Even the most adept forgers cannot duplicate all of the characteristics the program analyzes.
Which of the following can be logically concluded from the passage above?
(A) The time it takes to record and analyze a signature makes the software impractical for everyday use.
(B) Computers equipped with the software will soon be installed in most banks.
(C) Nobody can gain access to a computer equipped with the software solely by virtue of skill at forging signatures.
(D) Signature-recognition software has taken many years to develop and perfect.（C）
(E) In many cases even authorized users are denied legitimate access to computers equipped with the software.
我选了E。 选C是因为标蓝的句子吗？

我怎么有印象以前做过类似说法的题答案选了E？ 现在我明白E不是用题里的条件肯定能推出来的，只是一种可能发生事件，但是C肯定是能推出来的，因为 Even the most adept forgers cannot duplicate all of the characteristics the program analyzes. 所以没有人能只用forge signature来gain access.作者: 小伊YSY 时间: 2011-8-29 00:56
