大全-3-13

我笨，我努力

Record companies defend their substitution of laser-read compact discs (CD’s) for the much less expensive traditional long-playing vinyl records in their catalogs by claiming that the audio market is ruled by consumer demand for ever-improved sound reproduction rather than by record manufacturers’ profit-motivated marketing decisions. But this claim cannot be true, because if it were true, then digital audiotape, which produces even better sound than CD’s, would be commercially available from these same record companies, but it is not.

13.   Which of the following, if true, would most strengthen the argument against the record companies’ claim?

         (A) When CD’s were first introduced in the audio-reproduction market, prices were high and selection    was poor.

(B) Record companies are reluctant to attempt commercial production of digital audiotape until profits from the sales of CD’s have enabled them to recover their investments in compact-disc manufacturing technology.

(C) Some CD’s have been so much in demand that consumers have experienced long delays in obtaining copies.

(D) Because CD’s work according to principles very different from those that govern conventional recordings, commercial production of CD’s requires new kinds of manufacturing technology.（B）

(E) Any valid comparison of CD audio reproductions to digital audiotape reproductions must be based on identical performances played back on the highest quality disc or tape player.

题目是要找：支持原文中削弱the record companies’ claim的选项。

我觉得B：当投资CD技术有回报的时候再去发展 digital audiotape ，就是说CD技术可以发展，正好是支持companies’claim的。B为什么对？

我的想法错在哪里呢？

题干中record company的claim是在辩解他们生产CD并不是为了利益，否则他们完全可以生产音质更好的digital audiotape。

B的意思其实是在说record company不会尝试生产digital audiotape，除非他们通过CD来赚取补偿他们在CD生产技术上的投资。那么正好说了CD对于这些公司来说是有利可图的，并不是他们所说的那样不是为了利益。

你的想法是错误理解了company的claim，他并不是说CD技术可不可以发展，而是说他们再为自己辩解：生产CD并不是为了利益。那么就要从这里着手。

还是那句话，读逻辑题一定要每个字都看透！

请指教！

谢谢，arundhati！我会努力提高的！
