Firstly, my reasoning behind reaching to an answer.

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. - Background

Even the most adept forgers cannot duplicate all of the characteristics the program analyzes. - Premise

Restating the argument - Comp Soft. restricts forgery by not only form of signature but also other characteristics such as pen pressure and writing speed. Its difficult for forgers to duplicate all of the characteristics of forgery a program analyzes.

Going to options:

(A) The time it takes to record and analyze a signature makes the software impractical for everyday use.
Nothing about the efficiency in terms of speed is mentioned. Thus, eliminate.

(B) Computers equipped with the software will soon be installed in most banks.
While Banks are the ones that might use this software more often but nothing is mentioned in the argument. So, Eliminate.

(C) Nobody can gain access to a computer equipped with the software solely by virtue of skill at forging
signatures.
The premises mentions that forgery cannot be done just on the basis of signature form. The software also analyses other forms such as pen pressure and writing speed. Other characteristics are almost impossible to forge even for an adept forger. So, correct.

(D) Signature-recognition software has taken many years to develop and perfect.
Nothing about development efforts is mentioned. So, eliminate.

(E) In many cases even authorized users are denied legitimate access to computers equipped with the
software
The argument does not mention anything about the misses of access a legitimate user will have. There could be a possibility that because of intense security the software tries to provide, it may deny access to legitimate users. However, nothing in the argument is given. Thus, eliminate.

My question is : If option C was "Nobody can gain access to a computer equipped with the software by forging signatures" WOuld it be too strongly worded("Nobody") to eliminate? What would we choose then option E?

Firstly, I am wondering why are you trying to change the option? Even if you do, then I think this option will become too extreme but still remains best when compared to E for the reason mentioned behind eliminating E.

If something about the user experience related to difficulty of access for legitimate users were given in argument then E would have fared over C. However, with argument as it is and with modified C, option C, in my opinion, still stands best in comparison to other choices.

in case of C, it is not specified as Signature login is the only way to access the computers. Users may still access using passwords. Nobody is generalization & not allowed in CR.


Answer could be E as legitimate users can sometimes make signature with different pressure or speed.

my answer is E.
