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.

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
 
Which of the following, if true, most strengthens the argument?

Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. If they expressed their honest views—about, say, their party’s policies—then achieving politically necessary compromises would be much more difficult. Clearly, the very insincerity that people decry shows that our government is functioning well.

Which of the following, if true, most seriously undermines this reasoning?
我想问一下这题c为什么不对呢？我觉得c是算他因削弱，影响民众judge politicians的不仅有sincerity还有别的。我想知道他因削弱和无关选项怎么区分呢？谢谢

For the period from the eighth century through the eleventh century, the shifting boundaries between Kingdom F and Kingdom G have not been well charted. Although a certain village in a border region between the two kingdoms usually belonged to Kingdom G, ninth-century artifacts found in the village were in the typical Kingdom F style of that time. It is unclear whether the village was actually a part of Kingdom F in the ninth century or whether it was a part of Kingdom G but had merely adopted Kingdom F's artistic styles under Kingdom F's cultural influence.

Which of the following would, if found in ninth-century sites in the village, best help in determining whether the village was a part of Kingdom F or Kingdom G in the ninth century?

这道题留下C，D和E中，错选了C。问题是要求找哪个可以作为证据来证明是K还是G。 请问一下C说的是刀和其他的工具从F里制造；D说的是G风格的陶瓷的原料只在F；请问一下C和D犯了什么逻辑错误。谢谢
