大全168，关于than

168.Because the Earth’s crust is more solid there and thus better able to transmit shock waves, an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West.
(A) of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West
(B) of a given magnitude will typically devastate 100 times the area if it occurs in the eastern United States instead of the West
(C) will typically devastate 100 times the area in the eastern United States than one of the comparable magnitude occurring in the West
(D) in the eastern United States will typically devastate an area 100 times greater than will a quake of comparable magnitude occurring in the West
(E) that occurs in the eastern United States will typically devastate 100 times more area than if it occurred with comparable magnitude in the West
the key

why???why not A?what's the problem with A?

is there anything wrong with "it" in A?

a bunch of thanks to whoever relpies!!!

it 和does 都有问题.

用It,  好像一个地震两边忙.
