Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
As more people live closer together, and as they use machines to produce leisure, they find that their leisure, and even their working hours, becomes spoilt by a by-product of their machines namely, noise. Noise is nowadays in the news; it has acquired political status, and public opinion is demanding, more and more insistently, that something be done about it.
To control noise is to demand much self-discipline(annoyance arises often from lack of common courtesy), a sense of proportion(there is usually a conflict of interest if a noise is to be stopped), the expenditure of money(and it is far more economical to do this early rather than late), and finally, technical knowledge.
Technical difficulties often arise from the subjective-objective nature of the problem. You can define the excessive speed of a motorcar in terms of a pointer reading on a speedometer. But can you define excessive noise in the same way？ You find that with any existing simple "noisy-meter", vehicles, which are judged to be equally noisy, may show considerable difference on the meter.
Though the ideal cure for noise is to stop it at its source, this may in many cases be impossible. The next remedy is to absorb it on its way to the ear.
Domestic noises may perhaps be controlled by forethought and courtesy, and industrial noises by good planning and technical improvement. But if we are going to allow fast motorcycles and heavy lorries to pass continuously through residential and business districts, the community must decide on the control it needs to exercise, for in the long run it has got to pay for it. And if a nation is to take part in modern air transport, it must enter into international agreements on the noise control and here the cost of any real control is to be measured in millions of dollars.
According to the first paragraph, noise is______.

W: I understand. But the privacy act won't permit it.
M: Really？ Maybe you could tell him.
W: Not even then. I can only give a test to the student whose name appears on it. I can't even give it to a family member.
M: That's bad.
W: I think so, too, frankly, but that's the law.
M: Okay. I'll tell Terry, Thanks anyway.
W: You're welcome. Tell him I'll just keep his test here until he feels better and can come in for it himself.
