VI. Read the following passage and choose the correct answer (A, B, C or D) to complete the passage.                 When man first appeared on Earth, his greatest source of power was his own strength. As he grew wiser, he learnt to make animals supply power for him. Then many centuries later, he discovered that wind and water were even better power sources than animals. Still later, he found that power from steam, coal, and oil was often even better than these.                 In the latest search for improved living, physicists – scientists who study energy and matter – have been led to the study of the atom. The physicists have found that atomic energy can do such things as supplying electricity, to cities, blasting tunnels through the mountains, running ships and submarines and even providing for space flights.                 Finding ways to make the atom work for us is a new science.
