The companies that are the prime purchasers of computer software will not buy a software package if the costs of training staff to use it are high, and we know that it is expensive to teach people a software package that demands the memorization of unfamiliar commands. As a result, to be successful, commercial computer software cannot require users to memorize unfamiliar commands.
The conclusion above follows logically if which one of the following is assumed?
(A) If more prime purchasers of computer software buy a software product, that product will successful.
(B) Commercial computers software that does not require users to memorize unfamiliar commands is no more expensive than software that does.
(C) Commercial computer software will not be successful unless prime purchasers buy it.
(D) If the initial cost of computer software is high, but the cost of training users is low, prime purchases will still buy that software.
(E) The more difficult it is to learn how to use a piece of software, the more expensive it is to teach a person to use that software.
Very little is gained from refuting OA's from
OG, GPrep, LSAT.
OA is indeed "C", and it is correct. We just have to justify how?
Premise:
Prime purchasers won't BUY a software that requires expensive training.
Expensive training is required for teaching UNFAMILIAR commands of a software.
Conclusion:
To be SUCCESSFUL, our software must not require users to learn unfamiliar command.
A proper conclusion would have been:
To make prime purchasers buy our software or at least consider buying, we must not require the users of the software to learn unfamiliar command.
Why?
Because, that will make sure that the training is not expensive. If the training is not expensive, companies will consider buying.
So far just BUYING is concerned, the conclusion holds good. However, the conclusion takes a leap ahead. It says, "TO BE SUCCESSFUL". Note: "To be successful" IS NOT NECESSARILY analogous to "to sell the products to prime purchasers", yet the conclusion mistakenly associated the selling with the success.
C says just that:
(C) Commercial computer software will not be successful unless prime purchasers buy it.
(B) Commercial computers software that does not require users to memorize unfamiliar commands is no more expensive than software that does.
Even if we take this into consideration, it will not justify the success. Moreover, we know the cost of the software is not the issue; at least, not according to the passage. It is the training cost/unfamiliar command that matters.
(E) The more difficult it is to learn how to use a piece of software, the more expensive it is to teach a person to use that software.
Using a software is vaguely/remotely related to difficulty associated with learning unfamiliar command. This is out of scope.
Ans: "C"
