### HideShow timer Statistics

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
the software.
If you have any questions

Great Question - It came down to C and E - I'm going with C

A) Discusses practicality - not mentioned in the passage
B) Discusses use of software - not mentioned in the passage
D) Discusses period of development - not mentioned

E) The passage implies that it is difficult to forge the signature, I don't think we can conclude it would be difficult for authorized user to use it.

C) We can assume this by this line "the most adept forgers cannot duplicate all of the characteristics."
Note with the protection it doesn't mean there is no way to gain access as an unauthorized person (hacking, remote connection etc.)

E sounds most plausible. C says that even the most skilled forgers cannot gain access just by forging signatures. This implies that along with forging the form of the signatures, if the forgerer has other skills, he may be able to gain access. This is not what the stimulus says, though. The stimulus clearly states that even the most skillful forger cannot gain access to the computer.
This leaves us with E. Who is the most skillful at forging your signature? You, yourself. So there might be times when you, the authorized person, may not be able to replicate your own signing speed and pen-pressure, and may therefore, be denied access.

I go with C too because the premise states that even the foragers with a lot of skills have trouble getting it right under this new technological innovation, thus it automatically leads to the conclusion in C.
