Answer:
Without oil the modern world could not exist. Oil is needed for travel, because it powers our motor cars,
buses, trains, aeroplanes and ships. Oil helps machines of all kinds, to run easily. Oil also gives us other
substances, such as artificial rubber, artificial materials for clothing, and new materials for making things. Yet
till a hundred years ago no one used oil for any of these purposes. In fact, no one knew that much oil existed.
2. Men do not make oil; they find it. They look for oil in many ways. They begin by making a map of the land
where they are searching. Then they use the map to help them in choosing a site to explore with more care.
They start their work by examining the rock from under the surface and come to know whether oil is likely to
be underneath the rock.
