There is no consensus on what role, if any, is played by acid rain in slowing the growth or damaging forests in the eastern United States.

(A) slowing the growth or damaging

(B) the damage or the slowing of the growth of

(C) the damage to or the slowness of the growth of

(D) damaged or slowed growth of（E）

(E) damaging or slowing the growth of

The corrected sentence must make clear that both damaging and slowing the growth of refer to forests. E is the only choice that does so without introducing errors. In choice A, of is required after growth. In choices B and C, the use of the damage instead of damaging produces awkward and wordy constructions, and without to after damage, B is grammatically incomplete. In C, the slowness
                            of does not convey the original sense that the rate of growth has been slowed by acid rain. Choice D also changes the meaning of the sentence by making both damaged and slowed refer to growth.

这ETS不是搬石头砸自己的脚吗？og解释的最后一句刚说了damage 和slow都是指growth，可是又说E是对的。D和E里面的damage、slow除了形式不同，有区别吗？
