The Dvorak keyboard requires less finger movement than the ubiquitous QWERTY keyboard. As a result, Dvorak keyboard users are not only able to type more words per minute, but are also less vulnerable to both repetitive stress disorder and carpal tunnel syndrome. Nonetheless, businesses, as well as consumers, have not adopted the Dvorak keyboard. Clearly, if the Dvorak keyboard is to become more widely used, its benefits must be more widely touted.

Which of the following, if true, casts the most doubt on the author’s conclusion?

A) The initial cost of manufacturing a Dvorak keyboard will be more expensive than that of a QWERTY keyboard.
B) Many who have attempted using a Dvorak keyboard claim that learning the configuration of keys takes weeks
C) Those suffering from repetitive stress injuries often attribute the injuries to multiple factors
D) Businesses that have educated employees on the benefits of the Dvorak keyboard, have found that employees continue to use the QWERTY keyboard
E) Businesses have found that many employees who believe the QWERTY keyboard is responsible for stress-induced injuries are unaware of the Dvorak keyboard.

As per option D, people who were trained in the DVORAK keyboard continued to use the QWERTY keyboard. This shows that there are factors not discussed which give the QWERTY keyboard thumbs up and more advantages.

Hence D rightly casts doubt on the conclusion that if they DVORAK keyboard was more widely used,it will become touted widely.

Although I got the right answer, but I'm still wondering why B is entirely wrong? It does give another reason as to why the QWERTY keyboard is preferred over the other.

Hi,

If B does something then all that it does is that learning the DVORAK keyboard is not so easy, since it takes weeks and not days.

Also being able to learn the usage is completely different from using the keyboard( to such an extent that it is preferred over QWERTY) . Kind of out of context because there is no direct meaning out of it.

I have put my reasoning for D as well in the above post.

Hope its clear?

Regards,
Dom.

Even C is a contender because it says reasons for injuries are of other factors not only due to key board, so even the benefits are widely popular will not help to avert the usage of QWERTY keyboard.

Can some one help why C is not the perfect weakener.

Hi,
    Answer Choice (C) is telling about suffering from repetitive stress injuries,in which Dvorak keyboard users are less vulnerable(than QWERTY Keyboard users).It actually Strengthened the idea that Dvorak keyboard is better than QWERTY keyboard.

    Thanks

Official Explanation


This argument, quite specifically, is that: if more people knew about the benefits of the Dvorak keyboard, more people would use it. In other words, it's purely an information problem: people don't use the Dvorak keyboard simply because they don't have the proper information about it.

Choice (D) is the credited answer. If businesses have educated their employees about these benefits, then the people know about them; if people who understand the benefits of the Dvorak keyboard still continuing using the QWERTY keyboard, then information alone is not the issue. Something else is preventing the transition to the Dvorak keyboard. This contradicts the argument, so this is a valid weakener.

Cost is irrelevant to whether employees (people who don't pay for the keyboards!) will use it. Choice (A) is irrelevant and incorrect.

How much time the Dvorak keyboard takes to learn may discourage a few, but presumably the threat of major injuries such as repetitive stress disorder and carpal tunnel syndrome would be enough for most people to overcome a little inertia. Choice (B) is not a particularly powerful weakener, so it is incorrect.

It may be that repetitive stress injuries have multiple causes, but if I had an repetitive stress injury, and I knew the condition was caused by, say, four different things, wouldn't I be motivated to eliminate any one of those four causes? If I found out, by switching keyboards, I could entirely eliminate one possible cause, wouldn't that be a significant inducement to do so? Choice (C) certainly is not a weakener, so it is incorrect.

If some people believe in problems with the QWERTY keyboard, and are unaware of the Dvorak keyboard, then it sounds very much as if a lack of information is the problem. Choice (E) is an extraordinary strengthener for the argument, but we need a weakener. Choice (E) is incorrect.
