标题: 求助：新prep 84

84. 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

答案是E，我选的是C，其实也不是特别理解，就是觉得其他选项挺无关，然后E算有点加强，不符合questionable。
关键就是纠结那个questionable，如果仅仅是assumption，E选项我就可以理解了。
因为作为前提，短期内电子扫描仪的精度不会提高，所以这些防伪小点就不会被不法人士复制出来，可以使方案成立。
那这个questionable是怎么回事呢？
我看到有解释说到这个是削弱的，说低估了科技发展云云，这种解释有点主观啊。
求牛人帮忙解惑答疑！
感激不尽！！！

It is indeed an assumption question, and E is one of the assumptions of the question.

Questionable assumption means it is an assumption, but is has no evidence to support.
We use this phrase usually in out argument essays.
