IV. Read this passage and choose the best given answer A, B, C or D for each question:
Many people still believe that natural resources will never be used up. Actually, the world’s energy resources are limited. Nobody
knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of
power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil
and gas before it is too late; and nuclear power is the only alternative. However, many people do not approve of using nuclear power
because it is very dangerous.
The most effective thing is that we should use natural resources as economical as possible.
