84.        (26216-!-item-!-188;#058&001794)

The general availability of high-quality electronic scanners and color printers for computers has made the counterfeiting of checks much easier.  In order to deter such counterfeiting, several banks plan to issue to their corporate customers checks that contain dots too small to be accurately duplicated by any electronic scanner currently available; when such checks are scanned and printed, the dots seem to blend together in such a way that the word “VOID” appears on the check.

A questionable assumption of the plan is that

A. in the territory served by the banks the proportion of counterfeit checks that are made using electronic scanners has remained approximately constant over the past few years

B. most counterfeiters who use electronic scanners counterfeit checks only for relatively large amounts of money

C. the smallest dots on the proposed checks cannot be distinguished visually except under strong magnification

D. most corporations served by these banks will not have to pay more for the new checks than for traditional checks

E. the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future

答案选E。 选项说电子扫描仪未来能是别的最小的点不会变小，那不就是说明这个plan是可行的吗？为什么是questionable assumption呢?

我也有点蒙，但是其他四个确实irrelevant

仔细想想，觉得好像题目的考点是要我们add an assumption to make the conclusion reasonable. E是一个需要我们add的assumption, 而实际的support过程没有这点。所以是一个questionable assumption,是不是这个意思？不是很确定

这个题不好理解的关键是questionable assumption

前几个根据都是事实，只E不能作为根据，你不能说我认为近几年不会……，所以我们可以实行这个计划。

谢谢~!!不过感觉就算是add一个assumption进去也不是一个questionable assumption哦~不过看了下面的回复好像终于有一点点说的通的感觉..上面四个好像连assumption都算不上...哭...先这么理解吧~
