觉得这个题PREP讲错了

239. (28502-!-item-!-188;#058&003082) (GWD-12-Q3)

Were it not for the fusion-powered heat and radiation that rush from its core, instead its own weight would cause a star to collapse
A. instead its own weight would cause a star to collapse
B. instead a star would have collapsed under its own weight
C. a star would have to be collapsing under its own weight
D. a star would collapse under its own weight
E. its own weight would have caused a star’s collapse

PREP 08 SC E说it指代了its own weight 错误， 我记得manhattan SC 说 it和its在句子中要指代同一个东西啊，那么这里it就是指代star了，这样以来，its own weight也就 make sense 了。 （我知道E错了，但是对这个its和it指代有疑问）
求NN解释~
多谢！

楼主，要养成好习惯，OA是哪一个？

这题明显考虚拟语气倒装。
E选项的主语是后半句its own weight，前面的it自然就指的是这个啦！
E中根本没提到star，就不可能指star了。
楼主是在知道了正确指代之后主观。
