直接放题了哈～
1.Scientist: In an experiment, dogs had access to a handle they could pull to release food into a nearby enclosure that contained a familiar dog and nothing else, contained an unfamiliar dog and nothing else, or was empty. The dogs typically released more food to the familiar dog than to the unfamiliar dog. This suggests that dogs are more motivated to help other dogs they know than to help unfamiliar dogs.

The scientist's argument would be most strengthened if it were true that, in the experiment, the dogs with access to the handle tended to release more food when

A. the behavior was being encouraged by a familiar person than when it was being encouraged by an unfamiliar person
B. the enclosure was empty than when it contained an unfamiliar dog
C. An unfamiliar dog in the enclosure was displaying hostility toward them than when an unfamiliar dog in the enclosure appeared friendly
D. a dog in the enclosure appeared uninterested in food already released into the enclosure than when it appeared interested in that food
E. a familiar dog was in the enclosure than when a familiar dog was visible but the enclosure was empty

2.The contingency-fee system, which allows lawyers and their clients to agree that the lawyer will be paid only in the event of success, does not increase the number of medical malpractice lawsuits brought against doctors. As attorneys must cover the costs for their time and research,they want to be assured that any medical malpractice case they accept on a contingency-fee basis has substantial merit. Consequently, attorneys turn away many people who come to see them, for lack of a good case.

The argument above is most vulnerable to criticism on the grounds that it fails to

A. specify the criteria attorneys use to judge the merits of a medical malpractice case
B. consider whether, in the absence of a contingency-fee option, even people with meritorious cases are much less likely to initiate litigation if they believe they might incur large legal fees
C. note whether, in successful medical malpractice lawsuits, the average monetary award after legal costs have been deducted is less under contingency-fee arrangements than otherwise
D. consider the effect of the contingency-fee system on the number of lawsuits sought for reasons other than medical malpractice
E. acknowledge the rising cost of medical malpractice insurance

3.27. The retinas of premature babies are not fully developed at birth. Because their retinas are so delicate, premature babies sometimes lose their sight. Methods for preventing this syndrome, which is called retinopathy of prematurity, have improved, but the proportion of premature babies who lose their sight because of this syndrome has increased.

Which of the following, if true, best reconciles the apparent discrepancy described above?

A. When premature babies are born, their retinas are developmentally unprepared to deal with light and air in the environment outside the womb.
B. The oxygen that must be administered to premature babies at birth can sometimes have a damaging effect on the babies’ retinas, but the oxygen is now administered in less damaging concentrations than it used to be.
C. The effects of retinopathy of prematurity can be reduced by controlling the exposure of premature babies to light and oxygen, but this method cannot completely prevent the syndrome.
D. The improvement of methods to prevent retinopathy of prematurity has been a gradual process, and there is still a need for further knowledge.
E. Improved medical technology is saving the lives of premature babies who would previously have died, but these babies have even more delicate retinas than do other premature babies and are more apt to lose their sight.

4.Under the agricultural policies of Country R, farmers can sell any grain not sold on the open market to a grain board at guaranteed prices. It seems inevitable that, in order to curb the resultant escalating overproduction, the grain board will in just a few years have to impose quotas on grain production, limiting farmers to a certain flat percentage of the grain acreage they cultivated previously.

Suppose an individual farmer in Country R wishes to minimize the impact on profits of the grain quota whose eventual imposition is being predicted. If the farmer could do any of the following and wants to select the most effective course of action, which should the farmer do now?

A. Select in advance currently less profitable grain fields and retire them if the quota takes effect.
B. Seek long-term contracts to sell grain at a fixed price.
C. Replace obsolete tractors with more efficient new ones.
D. Put marginal land under cultivation and grow grain on it.
E. Agree with other farmers on voluntary cutbacks in grain production.
