Q19:E

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.

1. may include melting the polar ice caps and a rising sea level
2. may include the melting of polar ice caps and the rising sea level
3. may include polar ice caps that are melting and sea levels that are rising
4. include melting the polar ice caps and sea levels that are rising
5. include melting of the polar ice caps and a rise in sea level

答案是E，哪位给分析一下。多谢!

我选的也是B啊。为什么？

E is correct b/c melting and rise are nouns, and are paralleled.

B is not right b/c "B)may include the melting of polar ice caps and the rising sea level"

melting and sea level are not paralleled.

wow! it my honor to answer questions for President Hu.

可是一般情况来说may是不能省掉的是吗？
