答案是C，我选D。 C中明显主（fossils)谓(was)不一致呀。请指教。
I agree D, too, but to make my understanding right and clear, I would like to present my reasoning as following, hoping to get comment from xDJM.\
For A, " found ..." acts as an attributive and directly modifies the closest word, "sloth", so no matter whatever information follows, the sentence is logically flaw because it implies that the sloth found in 1991 have been became fossils. incredible!
but D, "found ..." acts as an adverbial, modifies fossils, the subject of main sentence.
In C, the that clause "sloth that..." produce the same logic flaw as the "found ..." in A.
E is not so clear and concise.
D is the best. |
