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.
 
The argument above requires which of following assumptions?

选项:

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.

Most of the purported health benefits of tea comes from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C that inhibit the formation of plaque along the body's blood vessels.
第一遍做选了C 先排除AB 根据A vitamin C that。。。歧义就开始看每个选项句子的末尾，然后就把D排除了 又根据found 和 inhibit的发起者都是 compound ，they重复，把 E 排除了。 看到C 还觉得 found 和 inhibit 一致，乐乐地选了C。 review：看到答案的时候也明白D选项意思正确，用两个that引导的并列从句描述compound。 还自己说服自己C选项如果非要找个与and inhibit 对称的话，那只有和come去对称了，那就引起歧义了。完全没有注意found的具体意思和性质。 可以听的录音里面也是比较CD，老师一上来就说found是个分词。 我读的时候就觉得found是个动词么。 请问过去分词和动词的过去式是怎么区分的？ 还有我排除D的这个思路。。我做题时总是没有抓住每个选项的真正不同之处去排除。。老看到细枝末节。。。这可怎么办呢？

For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont.  Police studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont.  Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.
