The ability to access information via computer is a tremendous resource for visually impaired people. Only a limited amount of printed information is accessible in braille, large type, or audiotape. But a person with the right hardware and software can access a large quantity of information from libraries and museums around the world, and can have the computer read the information aloud, display it in large type, or produce a braille version. Thus, visually impaired people can now access information from computers more easily than they can from most traditional sources.

Which one of the following, if true, most strengthens the argument?

A) A computerized speech synthesizer is often less expensive than a complete library of audiotapes.

B) Relatively easy-to-use computer systems that can read information aloud, display it in large type, or produce a braille version of it are widely available.

C) Many visually impaired people prefer traditional sources of information to computers that can read information aloud, display it in large type, or produce a braille version of it.

D) Most visually impaired people who have access to information via computer also have access to this same information via more traditional sources.

E) The rate at which printed information is converted into formats easily accessible to visually impaired people will increase.

"B". The passage also specifies that "limited" information is available on audio-tapes. A is out.

This Q is from Franklin's Super-Fly Critical Reasoning Question Thread
narrowed down to A & B
but will choose A in the exam
please explain ur answers

Note : even i do not know the Answer

thanku for the explanations getmba

I believe it is B.

The passage states that traditional sources for the impaired are limited. Combine this with the wide availability of computers (choice B), and the author's argument that visually impaired people can access information more easily with computer systems is strengthened.

There is a logical connection between the conclusion and the assumption at B:
"visually impaired people can now access information from computers more easily" because "relatively easy-to-use computer systems ... are widely available".

hence, B does stregthen.

Stimulus says the functionalities of the computer systems are helpful to the visually impaired. Answer choice B says they are readily available. So that makes useful information easily available to visually impaired. Since nothing is mentioned about cost, choice A is out of scope.

B is my pick.
