题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

老师，我听了之前的录音知道应该定位到第三段，the alternative to.......这一句，但是我当时做题是没太懂的是 the alternative to 是什么意思？这后面说的内容难道不是和constructivists相反的观点吗？ 请老师分析一下我的思路错误以及如何提高我这方面的能力，谢谢。

Many entomologists say that campaigns to eradicate the fire ant in the United States have failed because the chemicals that were used were effective only in wiping out the ant's natural enemies, which made it easier for them to spread.
老师你好，这道题不能用which是不是因为指代不明确呢？which就近指代到natural enemies不符合句子逻辑，也可能往前指代到chemicals、campaigns，所以要排除AB。然后CD的it指代什么呢？C选项them是不是指代对象不明，没有D好呢？E选项为什么错呢？我读的特别不通顺，直接排除了，但是说不出哪里不对。想请王文静老师解答一下，谢谢！

A mutual fund having billions of dollars in assets will typically invest that money in hundreds of companies, rarely holding more than one percent of the shares of any particular corporation.
我想请问下Tina老师，这道题A选项能不能当成因果关系理解呢？我是这么读出来的：有很多钱的这个资金投在了数以百计的公司上（虽然他们钱多，但是投的公司多啊，应该是想表述资金投的比较分散没有往一个地儿投），所以很少占超过任一特定公司1%的股份。所以用分词表示伴随的一个结果很合适。 然后，虽然D用so that表示因果关系，但是这个they只能指代前面的公司了，句意上不合适，所以选A。这样的思考过程，不知道有没有问题，谢谢老师
