QUESTION: 157

In some cities, many potters have been winning acclaim as artists. But since pottery must be useful, potters must exercise their craft with an eye to the practical utility of their product. For this reason, pottery is not an art.

Which of the following, is an assumption that supports drawing the conclusion above from the reason given for that conclusion?

Some plates, bowl and vessels are made to be placed in museums where they will not be used by anyone.
Some potters are more concerned than others with the practical utility of the products they produce.
Potters should be more concerned with the practical utility of their products than they currently are.
Artists are not concerned with the monetary value of their products.
An object is not an art object if its maker pays attention to the objects’ practical utility.

Answer(s): E

Explanation:

The best answer is E. The argument concludes that pottery is not an art because potters must consider the practical utility of their product. If it is true that an object is not a work of art if its maker pays attention to the objects practical utility, the conclusion is supported.

QUESTION: 158

Activity levels of the green iguana vary in cycles that are repeated every 24 hours. It is logical to assume that alteration in the intensity of incident light is the stimulus that controls these daily biological rhythms. But there is much evidence to contradict this hypothesis.

Which of the following, if known, is evidence that contradicts the hypothesis stated above?

The temperature of the green iguana varies throughout the day, with the maximum occurring in the late afternoon and the minimum in the morning.
While some animals, such as the rabbit, are much more active during the day, others, such as moles, show greater activity at night.
When animals are transported from one time zone to another, their daily biological rhythms adjust in a matter of days to the periods of sunlight and darkness in the new zone.
Other types of iguanas display similar activity cycles even though they live in very different climates.
Even when exposed to constant light intensity around the clock, some iguanas display rates of activity that are much greater during daylight hours than at night

Answer(s): E

Explanation:

The best answer is E. If iguanas that are exposed to light 24 hours a day display a similar pattern of activity as those exposed to natural light and dark cycles this constitutes evidence again the hypothesis that it is the alterations in light that control biological cycles.

QUESTION: 159

Researchers recently discovered that lipstick can become contaminated with bacteria that causes mononucleosis. They found that contamination usually occurs after the lipstick has been used for six months. For that reason, women should dispose of any lipstick after six months of use.

Which of the following, if true, would most weaken the conclusion above?

The researchers could not discover why lipstick contamination usually occurred only after six months of use.
The researchers failed to investigate contamination of lipstick by viruses, yeasts, and other pathogenic microorganisms.
The researchers found that among women who used lipstick contaminated with bacteria that causes mononucleosis, the incidence of these diseases was no higher than among people who used uncontaminated lipsticks.
The researchers found that people who wiped their lipsticks clean after each use were as likely to have contaminated lipsticks as were people who never wiped their lipsticks.
The researchers found that, after six weeks of use, greater length of use of a lipstick did not correlate with a higher number of bacteria being present.

Answer(s): C

Explanation:

The best answer is C. According to choice C, using a contaminated lipstick does not increase the incidence of infection, so the recommendation to replace a lipstick before it becomes contaminated is greatly undermined.

QUESTION: 160

Unlike the wholesale price of uncut diamonds, the wholesale price of other uncut gemstones has fallen considerably in the last year. Thus, although the retail price of jewelry made with gemstones other than diamonds has not yet fallen, it will inevitably fall.

Which of the following, if true, most seriously weakens the argument above?

The cost of processing uncut gemstones has increased during the last year.
The wholesale price of uncut diamonds is typically higher than that of the same volume of other uncut gemstones.
The operating costs of the average retail jewelry store have remained constant during the last year.
The cost of mining gemstones other than diamonds has increased in the last year.
Changes in retail prices always lag behind changes in wholesale prices.
