crossroad

Q38:

Imported into Massachusetts form Europe in 1869, the gypsy moth was used by a French

scientist in an attempt at developing a strong strain of silk-producing insects, crossing

gypsy moths with adult silkworms.

A. Imported into Massachusetts from Europe in 1869, the gypsy moth was used by a

French scientist in an attempt at developing a strong strain of silk-producing

insects, crossing gypsy moths with adult silkworms.

D. The gypsy moth was imported into Massachusetts from Europe in 1869 by a

French scientist attempting to develop a strong strain of silk-producing insects by

crossing gypsy moths with adult silkworms.

答案是D.

我选A

之前只有一个贴子, 可我还是不懂.

(1)如果是D, D是不是表示科学家引进的MOTH? A是说科学家使用MOTH.
(2)选D的人主要有两个理由:

A中的CROSSING 不对, 可是CROSSING可以修饰DEVELOPING呀

attempt at　不对，　可是也有人查字典说可以．

我就是想知道，　原文到底是想说科学家引进还是科学家使用．
