[求助]急问一题！！

没办法1987

We can learn about the living conditions of a vanished culture by examining its language. Thus, it is likely that the people who spoke Proto-Indo-European, the language from which all  Indo-European languages descended,lived in a cold climate, isolated from ocean or sea, because Proto-Indo-European lacks a word fpr "sea", yet contains word for "winter", "snow", and "wolf".

Which one of the following, if true, most seriously weakens the argument?

A) A word meaning "fish" was used by the people who spoke Proto-Indo-European.

B) Some languages lack words for prominent elements of the environments of their speakers.

C) There are no known languages today that lack a word for "sea".

D) Proto-Indo-European possesses words for "heat".

E) The people who spoke Proto-Indo-European were nomadic.

ans:B

D为何不对啊？

1.从问题的“weaken"可以看出本题是典型的削弱提。答案就是要找和原文中结论相反的选项

本文主题是通过研究其语言，我们能够了解一种消失的文化的居住环境。

我们要在答案中找的就是相反的结论，可以削弱这个命题的结论

选项D) Proto-Indo-European possesses words for "heat".原文中并又有提到“heat"，实际上这是一个无关选项，选它不能削弱文中的结论。
