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.

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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

As the honeybee's stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing the bee to sustain a fatal injury.
老师我是这么做这道题的：首先判断出句子的重点在蜜蜂的刺怎么着导致了...所以AB没有突出这个蜜蜂的刺，先排掉（同时B这个句子也没谓语），然后CDE里面我觉得不是“蜜蜂的刺”这个刺本身导致了什么东西，而是说这个刺的一些行为，特点,也就是heavily barbed and stays where it is inserted导致了什么东西。所以我排掉了C和D。我觉得答案应该选E，而且我查了下prep的答案也是E。不知道我的思路是不是有问题，还请老师指点，谢谢老师!

Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species:  a hare, a partridge, and various Mediterranean fish.  Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.  Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

Of patients over 65 years old who survived coronary bypass surgery—a procedure widely prescribed for people with heart disease—only 75 percent benefited from the surgery.  Thus it appears that for one in four such patients, the doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.
 
Which of the following, if true, most seriously undermines the argument?
⼼
我选了D 读原文后 原文是在说65岁以上有75%的人得益处 医生让他们接受手术是因为想得到练习还有费用的好处 不是想帮助他们 我会觉得原文在问 竟然只有那么些人可得益处 为什么医生还要叫他们做手术？ B回答说 因为手术还有其它好处 D回答说 65岁的人没得好处的在手术前已被告知风险 E回答说 接受手术不得好处的人在手术前接受的药物与得益处的人是一样的 我对于说的是同一件事还是不是很了解 就得他们都有回应原文 特别是B 但想不通E怎么说的是一回事 手术前接受的药物一不一样 跟医生要病人做手术的原因 是一回事吗
