prep1 sc 136 求助(where和each的问题)

ozymendias

It seems likely that a number of astronomical phenomena, such as the formation of planetary nebulas, may be caused by the interaction where two stars orbit each other at close range.

(A) may be caused by the interaction where two stars orbit each other

(B) may be caused by the interaction between two stars that each orbit the other

(C) are because of the interaction between two stars that orbit each other

(D) are caused by the interaction of two stars where each is orbiting the other

(E) are caused by the interaction of two stars orbiting each other

答案是E，我的问题是D中的where怎么错了？笔记上说是没有明确表示地点，stars能算地点吗？
还有each和the other搭配错误，这句话怎么理解啊？？
谢谢大家了~~

where 在GMAT中就是要引导地点的，如果按照你的理解，orbit就发生在stars上，你想象一下这到底是什么情况呢，这些stars在这些stars上转？不makesense；one... the other搭配, 没有each...the other的搭配
