Read the following passage and circle the letter A, B, C or D to indicate the correct answer to each question.
Some people believe that natural resources will never be used up. In fact, fossil fuels are limited, so we need to use energy economically and develop other sources of power. Alternatives include solar, wind and nuclear power. Nobody knows exactly how much usable fuel will remain in the future.
Some people do not <u>approve of</u> using nuclear power because they worry about serious accidents and radioactive waste. High doses of ionising radiation can cause harm and increase the risk of cancer. Nuclear power therefore requires strict safety measures. The main message is to save energy and consider the benefits and risks of different energy sources.
