PART FOUR WRITING
SECTION A
Directions: Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN 3 WORDS for each answer.
Supplying energy by nuclear power is a new trend in the recent years. However, it may be very dangerous.
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely, road and rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is a problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these waste non radioactive, so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the area. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it doesn’t provide a serious objection to nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.
