[求助]大全 25：分词短语到底修饰谁？

gmat700+

      A recent study of ancient clay deposits has provided new evidence supporting the theory of global forest fires ignited by a meteorite impact that contributed to the extinction of the dinosaurs and many other creatures some 65 million years ago.

(A) supporting the theory of global forest fires ignited by a meteorite impact that

(B) supporting the theory that global forest fires ignited by a meteorite impact

(C) that supports the theory of global forest fires that were ignited by a meteorite impact and that

(D) in support of the theory that global forest fires were ignited by a meteorite impact and that（B）

(E) of support for the theory of a meteorite impact that ignited global forest fires and

这道题答案我选对了，但是我的想法和白勇讲的不一样，就是关于 contributed…… 这个分词短语修饰谁的问题。我觉得 contributed to the extinction of the dinosaurs and……是就近修饰 a meteorite impact 的，而白勇说是修饰 global forest fires 的。他说是全球的森林大火导致 the extinction of the dinosaurs，而不是 meteorite impact导致恐龙灭绝。但是按照分词短语就近修饰原则，难道不是 meteorite impact 导致 the extinction of the dinosaurs 吗？

请牛牛们指点一下！

global forest fires ignited by a meteorite impact是主语，ignitedby是过去分词作定语，contributed to是谓语。你可能把contributed to理解成过去分词了。

1，vi:contribute to sth:导致，促成，使发生。

2，vt:contribute sth t给...,捐sth，贡献sth。

所以sth contributed to sth/sb很容易被理解成 2的被动形式，但这样句子就没有谓语了。

哦！哎呀，我真是笨死了。谢谢牛牛！

supporting the theory that global forest fires（主语） (ignited by a meteorite impact  修饰fires)contributed（谓语） to the extinction of the dinosaurs and many other creatures some 65 million years ago.

阴险啊。

如果这么一解读，的确是B最简洁，清晰
