1、A major chemical spill occurred five years ago at Baker's Beach, the world's sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching. Yet the number of adult female Merricks returning to lay their eggs at Baker's Beach has actually increased somewhat since five years ago. Clearly, environmentalists' prediction that the world's Merrick population would decline as a result of the spill has proven unfounded.

Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists' prediction?

A The chemical spill five years ago occurred at a time when there were neither Merrick sea turtles nor Merrick sea turtle eggs on Baker's Beach.
B Female Merrick sea turtles begin returning to Baker's Beach to lay their eggs when they are ten years old.
C Under normal conditions, only a small proportion of hatchling female Merrick sea turtles survive in the ocean until adulthood and return to lay their eggs at Baker's Beach.
D Environmental pressures unrelated to the chemical spill have caused a significant decline in the population of one of the several species of sea birds that prey on Merrick sea turtle eggs.
E After the chemical spill, an environmental group rejected a proposal to increase the Merrick sea turtle population by transferring eggs from Baker's Beach to nearby beaches that had not been affected by the spill.

2、Though sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect. Recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth.

In order to evaluate the argument, it would be most helpful to determine which of the following?

A Whether zinc is effective only against colds, or also has an effect on other virally caused diseases
B Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds
C Whether people who frequently catch colds have a zinc deficiency
D Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc
E Whether the zinc gel has an effect on the severity of cold symptoms, as well as on their duration

3、Some people have questioned the judge's objectivity in cases of sex discrimination against women. But the record shows that in sixty percent of such cases, the judge has decided in favor of the women. This record demonstrates that the judge has not discriminated against women in cases of sex discrimination against women.

The argument above is flawed in that it ignores the possibility that

A a large number of the judge's cases arose out of allegations of sex discrimination against women
B many judges find it difficult to be objective in cases of sex discrimination against women
C the judge is biased against women defendants or plaintiffs in cases that do not involve sex discrimination
D the majority of the cases of sex discrimination against women that have reached the judge's court have been appealed from a lower court
E the evidence shows that the women should have won in more than sixty percent of the judge's cases involving sex discrimination against women

4、People who have spent a lot of time in contact with animals often develop animal-induced allergies, a significant percentage of which are quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. However, a zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.

Which of the following hypotheses receives the strongest support from the information given?

A The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population.
B Zoo employees tend to develop animal-induced allergies that are more serious than those of other people who spend equally large amounts of time with animals.
C Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than is exposure to the kinds of animals that are kept in zoos.
D There is no occupation for which the risk of developing an animal-induced allergy is higher than 30 percent.
E Among members of the general population who have spent as much time with animals as zoo employees typically have, the percentage with animal-induced allergies is significantly more than 30 percent.

5、Journalist: In late 1994, the present government of the Republic of Bellam came into power. Each year since then, about thirty journalists have been imprisoned for printing articles that criticize the government. In 1994, under the old government, only six journalists were imprisoned for criticizing the government. So the old government was more tolerant of criticism by the press than the new one is. Politician: But in 1994 only six journalists criticized the government, and now journalists routinely do.

The politician challenges the journalist’s argument by doing which of the following?

A Presenting data that extend further into the past than the journalist’s data
B Introducing evidence that undermines an assumption of the journalist’s argument
C Questioning the accuracy of the evidence presented in support of the journalist’s conclusion
D Pointing out that the argument illegitimately draws a general conclusion on the basis of a sample of only a few cases
E Stating that the argument treats information about some members of a group as if it applied to all members of that group
