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.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect. However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack. Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.

Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
排除了A和D选项，但剩下选项和原文的关系完全不懂（我读的懂argument，但看不懂选项，也理不清选项和原文之间的关系）。想请教这种支持一个（假设），驳斥另一个（假设）的做题方法。

请问郭老师，文章脉络听懂了，但是看到frequency就直接去文中找关于frequency的字样，然后定位了第一段最后一句。 说的就是present-day 的 species 里面breakage 频率低啊，选了d。每次遇到这种题，我都是先去文中找类似字样，不知道这样对不对？

想问一下金老师，句子最后加逗号后面有ed形式的非谓语动词，它的主语是不是可以是主句的主语，也可以是整个主句，还可以是离它最近的一套完整主谓宾的主语？还有如果是逗号加ed形式的非谓语动词在句子中间的话，是直接当做修饰前面的句子的主语还是离得最近的一个名词，还是后面句子的主语呢？

老师，能解释一下这道题吗，这句的主语是tobacco company,ACD 选项后面的从句都是thereby slowing，可是company不能slow the rate啊我这样理解怎么错了
