69.  The general availability of high-quality electronic scanners andcolor printers for computers has made the counterfeiting of checks mucheasier.  In order to deter suchcounterfeiting, several banks plan to issue to their corporate customers checksthat contain dots too small to be accurately duplicated by any electronicscanner currently available; when such checks are scanned and printed, the dotsseem to blend together in such a way that the word “VOID” appears on the check.
A questionableassumption of the plan is that
(A)  in the territory served by thebanks the proportion of counterfeit checks that are made using electronic scannershas remained approximately constant over the past few years
(B)  most counterfeiters who useelectronic scanners counterfeit checks only for relatively large amounts ofmoney
(C)  the smallest dots on theproposed checks cannot be distinguished visually except under strongmagnification
(D)  most corporations served by these banks will not have to pay morefor the new checks than for traditional checks
(E)  the size of the smallest dotsthat generally available electronic scanners are able to reproduce accuratelywill not decrease significantly in the near future


这一题问的不是 questionable assumption吗?E是一个正确的assumption啊,并没有questionable,我以为questionable assumption难道不是要削弱原题前提的吗??
求助。。泪奔

我觉得questionable assumption依旧是 assumption类型的题,因此依然可以用if not选出答案
其中questionable应该是“需要引起质疑的”这样的意思吧
也就是说想要知道银行的方法正不正确,需要质疑的(也就是要取得确认的)前提是

这就是questionable assumption。E选项读1次感觉不出来就读5次,10次,直到你读明白E选项的意思为止。
