lzm 9-9
During the 1980s it became clear that soliciting private funds was far more efficient for environmentalists who sought financial aid than to go to state or federal agencies.

B. that for environmantalists who sought financial aid, it was far more efficient to solicit private funds
C. that for environmentalists seeking financial aid, private organizations were far more efficient to go to

Key: B,   但我觉得C好，因为B中“it was far more efficient to solicit private funds”好像解释不通啊。
