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.

看到问题问primary purpose，我就开始跳读，想掌握文章大意。 首先排除了B,C因为文章并不是举证或者是C当中的细节问题。 然后在读的过程中多次看到Bakker's这个名字，就看选项，感觉是在discuss，所以选择了A。 后来反思了一下，想知道A错误的原因是因为没有other scientists去论证讨论Bakker的观点么， 对于正确选项，有点迷茫，不知道evaluate怎么看出来的~想请教老师~ 文章主旨题，在跳读的时候需要注意什么问题呢，或者说问文章的意图这类题，有什么窍门么~

For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.
第二次做时，根据比较的逻辑不对称排除 A,B,C 在D,E的选择上。 先看到 economy的单复数，自己觉得没法判断，比较后面的内容，D用的是with，E用的是and， 用with 要去想 到底是伴随前面一句话啊，还是仅仅是D国的economy 用and 要去想 the unemplyoment 到底是指 D国的呢，还是后面的国家的呢。 用后面的差别都需要读者去思考，都显的不好，因而无法判断。 最后我只能按照economy与economies 之间的区别来做了。 请问老师 我的想法到底是哪出错了？

Because ethylene dibromide, a chemical used to fumigate grain, was blamed for the high rate of nerve damage suffered by people who work in grain-processing plants, many such plants switched to other chemical fumigants two years ago.  Since then, however, the percentage of workers at these plants who were newly diagnosed with nerve damage has not dropped significantly.  Therefore, either ethylene dibromide was wrongly blamed or else the new chemicals also cause nerve damage.

Lightbox, Inc., owns almost all of the movie theaters in Washington County and has announced plans to double the number of movie screens it has in the county within five years.  Yet attendance at Lightbox's theaters is only just large enough for profitability now and the county's population is not expected to increase over the next ten years.  Clearly, therefore, if there is indeed no increase in population, Lightbox's new screens are unlikely to prove profitable.
 
Which of the following, if true about Washington County, most seriously weakens the argument?
