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
