In the late 1980s, 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?

[原创]12月13日,二战,广州,中雨,少量JJ。

Q50,V27,T640,二战。

首先感谢mccoist,要不是他贴出个帖子把所有的数学JJ都整理成WORD文档方便下载,我还满世界找JJ答案呢。

昨晚就开始下雨,直到现在。当按下按钮的时候,和预感的差不多,和模考也一致,鸡肋分数,申请学校估计没多大用处。有了一战的失利,这次反倒心情很平静。一战时Q和V都不好,这次Q上去了,但V和上次一样,一个月以来全职的复习结果竟让是V一点没有提高,分数和一战一样!超级郁闷,这个分数都不知道怎样面对家人,尤其是女朋友。有时怀疑自己到底应该不应该走留学这条路,都三十出头的人了。正在犹豫是否三战。

少量JJ,供XDJM参考:

AA:(并非原文,根据回忆如下)

Personnel director to executive office of Company X reported to management  team: since the company surveyed the employees when presented a list of issues of possible improvements in order of importance, employeed consistently ranked the communications between employees and management as the highest importance. Besides, the company held a series of information sessions between employees and management in which employees could attend on voluntary basis. The personnel director concluded that improvements in management have been made.

AI:(并非原文,根据回忆如下)

In the globalization and international cooperation, the role of people as the citizens of the world is more important than the role of a particular country.

Q:

偶记数学题不是很好,就不误导大家了。我的数学部分新题比较多,本月JJ大概10来道左右。快要考试的XDJM要好好利用我们CD里的数学JJ啊,尤其是数学和我一样不怎么样的。

RC:

1  讲细菌那篇;

2  法国的马赛,地中海贸易,进口税那篇;

3  cluster的优势和劣势;

4  时间不够了,放了。

CR:

有一道是说一个小镇的政府向当地的non-profit cultural organizations征收property tax;

还有一道是说海獭数量减少和鲸的关系。

SC:想不起来了。

数学新题实在是回忆不起来了,不过都不是很难,仔细些就好了。

我是那个男的,二战和你一战一样,惭愧。加你了已经,多交流有空。

谢谢各位的鼓励,不过很矛盾,岁数不小了。网站上建议国际学生前两轮申请,如果三战就要1月底,已经过了第二轮。这个分数又不甘心。谁能给些建议参考一下,多谢。

 请教楼主,CR第二个是不是这个阿,GWD-8-Q3CR:

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.
