北美，2月11 号，放个逻辑狗

Evanma

11号考的，没换库，数学JJ全中，没有以外的题，轻松51.
作文考的航空公司因为油价贵而减少新航班那道， JJ很全了

Verbal烂到死， 离700太遥远，准备下个月再战。

这个月的逻辑JJ好少，放个逻辑狗。 现在脑子比较浆糊，等我明天回过神来想到更多再放别的。

说SEA OTTER最近有SIGNIFICANT DECLINE, 那为啥米呢？ 因为SEA LIONS和SEALS 减少了好多，那WHAEL 是专门捕食SEA LIONS 和SEALS 的， 所以怀疑WHAEL 饿急眼了，就开始捕食SEA OTTERS 了。 问加强。
我选了被SEA LIONS 和SEALS 捕食的动物都减少了，但是被SEA OTTER 捕食的动物没有减少。还有一个选项说在有WHAEL的水域和没有WHAEL 的水域里面SEA OTTER 都大量减少。。。
这个题的选项老郁闷了， 很绕，大家上场仔细斟酌

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.

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 the sea otter population at any North Pacific location declined in the 1980s because of substantial numbers of sea otters migrating to other locations.

C. Along the Pacific coast of North America in the 1980s,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.
