibut, two kinds of
fish, yield nourishing oil. Both cod liver oil and halibut oil are given to sick children and othe
invalids who need certain vitamins. These oils may be bought at any chemist's shop.

used in cooking, Perfumes may be made from the oils of flowers. Soaps are made from
vegetable and animal oil.
