A computer equipped with signature-recognition software, which restricts access to a computer to those people whose signatures are on file, identifies a person's signature by analyzing not only the form of the signature but also such characteristics as pen pressure and 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?
The time it takes to record and analyze a signature makes the software impractical for everyday use.
Computers equipped with the software will soon be installed In most banks.
Nobody can gain access to a computer equipped with the software solely by virtue of skill at forging signatures.
Signature-recognition software has taken many years to develop and perfect.
In many cases even authorized users are denied legitimate access to computers equipped with the software.
C选项=最后一句Even the most adept forgers cannot duplicate all of the characteristics the program analyzes.
E选项很有迷惑性，但E选项只是有可能而已，C选项是原文paraphrase了一下，百分百正确。
没注意 forger
先排除B/D，从题目信息中无法推断出；A选项record signature不会影响到software的使用，而应该是identify signature的复杂性影响software的使用；E选项在某种意义上是正确的，因为software不仅要求signature form要一样，且要求open pressure和signing speed也要一样，很有可能某些时候authorized users也会被denied。但相比较C选项而言，C选项更准确，因为C选项不存在不确定性。而GMAT要求的是最适合的选项，而不是正确的选项，所以正确选项是C。
在E上纠结了一会，个人感觉E如果加个forger之类的词会更好
