我推测39的答案大概就是说吃o和b的海洋动物在没o和b的时候就会去吃a了

25题大概能推出来 1995年re中被resis的比例要远远大于1994

20.M地发现了一部战车，是希腊军队用的。而希腊军队曾经攻陷过M。现在M地区生长的木头和战车所使用材料一样树种。而现代的树种中含有高浓度的K物质，而K物质没有在战车中发现，所以结论是时间越长K物质在此树种中聚集越多。问assumption是什么。选了一个好像是希腊军队攻陷M以后用了本地生长的这种树制成了这个战车。
            

应该是在希腊军攻陷M后才有这种树吧?
            

树在地下,K不会随时间变少. 这个对吗?   我看这两个才取非削弱 (由题目推, 非jj)

支持，希望到23号考试的时候能有大部分的题目崭露头角～！

39题貌似和一道GWD题很像，只不过GWD问的是weaken,贴出来大家看哈，记不起来是哪套题的了：（

  In the late 1980s, the population of sea otters in the North Pacific began to decline. There are two plausible explanations for the decline: predation, possibly by killer whales, or disease. Of these two, disease is the more likely, since a concurrent sharp decline in populations of seals and sea lions is believed to have been caused by disease, and diseases that infect these creatures are likely to be able to infect sea otters also.

A.      Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.

B.      There is no indication that the sea otter population at any North Pacific location declined in the 1980s because of substantial numbers of sea otters migrating to other locations.

GWD-8-Q3:

In the late 1980’s, the population of sea otters in the North Pacific Ocean began to decline. Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely. After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably.

Which of the following, if true, most seriously weakens the reasoning?

A.      Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.

B.       There is no indication that substantial numbers of sea otters migrated to other locations from the North Pacific in the 1980’s.

C.      Along the Pacific coast of North America in the 1980’s, sea otters were absent from many locations where they had been relatively common in former times.

D.      Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters’ main food source.

E.       The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.
