1.        Temporary-employment agencies benefit not only from the increasing demand for clerical workers but also the higher profits made when highly paid professionals are placed, requests for whom have increased in the recent wave of corporate takeovers.

(A) the higher profits made when highly paid professionals are placed, requests for whom

(B) the higher profits that are made in the placement of highly paid professionals, requests for whom

(C) from the requests for highly paid professionals, who make higher profits for the agencies when placed and whose requests

(D) from highly paid professionals, whose placement makes higher profits for the agencies and whose requests（E）

(E) from the higher profits made in placing highly paid professionals, requests for whom

选了 D ，因为觉得定从结构很平行。。。D 错是因为改变句意吧：原文不是要表达 professionals' requests, 而是 (sb else ) request for professional.

理解的对吗？期待指正中

D's logic is wrong.

You can't say,   agencies benefit from people [= professionals].

Besides, "professionals" cannot be parallel with "demand".
