Read the following paragraph and then answer the questions. There are several ways that recording companies and artists themselves can create successful music careers. Both recording companies and individual artists can make high-quality recordings available to consumers, usually in the form of tapes and CDs. In addition, recording companies provide promotion of these works; likewise, an individual artist wants to promote his or her own work as much as possible. Just as a recording company will advertise an artist’s recordings to as large an audience as possible and sometimes provide promotional tours, an artist will also try to do the same when working on his or her own. In addition, a recording company will sell the music it records for a profit and give a percentage of that money to the artist in payments known as royalties; similarly, an artist will try to sell his or her own work for profit. Thus, there are several things that both recording companies and individual artists will do in order to try to establish their work in the industry.

Passage B--Effects of Noise In general, it is plausible to suppose that we should prefer peace and quiet to noise. And yet most of us have had the experience of having to adjust to sleeping in the mountains or the countryside because it was ‘too quiet', an experience that suggests that humans are capable of adapting to a wide range of noise levels. Research supports this view. For example, Glass and Singer (1972) exposed people to short bursts of very loud noise and then measured their ability to work out problems and their physiological reactions to the noise. The noise was quite disruptive at first, but after about four minutes the subjects were doing just as well on their tasks as control subjects who were not exposed to noise. Their physiological arousal also declined quickly to the same levels as those of the control subjects. But there are limits to adaptation and loud noise becomes more troublesome if the person is required to concentrate on more than one task. For example, high noise levels interfered with the performance of subjects who were required to monitor three dials at a time, a task not unlike that of a pilot or that of an air-traffic controller (Broadbent, 1957). Similarly, noise did not affect a subject's ability to track a moving line with a steering wheel, but it did interfere with the subject's ability to repeat numbers while tracking (Finkelman and Glass, 1970). Probably the most significant finding from research on noise is that its predictability is more important than how loud it is. We are much more able to ‘tune out' chronic background noise, even if it is quite loud, than to work under circumstances with unexpected intrusions of noise. In the Glass and Singer study, in which subjects were exposed to bursts of noise as they worked on a task, some subjects heard loud bursts and others heard soft bursts. For some subjects, the bursts were spaced exactly one minute apart (predictable noise); others heard the same amount of noise overall, but the bursts occurred at random intervals (unpredictable noise). Subjects reported finding the predictable and unpredictable noise equally annoying, and all subjects performed at about the same level during the noise portion of the experiment. But the different noise conditions had quite different effects when the subjects were required to proofread written material under conditions of no noise, as shown in Table 1. Table 1: Proofreading Errors and Noise Unpredictable Predictable Average Noise Noise Loud noise 40.1 31.8 35.9 Soft noise 36.7 27.4 32.1 Average 38.4 29.6 7.
