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
答案选E
不是不可以随便去掉情态动词may么？还有melting of the polar ice caps 和a rise in sea level也不平行对称啊？我选的是B

初次准备G,望得高人好心指点一二，谢谢

酱子啊

possible 和may  你不觉得重复了吗 ，累赘。排除ABC。E 的选项melting of the polar ice caps 和a rise in sea level是平行的。Melting是名词，不是动名词。和rias平行的
