The railway authority inspector who recently thoroughly checked the tracks testified that they were in good condition. Thus, since the inspector has no bias in the matter, we should be suspicious of the newspaper reporter's claim that the tracks are in poor condition.
The reasoning in the argument above is most similar to the reasoning in which one of the following arguments?The argument uses testimony from someone who recently and thoroughly inspected the relevant thing and has no bias. Since that testimony conflicts with another person’s claim, the argument says we should doubt the other claim.
The key pattern is: trust an unbiased inspector’s careful assessment over a
conflicting claim.
(A) My pottery instructor says that making pottery will not cause repetitive-motion injuries if it is done properly. So I will probably not get such injuries, for whenever I do pottery I use the proper techniques that my instructor taught me.
This is not parallel. There is no conflict between two claims, and no unbiased inspector’s assessment is used to reject another person’s claim.
(B) Gardner, a noted paleontologist who has no vested interest in the case, assures us that the alleged dinosaur bones are not old enough to be from dinosaurs. So we should be skeptical of Penwick's claim to have found dinosaur bones, for Gardner inspected the bones carefully.
This is correct. Gardner is an unbiased expert who carefully inspected the bones and reached a conclusion that conflicts with Penwick’s claim. So the argument says we should be skeptical of Penwick’s claim. That matches the original reasoning.
(C) The engineer hired by the company that maintains the bridge has examined the bridge and declared it safe. This engineer is the only one who has given the bridge a close examination recently. Thus, we should consider the bridge safe.
This is not parallel. The engineer may be biased because the engineer was hired by the company that maintains the bridge. Also, the conclusion directly accepts the engineer’s claim, rather than saying we should doubt a conflicting claim.
(D) The reporter who recently interviewed the prime minister said the prime minister appeared to be in poor health. But despite the fact that the reporter works for a paper with opposition leanings, we should accept that the prime minister is in poor health. After all, reporters won't let their bias affect them when the truth of their claims will eventually be discovered.
This is not parallel. This argument asks us to trust a potentially biased reporter. The original argument relies on an unbiased inspector.
(E) The snowblower salesperson claims that there will be above-average snowfall this winter, but because the salesperson is biased, we can discount that claim.
This is not parallel. This rejects a claim because the speaker is biased. The original argument doubts a claim because an unbiased inspector carefully checked the matter and reached the opposite conclusion.
Answer: (B)
