So the correct answer is C, but I too believe it is too extreme. I picked (wrongly) E. I'm trying to understand why C is correct and still cannot follow. Anybody? I thought you shouldn't pick CR answers that are extreme, like these ones. To me, "even the most adept forgers" doesn't rule out the possibility that a forger gets luck w/ the pen pressure and speed. I'd be super thankful if someone can shed some light.

According to me, Option C is proper choice.

Reason :- though we can not rule out possibility that many user will be denied legitimate access,this will be bit weaken side of the argument.

While in this argument author is more concern about being positive as he says " even most forgers can not duplicate all characteristics"

In the sentence, most is meant to describe adept, not forgers. Option C states that even the best forger cannot get past such security which I think is totally in line with the passage. Moreover, option E I think goes a little too far mentioning "many" authentic users. A correct option E should have looked like " ... some/few authentic users..."

"identifies a person’s signature by analyzing not only the form of the signature but also such characteristics as pen pressure and signing speed." is the key line to answer this question.

We are told that this technique makes use of others things as well while analyzing the signature.

So, if one forges the signature and doesn't know the speed/pressure, it would almost be impossible for that person to dig into the system.

So, C clearly states this idea that only forging signature is not going to help.

E is wrong because it is actually weakening the premise by stating that the technique used by software is not helpful as it has not taken into account the point mentioned in E.

Remember on GMAT, a premise is always a source of truth that cannot be denied.

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.


Type- Inference
Boil it down - Even the most adept forgers cannot duplicate all of the characteristics the program analyzes.

(C) Nobody can gain access to a computer equipped with the software solely by virtue of skill at forging signatures. - Correct - This is a restatement of the premise
