1.Read the following passage carefully :
Unfortunately the chances of any animal becoming a fossil are not very great, and the chances of a fossil then being discovered many thousands of years later are even less. It is not surprising that of all the millions of animals that have lived in the past, we actually have fossils of only a very few.
There are several ways in which animals and plants may become fossilized. First, it is essential that the remains are buried, as dead animals and plants are quickly destroyed if they remain exposed to the air. Plants rot, while scavengers, such as insects and hyenas, eat the flesh and bones of animals. Finally the few remaining bones soon disintegrate in the hot sun and pouring rain. If buried in suitable conditions, however, animal and plant remains will be preserved. The same chemicals which change sand and silt into hard rock will also enter the animal and plant remains and make them hard too. When this happens we say that they have become fossilized. Usually only the bones of an animal and the toughest part of a plant are preserved
