菜鸟有两道逻辑题不会，跪求NN讲解，同时跪求boldface题突破方法和prep 07的解析

杯杯么么哒

第一道题是prep 07第15题，怎么都想不明白为什么选E
15.   (26883-!-item-!-188;#058&002985)     [GWD #29-Q28]

Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were.  In hopes of gaining some indication of the fragments' size, astronomers studied spectrographic analyses of Jupiter's outer atmosphere.  These analyses revealed unprecedented traces of sulfur after the fragments' entry. The fragments themselves almost certainly contained no sulfur, but many astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up.

In the astronomer's argument, the two portions in boldface play which of the following roles?

(A) The first presents a circumstance for which the astronomer offers an explanation; the second is part of that explanation.

(B) The first acknowledges a consideration that weighs against the conclusion of the argument; the second is that conclusion.

(C) The first acknowledges a consideration that weighs against the conclusion of the argument; the second provides evidence in support of that conclusion.

(D) The first provides evidence in support of the conclusion of the argument; the second acknowledges a consideration that weighs against that conclusion.

(E) The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion

不好意思没有看到 我大概详细给您讲下BF题 其实非常简单  应该是最容易的 有以下几步：
1: 答案只有"一边"  ”两边"  一边就指 两个BF是顺承关系 两边指两个BF是相反的     这个判断很容易：看看从第一个BF第一个词到第二个BF最后一个词之间 有没有 句号+转折词  如果没有就是一边 如果有就是两边  这样就能排除剩下两个或者最多三个选项
2：找文章结论(以此为参照物 判断两个BF的关系  一般 其中一个BF与结论联系很紧密或者就是结论
3：排除 一般就都可以排除出来正确选项

你好 这个答案是E  对吗
