PREP1-84题，求助！

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

请问像这样的题应该怎样做？答案是E，可是C为什么不行。我的理解是：像这种题，有点类似EVALUATE的题型，要对选项进行support和weaken，而C选项的weaken是：最小的点在倍数大的放大镜下也看不出来。所以对结论没有weaken。因此选E。不知这样的理解对不？

这题是Assumption 不是evaluation

E是排除他因，如果一般的扫描仪in the near future能扫的点的size可以非常小，那么plan马上就没用了 ATAE啊

C说最小的点只能在放大镜下看，无所谓啊，能看出来就可以了
