It may someday be worthwhile to try to recover uranium from seawater, but at present this process is prohibitively expensive. (A) It may someday be worthwhile to try to recover uranium from seawater (B) Someday, it may be worthwhile to try and recover uranium from seawater (C) Trying to recover uranium out of seawater may someday be worthwhile (D) To try for the recovery of uranium out of seawater may someday be worthwhile (E) Recovering uranium from seawater may be worthwhile to try to do someday 这一题答案是A，为什么C不可以？ A用it be结构比较罗嗦阿，C简单明了，看上去没什么问题阿。
The suspect in the burglary was advised of his right to remain silent, told he could not leave, and was interrogated in a detention room.

(A) The United States petroleum industry’s cost to meet environmental regulations is projected at ten percent of the price per barrel of refined petroleum by the end of the decade.

(E) It is estimated that by the end of the decade the cost to the United States petroleum industry of meeting environmental regulations will be ten percent of the price per barrel of refined petroleum. 这里为什么一定要换成it is estimated这样罗嗦的结构？B有什么问题么？
