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

Thegeneral availability of high-quality electronic scanners and color printers forcomputers 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 dotstoo small to be accurately duplicated by any electronic scanner currentlyavailable; when such checks are scanned and printed, the dots seem to blendtogether in such a way that the word “VOID” appears on the check.
Aquestionable assumption of the plan is that
A.in the territory served by the banks the proportion of counterfeit checks thatare made using electronic scanners has remained approximately constant over thepast few years
B.most counterfeiters who use electronic scanners counterfeit checks only forrelatively large amounts of money
C.the smallest dots on the proposed checks cannot be distinguished visuallyexcept under strong magnification
D.most corporations served by these banks will not have to pay more for the newchecks than for traditional checks
E.the size of the smallest dots that generally available electronic scanners areable to reproduce accurately will not decrease significantly in the near future

答案为E,我当时选的是C,主要是看不懂问题:问的是questionable assumption,当时感觉,既然是questionable,应该找驳斥的assumption吧。。。。但是答案给的是这个方案成立的假设。。。。感觉自己读题严重跑偏。。。。肿么办!!!求助NN!!!以前高三的时候经常犯这种非主流的错误,大家都不错的我就错,大家都错的我还错。。。。请允许我做一个悲伤的表情。。。。~~~~(>_<)~~~~ T T

questionable assumption就是有“疑问的假设”,也就是一个faulty assumption,错误的假设。
这个假设没有对argument起到加强作用,反倒起到了削弱作用。

这个题的逻辑链是银行在支票上印出很小的点儿,因为目前现有的盗版打印机的分辨率无法打印出那么小的点儿,如果把点儿复印成目前盗版打印机的可以打印的最小分辨率,一个VOID的字就会在支票上显现出来(原版的因为点儿太小,看不出来)。
这个“疑问的假设”就是银行假设目前盗版打印机的可以打印的最小分辨率不会在短时期内有巨大的进步。因为如果目前盗版打印机的可以打印的最小分辨率跟银行印出来的支票一样了,那么银行这个防伪手段就失败了。

这个题目其实就是问假设的。
questionable assumption的意思是:错误的假设是什么。

但是E明明就是一个原题的一个合理正确的假设啊。。。没觉得E有错误啊。。。为什么还要questionable

你好,你的解释我明白了,就是不明白为什么这个是“疑问/错误的假设”呢? 这不就应该是“银行方面的假设”吗?
银行假设盗版打印机无法伪造这些小点,所以银行弄出这些小点来防伪。 为什么是错误的假设?

题目问的是这个questionable assumption 指的是 正确选项中的assumption是questionable的(有争议性的)。e选项指的是:电子打印机几年之后能够打印的小点点也不会再小了(科技从未进步)。
因此support了原文的点,这个特殊的辨别真伪的方法是可行的。但是这个assumption是有争议性的。可以当假设做。
