标题: LSAT-2-2-11: Please help analyze this question

11.“If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.

“So all that is needed to save the koala is to stop deforestation,” said the politician.

Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?

(A) Deforestation continues and the koala becomes extinct.

(B) Deforestation is stopped and the koala becomes extinct.

(D) Deforestation is slowed and the koala survives.（B）

(E) Deforestation is slowed and the koala approaches extinction.

I totally have no idea for this problem. How do you analyze it? Why the answer is B? How come "Deforestation is stopped and the koala becomes extinct." is consistent with the biologist's claim?

Thank you.

唉，我搜过了，没搜到啊！我分别用L2、L 2、L2-2做关键字都没搜到。

而且，很多题我按照置顶贴里的写的搜索规则都搜不到。

原文：B：Deforestation推出Extinction

P：否Deforestation推出否Extinction（实为B的否命题）

问题要你找选项与B不矛盾（BE CONSISTENT WITH），与P矛盾。

答案B：否Deforestation和Extinction并存。这和P矛盾，和B不矛盾（因为否命题和原命题不矛盾，否命题不一定错）

以下是引用lawyer_1在2004-9-16 0:06:00的发言：

原文：B：Deforestation推出Extinction

P：否Deforestation推出否Extinction（实为B的否命题）

问题要你找选项与B不矛盾（BE CONSISTENT WITH），与P矛盾。

答案B：否Deforestation和Extinction并存。这和P矛盾，和B不矛盾（因为否命题和原命题不矛盾，否命题不一定错）

这道题脑筋转不过来, 为何Biologist: deforestation-->extinct和答案B: stop deforestation--->extinct是不矛盾的呢?

另外, A为什么错?
