Unplugging a peripheral component such as a “mouse” from a personal computer renders all of the software programs that require that component unusable on that computer. On Fred’s personal computer, a software program that requires a mouse has become unusable. So it
must be that the mouse for Fred’s computer became unplugged.
The argument is most vulnerable to which one of the following criticisms?
(A) It contains a
shift in the meaning of “unusable” from “permanently unusable” to “temporarily unusable.” - WRONG. Irrelevant. No such distinction is possible.
(B) It treats an event that can cause a certain result
as though that event is necessary to bring about that result. - CORRECT. See the word 'must' which suggests so.
(C) It introduces information
unrelated to its conclusion as evidence in support of that conclusion. - WRONG. Not unrelated but used illogically.
(D) It attempts to support its conclusion
by citing a generalization that is
too broad. - WRONG. Generalization is fine but why use 'broad'. Aren't the two same? But most importantly had it been about generalization words like 'must' which suggest specificity would not have been used. Thus, 'generalization' and 'broad' are wrongly used as they are going in the opposite direction of passage.
(E) It overlooks the possibility that
some programs do not require a peripheral component such as a mouse. - WRONG. Not concerned with programs that don't require component.
Answer B.
