5. The museum's night security guard-maintains that the thieves who stole the portrait did not enter the museum at any point at or above ground level. Therefore, the thieves must have gained access to the museum from below ground level.
The flawed pattern of reasoning in the argument above is most similar to that in which one of the following?
(A) The rules stipulate the participants in the contest be judged on both form and accuracy. The eventual winner was judged highest in neither category , so there must be a third criterion that judges were free to invoke.
(B) The store's competitors claim that the store in selling off the shirts at those prices, neither made any profit nor broke even. Consequently, the store's customers must have been able to buy shirts there at less than the store's cost.
(C) If the census is to be believed, the percentage of men who are married is higher than the percentage of women who are married. Thus, the census must show a higher number of men than of women overall.
(D) The product label establishes that this insecticide is safe for both humans and pet. Therefore, the insecticide must also be safe for such wild mammals as deer and rabbits.
(E) As had generally been expected, not all questionnaires were sent in by the official deadline. It follows that plans must have been made for the processing of questionnaires received late.
答案是B， 不过我没看出原题和B的flaw在哪里？各位指教一二！ |
