A worker for a power company
trims the branches of trees that overhang power lines as a
prevention against damage to the lines anticipated
because of the impending stormy season. The worker reasons that there will be no need for her to trim the overhanging branches of a certain tree because the owners of the tree have indicated that they might cut it down anyway.
Which one of the following decisions is based on flawed reasoning that is most similar to the worker’s flawed reasoning?
(A) A well inspector has a
limited amount of time to
inspect the wells of a town. The inspector reasons that the wells should be inspected in the
order of most used to least used, because there might
not be enough time to inspect them all. - WRONG. Reasoning seems valid as its not dependent.
(B) All sewage and incoming water pipes in a house must be
replaced. The plumber reasons that the cheaper polyvinyl chloride pipes should be used for sewage rather than copper pipes, since the
money saved might be used to
replace worn fixtures. - WRONG. Nothing matches the passage flow.
(C) A mechanic must
replace the worn brakes on a company’s vans that are
used each weekday. The mechanic reasons that since one of the vans is tentatively scheduled to be junked, he
will not have to replace its brakes.
(D) A candidate decides to
campaign in the areas of the city where the
most new votes are concentrated. The candidate reasons that campaigning on other areas is unnecessary because in those areas the candidate’s message is actually
liable to alienate voters. - WRONG. Alienation is independent of the area.
(E) None of the children in a certain kindergarten class will take
responsibility for the crayon drawing on the classroom wall. The teacher reasons that it is best to keep all the kindergarten children in during recess in order to be certain to punish the one who did the drawing on the wall - WRONG. Like A, this is also reasonable.
The three key aspects are highlighted in blue text in the passage. Worker reasons to not cut because owners would cut the branches. Certainly there's some assumption in the worker's decision which may falter. This likely faltering scenario is flawed in itself as it's dependent in nature.
Answer C.
