标题: 求教：旧prep-2-111（现在分词作伴随）

Astronomers have uncovered evidence that a star that was as bright as the full moon exploding into

view 340,000 years ago, emitting dazzling radiation that could have disrupted Earth's protective

ozone layer and sunburned our Stone Age ancestors.

(A) that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting

(B) that a star as bright as the full moon exploded into view 340,000 years ago, emitting

emitted

(D) of a star as bright as the full moon, exploding into view 340,000 years ago and emitting

(E) of a star as bright as the full moon that exploded into view 340,000 years ago and that emitted
答案是B。
我想问的是，emitting在句尾可以做伴随修饰 that a star...从句，而不会产生修饰主语Astronomers have uncovered .的歧义吗？

以下引用Ron的解释：（http://www.manhattangmat.com/forums/astronomers-have-uncovered-evidence-that-a-star-that-t4483.html）

in general, a COMMA -ING modifier modifies the subject and action of the DIRECTLY PRECEDING CLAUSE. if the preceding clause contains another, embedded sub- clause, which runs all the way to the conclusion of that clause, then the modifier may modify EITHER that sub-clause OR the entire surrounding clause.
as is the case with many of these things, you must use CONTEXT to tell the difference. if either of these interpretations makes sense, then you must count the sentence as legitimate.

in this case, "emitting" modifies the subject and action of
a star as bright as the full moon exploded into view 340,000 years ago
... a modification that makes perfect sense.

句尾的现在分词既可能修饰前面的主句，也可能修饰前面主句中嵌套的从句，这种情况出现时，就根据逻辑意思判断，只要任何一个可能说得通，就算正确。

恩，B有这个问题，但是还能解释的通。
重要的是，别的选项有严重的错误，更加不好。
