There are three separate sources of hazard ithe process of supplying energy by nuclear

power. The radioactive material must travel from its place of manufacture at the power station.
Although the power stations themselves are solidly built, the containers used for the
transport of the materials are not. There are normally only two methods of transport available,
namely road or rail. Unfortunately, both of these involve close contact with the general public,
since the routes are sure to pass near, or even through, heavily populated areas.
Next, there is the problem of waste. All nuclear power stations produce wastes that
in mostcases will remain radioactive for thousands of years. It is impossible to make these
wastes non radioactive, and so they must be stored in one of the inconvenient ways that
scientists have in vented. For example they may be buried under the ground, or dropped into
abandoned mines, or sunk in the sea. However, these methods do not solve the problem, since
an earthquake could easily crack the containers open.
Finally, there is the problem of accidental exposure due to a leak or an explosion at
the power station. As with the other two hazards, this is not every likely, so it does not provide a
serious objection to the nuclear program. Nevertheless, it can happen.
Separately, these there types of risks are not a great cause for concern. On the whole
though, the probability of disaster is still high

Among the various effects of air pollution climatic change are slow, the deterioration of
health is insidious, and the damage to plants, animals, or materials seems remote to those not
directly involved. But smoke is visible to all, and the stinks of sulfides are all over. As a
result, most complaints by individuals to air pollution agencies refer to something that can be
seen or smelled.

6. What is the main idea of the paragraph?

A. The effect of air pollution on people's lives can be direct and indirect.
B. People are not directly affected by the damage of plant and animals.
C. People complain about all the pollutants in the air.
D. Climatic change does not immediately have an effect on people's lives.
E. Complaints by individuals have been made to pollution agencies.

7. The main information about at the paragraph is .

A. the danger of air pollution
B. the slow climatic change
C. the effects of air pollution
D. wastes emitted by air pollution
E. complaints about air pollution

Both the sun and the moon appear larger when they are rising or setting, although the are is no
real difference in the distance they are from the earth. This perceptional phenomenon, known as
the "Moon illusion." has been studied over, the years. Various explanations, including the
muscle strain for the person looking up and the comparison of the moon with other things on the
horizon that make it appear larger, have been disputed by scientists, but thus far there is no
widely accepted explanation of the phenomenon.
8. What is at the topic of the passage?
A. Perceived sizes of the sun and moon
B. Comparison of objects on the horizon
C. Perceptions of distance
D. The rising and the setting of the sun and the moon
E. The "Moon illusion"

9. Which of the following statements is TRUE about the "Moon illusion"?

A. Through various experiments scientists discovered the causes of "Moon illusion". .
B. Although the phenomenon has been studied for years, scientists don't agree about its
cause.
C. The already known distance of the sun and moon from the earth explains the "Moon
illusion".
D. All the answers to at the question of what causes , the phenomenon are the same.
E. Scientists do not think that the mystery of at the "Moon illusion" can be solved.

In canning, heat can be used to destroy bacteria and halt enzymic activity in food. Bacterial
10 from external sources is prevented by sealing the food in a can. The can is the heated to a
temperate 11 to sterilize the contents. The length of time and the temperature 12 to ensure
sterilization depend on the product and on the type of bacteria to b,e destroyed. It is
important .that the contents of the can are heated 13 An experimental check can be made on
the exact temperature in any part of a sample can 14 it is being heated by inserting a there
couple into the can.
