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.

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

Editorial:
 
In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker's income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.
 
Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?

Editorial:
 
An arrest made by a Midville police officer is provisional until the officer has taken the suspect to the police station and the watch commander has officially approved the arrest.  Such approval is denied if the commander judges that the evidence on which the provisional arrest is based is insufficient.  A government efficiency expert has found that almost all provisional arrests meet standards for adequacy of evidence that watch commanders enforce.  The expert therefore recommends that the watch commander's approval should no longer be required since the officers' time spent obtaining approval is largely wasted.  This recommendation should be rejected as dangerous, however, since there is no assurance that the watch commanders' standards will continue to be observed once approval is no longer required.
 
In the editorial, the two portions in boldface play which of the following roles?

Industrial accidents are more common when some of the people in safety-sensitive jobs have drinking problems than when none do.  Since, even after treatment, people who have had drinking problems are somewhat more likely than other people to have drinking problems in the future, any employer trying to reduce the risk of accidents should bar anyone who has ever been treated for a drinking problem from holding a safety-sensitive job.

Sunflowers growing in pots were placed, with their roots submerged, in the pond contaminated with radioactive elements.  The sunflowers kept growing; in the process, they absorbed radioactive elements.  Within twelve days, 85 percent of the radioactive elements were removed from the water, which is no less than can be accomplished with the much more expensive conventional filtration techniques.  Scientists therefore propose using sunflowers for decontamination wherever there are radioactively contaminated ponds.
 
Which of the following, if true, points to a limitation on the applicability of the proposed method of decontamination?
留下B、D选项。排除B的是因为原文第一句已经叙述sunflower怎么在ponds中起作用的过程，由此得出这个过程一定成立，那么B说ponds太冷会导致这个过程不能继续是在抬杠。 REVIEW的时候发现可能是D被我发散了，究竟哪个品种对消除辐射有效和问题说的实施的限制无关。B是不是算长得像正确选项？因为它讨论的是能不能。
