OG10--53 请教ETS的解释【sarah归来】

53. 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)    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, o/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 grammati¬cally incomplete. In C, the slowness o/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.

问题：C怎么就改变句意了呢？？换成slowness之后语意变成什么？？

slowness 可以是一直slow
slowing 强调变慢的过程
