41. GWD-23-Q13
Researchers hypothesize that granitic soil is the idealconstruction material for the desert tortoise because it is not so hard thatit makes burrowing difficult or so soft that it could cause tunnels tocollapse.
A. so hard that it makes burrowing difficult or so softthat it could cause
B. hard enough to make burrowing difficult orsoft enough as to cause
C. so hard as to make burrowing difficult orsoft enough so it causes
D. as hard as to make burrowingdifficult or as soft as to cause
E. too hard, making burrowing difficult, nortoo soft, so as to cause
-------------------------------------------------------------------------------------------答案是A
我当时觉得A不是完全对称，so that如果不加情态动词表示结果，so that加情态动词表示目的。 一个表目的和一个表结果的并列就感觉不行。
D刚好完全对称，但又由于as + adj. + as to 到底怎么用。
