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.

B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light.  These people do, however, show normal sensitivity to most components of dim light.  Their retinal cells are also not excessively sensitive to red components of moderately bright light.
 
The information above best supports which of the following hypotheses about people with the disorder described, if they have no other serious visual problems?

Which of the following most logically completes the passage?

Psychologist: In a study, researchers gave 100 volunteers a psychological questionnaire designed to measure their self-esteem. The researchers then asked each volunteer to rate the strength of his or her own social skills. The volunteers with the highest levels of self-esteem consistently rated themselves as having much better social skills than did the volunteers with moderate levels. This suggests that attaining an exceptionally high level of self-esteem greatly improves one's social skills.

The psychologist's argument is most vulnerable to criticism on which of the following grounds?

题目主要是根据这些高自尊心的志愿者认为自己有更好的社交能力从而推断出高的自尊心可以提高人的社交能力。 我直接想的是是否存在其他原因影响人的社交能力选了E，可是错了。后来看了答案是C，发现有个gap这些志愿者自己认为自己社交能力高不等同于他们社交能力高。懂了后并不知道为什么E选项是错的。请老师指教

Jay: Of course there are many good reasons to support the expansion of preventive medical care, but arguments claiming that it will lead to greater societal economic gains are misguided. Some of the greatest societal expenses arise from frequent urgent-care needs for people who have attained a long life due to preventive care.

Sunil: Your argument fails because you neglect economic gains outside the health care system: society suffers an economic loss when any of its productive members suffer preventable illnesses.

Sunil's response to Jay makes which of the following assumptions?

可以请老师帮忙理下这题逻辑链么，读了好多遍还是没懂其中的逻辑关系。这道题做的好晕，Jay认为最大的社会费用来自于老年人的紧急护理需求，这句话怎么就反驳了预防性医疗服务的增加导致更多的社会经济收益这个观点的。 然后Sunil如何反驳的也没怎么懂
