GWD13-2-19:
Possible long-term consequences of the “greenhouse effect,” the gradual warming of the Earth’s climate, may include melting the polar ice caps and a rising sea level.

A. may include melting the polar ice caps and a rising sea level
B. may include the melting of polar ice caps and the rising sea level
C. may include polar ice caps that are melting and sea levels that are rising
D. include melting the polar ice caps and sea levels that are rising
E. include melting of the polar ice caps and a rise in sea level
   Key：E
怎么会选E呢，它去掉了可能性惯词may改变拘役，而且and前后不对陈。我选B。请牛牛们指点。

这个may和前面的possible重意了, 所以要省.

B虽然貌似平行, 但仔细看, B把melting 和 sea level平行了. E中至少还是把melting 和a rise两个动作性的名词平行了.
