OG-142

142. A computer equipped with signature-recognition software, which restricts access to acomputer to those people whose signatures are on file, identifies a person’s signature byanalyzing not only the form of the signature but also such characteristics as pen pressureand signing speed. 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.

(E) In many cases even authorized users are denied legitimate access to computers

equipped with the software.

Answer: C. What I don't understand is the explaination to Choice E: "The passages give no reason to think that errors of the sort that choice E describes,even if made, would be numerous." So if I change Choice E to "Even authorized users may be denied legitimate access to computersequipped with the software", can it be a conclusion from the argument?

Why "many" in E is so important? Thanks a ton.

和这题类似的有一个是 说什么冬冬是用指纹来打开的，具体题目我记不清了，但是和这题很类似。

这题C的正确性十分明显，这是其一

至于E的错误，就是在于这个MANY,

无论从原文的哪一个地方都无法得出MANY 这个结论，只能说是有这种现象发生，原文中没有任何一处说明了这种现象的发生是很频繁的啊。所以这个many无从谈起。

如果我把这个many改成sevral也是不对的，因为原文没有对事件发生的频率作出说明。

指纹那题以后你再看到了就会弄清这题的。

in this argument, the speaker said that the software was so strict that no forgers could imitate imformation . you should pay attention that the vital thing in the argument is the software and the speaker said nothing about the conclusion you mentioned .

i think you can go back to see the direction of the OG. it said that we will be wrong if we draw

a conclusion with information not in the argument.

my english is not so fluent. i hope it wii help!^ _ ^

我觉得C也不对啊，C中的nobody也用得太强了吧？

文中只是说Even the most adept forgers cannot duplicate all of the characteristics the program analyzes.但没有说一个人都不可能模仿他人的签名而获得成功。

大家看呢？

严重同意，而且我觉得conclusion题和assumption题一样是在找必要条件，先把原文当真理，然后从选项中找一定要成立的，比如E就不一定成立，因为完全有可能是所有authorized users都可以打开电脑

我还有个问题，请问OG中对E的解释，the passages give noreaxon to think that errors of the sort that choice E describes ,even ifmade  ,would be numerous.这句话看不懂，请nn们解释一下，谢谢

意思就是：文章并没有提到E所描述的这种情况，即使是发生这样的情况，那也不是“MANY”，而是numerous。

其实很多人乍一看会选E，觉得事实上会发生这种情况。但注意：文中没有往这个方向上推，自始自终都说不可能仿造而已。E，的情况是你自己联系常识想出来的，从文中并不能conclude出。所以，E是一个陷阱。
