possibility of doing vs. possibility to do

想请问一下以上两者有什么区别呀？

欧的理解

possibility of doing  重心在于 possibility 强调可能性

possibility to do 重心在于 to do 强调做什么

谢谢版主的回答，我其实在问的是这个题

The expected rise in the price of oil could be a serious impact to industrialized nations and severely diminish the possibility to have an economy free of inflation.

(A) be a serious impact to industrialized nations and severely diminish the possibility to have

(B) seriously impact on industrialized nations and severely impede the possibility to have

(C) seriously impact on industrialized nations and severely impede the possibility of having

(D) have a serious impact on industrialized nations and severely impede the possibility to have（E）

(E) have a serious impact on industrialized nations and severely diminish the possibility of having

因为搞不明白D与E有何区别，方才问的。不过我还不是很清楚你要说的，能不能再解释一下，谢谢谢谢！！

diminish the possibility

'impede' is not proper. 请参阅
