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?
Pre-thinking:Our task is to strengthen the conclusion at hand: "
Thus, visually impaired people can now access information from computers more easily than they can from most traditional sources."
Now, let's find an
assumption and work from there.
Falsification scenario: what if such "right hardwares" are crazy expensive or there are just 10 of them on the planet? Clearly under these circumstances the argument would fall into pieces.
Assumption: Such right hardwares are widely available.
Strengthener: Nowadays people can buy these hardware in any tech-shop at a very convenient price
POE:A) A computerized speech synthesizer is often less expensive than a complete library of audiotapes.
This option does not have any impact on the conclusion for different reasons.
First, it talks only about synthesizers while the conclusion talks about ALL kind of visual impairments.
Second, how much does a complete library of tape cost? Is it crazy expensive or is it quite cheap? From this stand we can either infer that such synthesizers are expensive or cheap. Hence OUTB) 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.
In line with our pre-thought strengthenerC) 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.
IRRELEVANTD) Most visually impaired people who have access to information via computer also have access to this same information via more traditional sources.
IRRELEVANTE) The rate at which printed information is converted into formats easily accessible to visually impaired people will increase.
The conclusion is present-based while this option talks about the future. OUT
