《逻辑推理》中的一道难题 请教各位牛人们！！！

1.Masterpieces of literature are "intertextual",that is, they tend to be written in response not to reality but to other works of literature. To the extent that a writing is intertextual, it becomes clouded as a mirror of social reality.

The statements above provide the most support for which of the following conclusions?

A. To the extent that a writing fails to mirror social reality, the writing is intertextual.

B.The author who wishes to write a masterpiece should aviod being influenced by other works of literature.

C.A writing that is not intertexual can have no significant relationship to any other writings.

D.Literaray masterpieces of the past are suspect as sources of information about the social reality of the past.

E.A work of literature is not intertexual if it is written in response to a writing that accurately mirrors social reality.

对于这一题，A，B，E 答案我已经排除了，可是不明白为什么C错？ D又是从哪里得出来的呢？

我已经纠结了好几天啦，希望各位能给我详细的解答，如果可以画出逻辑推理图最好。

谢谢！！！

我说人会跨栏，Ａ是人，结论Ａ会跨栏．如果问你，Ｂ不是人，Ｂ会不会跨栏是无从推导的．

否定结论的推出必须要有否定的依据．

所以Ｃ不是结论．

谢谢啦，那D是怎么推出来的啊？

肯定推不出否定不时觉得的 如果原文出现了ONLY ALL 这样的绝对字眼你也要小心又些否定也是可以的

只有A会跨栏 ,B不是A 结论B 不会跨栏

D选项,关注最后一句To the extent that a writing is intertextual, it becomes clouded as a mirror of social reality.

Literaray masterpieces (of the past) are suspect as sources of information about the social reality( of the past).

括号里的去掉跟原文的思路一致,只是新的元素即括号里的出现了而已.
