Even though OA is C. I am kind of in an opinion that C is a bit extreme. The last sentence says MOST forgers can not replicate the signature. -> There are some exceptions right!. So, Some people can access through their forgery skills itself.
@abhimanha , GMATNinja Can you please tell me whether my reasoning is right or am missing something.

from GMAT itself we have learnt about that 'Nobody' is too extreme. So here, Gmat is making trap by digging chasm in its own rule. Though not a single answer is perfectly right but for every answers we have the reason to eliminate. Really I am bit in a quandary.

Nightmare007 and soumya170293, I believe your questions were specifically addressed in this post.

"Even the most adept forgers..." is not the same as "Most adept forgers..." Also, there is no reason why we cannot have "extreme" language in a correct answer choice.

so you are saying that the most is an extension attached to adept not forgers?

Yes, exactly!

Consider the group of all adept forgers... out of that group, the top X% could be considered the most-adept forgers.

For example, many talented athletes play soccer. But only the most talented players (small subset of that group) play in professional soccer leagues.

Practice Question
Question No.: 19
Page: 122
Difficulty:

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?

(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.

Hi jennpt - I selected (C) but I was not confident about usage of "nobody" in (C) - pls guide me!!

Hi CAMANISHPARMAR

It's good to be suspicious of extreme language like "nobody". However, we have some extreme evidence that will allow us to choose it:
The paragraph says "even the most adept forgers" cannot master all of the things the software is analyzing and thus fool the software. Luckily this is a really broad statement that includes all the best forgers in the world, period.

(The text did not give us a group that might be incomplete. For example, "the winners of a forging contest" or "the top graduates from Signature Forgery University" ... Those would be groups that might be missing a hidden talent, and there could be some kid sitting in Dubai or a lady in San Francisco who are just ridiculously good but no one knows about their talent. But the text gave us a broad statement that includes the best forgers in the world - and this would include people who aren't even famous.)

So if even the best forgers in the world can't fool the software with their forging, then no one can fool it - at least by forging.

C leaves the door open that there might be other ways to fool the software, which is another mark of a good answer: it limits itself to what we know about here, which is forging.

Hope this helps. Let me know.

Best, Jenn
