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.

C is the only one that makes sense.

To gain three things are needed:
1. correct signature
2. Signing speed
3. Pen Pressure

C tells us that if only #1 is true, you will not gain access.

Concluding E would be too much from the above argument.

I agree with C.
A, B, D are not true because the passage didn't talked about this issues.
E is probable but very stretched.

Dont you guys think that C is very strong.. "nobody"

E is a lil on the moderate side..where in if a genuine user doesnt gives the same pressure on signatures, he might get rejected..
so E i would choose

Yes, C is way too extreme.

Like fingerprints and personalities, no two signatures are exactly alike.

I`ll bet the farm and my retirement savings on (E).

Yes, C is too extreme.

E is nice/generic and it summarizes the complexity of the program.

I think I understand why C is wrong.

In C the part that got me was "solely by virtue of forging skills". - The argument does not define what exactly forging skills mean.
Although the argument mentiones that even the most adept (known) forgers cannot crack the system, there is still is a possibility that somone named TeHCM, who is from CA, could crack it!

Moreover as you and MATT mentioned, extreme conclusions are not usually right.

OA is 'C'

I picked 'E' too for the same reason that it was extreme. Still not convinced that 'C' is right.

I go with c here. the key here is "most adept forgers" which could mean that guys however skillful at forging the signature itself might not be able to replicate other characteristics such as pressure and speed.

although I do agree that the answer can be extreme- I guess this is the most "logical" conclusion. E talks about denying legitimate access but doesnt encapsulate other poins mentioned in the stem.

dont know how much this make sense - just my two cents.

Choice E is exogenous- it is not directly supported by the passage.

Choice C is the winner by default- "nobody" rightfully raises a red flag but I sensed where the author was going with question

Concluded it was C untill i saw flags being raised. Went back to check the answers and the logic.

Three charecteristics of a signature are given. The form, pen presure and the signing speed with the form being given the importance. The author goes on to say that the most adept forgers cannot duplicate all the three characteristics that the program analyzes for.

C implies that somebody who relies on just forging the signature cannot enter the computer.

Given the answer choices, this is the best one that could be logically concluded.

I have picked the answer C for this question:

From the passage, there are 3 things that the software looks to identify an authentic signature:
1. Form of the signature
2. Pen Pressure
3. Signing Speed

Since the question stem is a MUST BE TRUE question, we can always look back at the passage to clarify our answer choice. I didn't even both prephrasing because there are too many possibilities - in this case I jumped straight into the answer choices.

A. Nowhere in the passage do we talk about the software being impractical for use.

The structure of the argument is:
1. Describes how the software identifies signature
2. Explains how forgers can't duplicate all characteristics to gain access

So, it is clear that this answer choice incorrect.

B. Where do we mention installation of software in most banks? Yea, I thought so...definitely incorrect.

C. This answer choice is correct because it describes how forgers cannot obtain access simply by copying "The form of the signature." In order to get access, you need all 3 components: form, speed and pen pressure.

D. Nowhere do we mention the time it took to develop this software. Incorrect.

E. Although this answer may look correct, there are a few things to mention here:

1. The first 3 words "In many cases," sounds to me like most of the time, authorized users are denied access. This wording is quite strong and I cannot find it anywhere in the passage where users are denied access "in many cases."

2. From the passage, can we even prove that users are ever denied access? There is nothing suggesting that they are ever denied access - this software could be perfect.

Therefore, answer choice E may or may not be true. So, this answer is incorrect.
