4. A survey was recently conducted among ferry passengers on the North Sea. Among the results was this: more of those who had taken anti-seasickness medication before their trip reported symptoms of seasickness than those who had not taken such medication. It is clear, then that despite claims by drug companies that clinical tests show the contrary people would be better off not taking anti-seasickness medications.

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

(A) Given rough enough weather, most ferry passengers will have some symptoms of seasickness.

(B) The clinical tests reported by the drug companies were conducted by the drug companies' staffs.

(C) People who do not take anti-seasickness medication are just as likely to respond to a survey on seasickness as people who do.

(D) The seasickness symptoms of the people who took anti-seasickness medication would

have been more severe had they not taken the medication.

(E) People who have spent money on anti-seasickness medication are less likely to admit symptoms of seasickness than those who have not.

WHY D?

14. The average level of fat in the blood of people suffering from acute cases of disease W is lower than the average level for the population as a whole. Nevertheless, most doctors believe that reducing blood-fat levels is an effective way of preventing acute W.

Which one of the following, if true, does most to justify this apparently paradoxical belief?

(A) The blood level of fat for patients who have been cured of W is on average the same as that for the population at large.

(B) Several of the symptoms characteristic of acute W have been produced in laboratory animals fed large doses of a synthetic fat substitute, though acute W itself has not been produced in this way.

(C) The progression from latent to acute W can occur only when the agent that causes acute W absorbs large quantities of fat from the patient's blood.

(D) The levels of fat in the blood of patients who have disease W respond abnormally slowly to changes in dietary intake of fat.

(E) High levels of fat in the blood are indicative of several diseases that are just as serious as W.

WHY C?

Questions 17--18

The question whether intelligent life exists elsewhere in the universe is certainly imprecise, because we are not sure how different from use something might be and still count as "intelligent life" Yet we cannot just decide to define "intelligent life" in some more precise way since it is likely that we will find and recognize intelligent life elsewhere in the universe only if we leave our definitions open to new, unimagined possibilities.

18. The passage, if seen as an objection to an antecedent claim. Challenges that claim by:

(A) showing the claim to be irrelevant to the issue at hand

(B) citing examples that fail to fit proposed definition of "intelligent life"

(D) arguing that the claim, if acted on, would be counterproductive

(E) maintaining that the claim is not supported by the available evidence.

WHY D?

22. In an experiment, two-year-old boys and their fathers made pie dough together using rolling pins and other utensils. Each father-son pair used a rolling pin that was distinctively different from those used by the other, "father-son pairs, and each father repeated the phrase "rolling pin" each time his son used it. But when the children were asked to identify all of the rolling pins among a group of kitchen utensils that included several rolling pins, each child picked only the one that he had used.

Which one of the following inferences is most supported by the information above?

(A) the children did not grasp the function of rolling pin.

(B) No two children understood the name "rolling pin" to apply to the same object

(D) Each child was able to identify correctly only the utensils that he had used.

(E) The children were not able to distinguish the rolling pins they used from other rolling pins.

WHY B?

4. D的意思是the seasickness symptoms of the people who took anti-seasickness medication would have been more severe if they had not taken the medication.这样一来，也就是说虽然药没完全治好seasickness,但减轻了一些，也就是说吃药对他们还是有好处的。
