标题: 问题和OG13 第六题一样，但是选项不一样，大家可以看一看

Parland’s alligator population has been declining in recent years, primarily because of
hunting. Alligators prey heavily on a species of freshwater fish that is highly valued as
food by Parlanders, who had hoped that the decline in the alligator population would lead
to an increase in the numbers of these fish available for human consumption. Yet the
population of this fish species has also declined, even though the annual number caught
for human consumption has not increased.

Which of the following, if true, most helps to explain the decline in the population of the
fish species?

A. The decline in the alligator population has meant that fishers can work in some
parts of lakes and rivers that were formerly too dangerous.

B. Over the last few years, Parland’s commercial fishing enterprises have increased
the number of fishing boats they use.

C. Many Parlanders who hunt alligators do so because of the high market price of
alligator skins, not because of the threat alligators pose to the fish population.

D. During Parland’s dry season, holes dug by alligators remain filled with water long
enough to provide a safe place for the eggs of this fish species to hatch.

E. In several neighboring countries through which Parland’s rivers also flow,
alligators are at risk of extinction as a result of extensive hunting.

这题只需要看题干的最后一句话就可以做：
Yet the population of this fish species has also declined, even though the annual number caught
for human consumption has not increased.
这就是等于明着告诉你“去找不是因为被人吃了而减少的原因”
AB-因为human consumption has not increased，排除
CE-只讲鳄鱼，没讲fish
D讲的是鳄鱼少和fish少之间的关系，就选他。

这题是GMAC典型的出题套路：
围绕着A讲一堆balabala，结论说B怎么了。答案必须是说A与B的关系（AB都有），这是答案的内容，形式可以是A与B的比较，A与B的相同或者不同点。
而错误答案往往是只围着A说或者B说。

我总结了一下，以前我讲题都是按照Helr的分类去讲，这个方法有其局限性，最主要的特点就是在过程中消耗大量脑力，考试的时候如果晕菜用不出来。对逻辑的要求也高些。
以后，我会按照怎么容易做，怎么讲，不一定拘泥于某个特定的方法。
