Soal UMPTN 2012

Text I
 There are three separate sources of hazard in the 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 most cases 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.
The whole text tells us about __.
A.  the danger of transporting radioactive materials
B.  the way to make radioactive wastes not dangerous for people
C.  the potential dangers in suppling energy by nuclear power
D.  the accidents caused by nuclear power stations
E.  people's objections to the establishment of nuclear stations
What makes the transported of radioactive materials dangerously for people's lives?
A.  The road
B.  The containers
C.  The rail
D.  The power station
E.  The heavily populated areas

Which of the following statement is TRUE about radioactive wastes?
A.  There will be no more danger when radioactive wastes are buried underground.
B.  There is no chance of saving people's lives from radioactive wastes.
C.  Radioactive wastes become non-radioactive when they are sunk in the sea.
D.  Only earthquakes can change radioactive wastes into non-radioactive wastes.
E.  Natural disasters may cause very serious leaks in buried containers of radioactive wastes.

In spite of the problems which are likely at occur in supplying energy by nuclear power, the writer thinks that
A.  people will strongly object to it
B.  the probability of disaster is high
C.  hazards should be rigidly controlled
D.  it's worth conducting nuclear programs
E.  there is a great cause for concern

We may conclude from the third paragraph that the problem of accidental exposure is caused by __.'
A.  human error
B.  an earthquake
C.  radioactive wastes
D.  hazards
E.  bad design of the nuclear station

Text II
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.

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.

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
