举个例子是答案中注意的问题。 Electrical engineers have repeatedly demonstrated that the best solid-state amplifiers are indistinguishable from the best vacuum-tube amplifiers with respect to the characteristics commonly measured in evaluating the quality of an amplifierâ?s musical reproduction. Therefore, those music lovers who insist that recorded music sounds better when played with the best vacuum tube amplifier must be imagining the difference in quality that they claim to hear.
Which one of the following, if true, most seriously weakens the argument?
(A) Many people cannot tell from listening to it whether a recording is being played with a very good solid-state amplifier or a very good vacuum-tube amplifier.
(B) The range of variation with respect to the quality of musical reproduction is greater for vacuum tube amplifiers than for solid-state amplifiers.
(C) Some of the characteristics that are important in determining how music sounds to a listener cannot be measured.
(D) Solid-state amplifiers are more compact, use less power, and generate less heat than vacuum-tube amplifiers that produce a comparable volume of sound.
(E) Some vacuum-tube amplifiers are clearly superior to some solid-state amplifiers with respect to characteristics commonly measured in the laboratory to evaluate the quality of an amplifierâ?s musical reproduction. 其中, (A) Many people cannot tell from listening to it whether a recording is being played with a very good solid-state amplifier or a very good vacuum-tube amplifier. 光从内容来说,是非常强的weaken,但是A不是标准答案。因为一个单词many,原文中没有数量的限定,但是many是很广泛的一个概念,有可能指music lovers,也有可能不指music lovers,那就会引起歧义了。 A和C要表达的意思差不多,但是就是范围不一致,导致A是错误选项,C是正确选项。 |
