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.

In the past several years, astronomers have detected more than 80 massive planets, most of them as large or larger than Jupiter, which circle other stars.
根据at least as large as 相对比as large or larger than好，留下了CD，which circle的话让我感觉是句子的逻辑主语变化了，而circling的话说明逻辑主语没变化，但是这句句子的主语不是astronomers吗，如果是circling的话不就是天文学家绕。。。明显语义错误了。求教老师。

Although producer prices rose at an unexpectedly steep rate in September, analysts said that the increase resulted mostly from temporary factors and not necessarily foreshadowing that there would be a resurgence of inflation.
这道题根据前后的语义留下了AC，analysts认为这个增加来自于 temporary factors 和错误地预测了。。。因为这两个因素应该是平行的，所以选了foreshadowing ，请老师纠正。

When a polygraph test is judged inconclusive, this is no reflection on the examinee.  Rather, such a judgment means that the test has failed to show whether the examinee was truthful or untruthful.  Nevertheless, employers will sometimes refuse to hire a job applicant because of an inconclusive polygraph test result.
 
Which of the following conclusions can most properly be drawn from the information above?
老师，这道归纳题我做的第一遍读时候根据肯定不沾边的只留下了DE。结果答案是C。我想请麻烦问老师读一下这些选项，看我是不是句子的意思理解错了。

Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.  However, a study has found that almost all scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs.  Since creative breakthroughs by scientists under forty also generally occur within a dozen years of the scientist's entry into the field, the study's finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.

CDE排除，留下了AB，因为原文说的是contractor and engineer两个人，A是both,B是each。OG上SC的review上有一句说：both代两个人，each代3个人以上。所以立即选了A。 是不是断章取义了。 The contractor and the engineer agree on the cause of the bridge failure, but both blame the other.
