Read the following passage and answer the questions given at the end :
There are three main groups of oil : animal, vegetable and mineral Great quantities of animal oil
come from whales, those enormous creatures of the sea which are the largest remaining animals
in the world. To protect the whale from the old of the Arctic seas, nature has provided it with
a thick covering of fat called blubber. When the whale is lilled, the blubber is stopped off and
boiled down, either on board ship or on shore. I produces the quantity of oil which can be
made into food for human consumption. A few other creatures yield oil, but none 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 liver oil are given to sick children and other invalids who need certain vitamins.
These oils may be bought at any chemist's
Vegetable oil has been known from antiquity. No household can get on withour it, for it is used
in cooking. Perfumes may be made from the oils of certain flowers. Soaps are made from vegetable
and animals oils.
To the ordinary man, one kind of oil may be as important as another. But when a politician or
an engineer refers to oil, he almost always means mineral oil, the oil that drives tanks, aeroplanes
and warships, motor cars and diesel locomotives; the oil that is used to lubricate all kinds of
machinery. This is the oil that has changed the life of the common man. When it is refined into
petrol, it is used to drive the internal-combustion engine. To it we owe the existence of the motor
car, which has replaced the private carriage drawn by the horse. To it we owe the possibility of
flying. It has changed the methods of warfare on land and sea. This kind of oil comes out of the
carth. Because it burns well, it is used as fuel and in some ways it is superior to coal in this respect.
Many big ships now burn oil instead of coal. Because it burns brightly, it is used for illumination;
countless homes are still illuminated with oil-burning lamps. Because it is very slippery, it is used
for lubrication.
