17. In the mid-1960's a newly installed radar warning system mistook the rising of the moon as a massive missile attack by the Soviets.

   rising of the moon for a massive Soviet missile attack

(D)
   moon as it was rising for a massive Soviet
    missile attack

(E)

    attack
    

OG的解释上说for a more concise expression ,the phrase by the Soviets may be condensed to the adjective Soviet, placde before missile attack 这个就不懂了 不是说A+ prep.+B的结构要由于AB的结构的吗（）因为表达更准确？为什么这里 a massive missile attack by the Soviets 就没有 a massive Soviet missile attack 好呢？

17题：

解释上有说：The sentence should read：the system mistook the rising of the moon(x)for a massive missile attack(y)， For a more concise expression of y，the phrase by the Soviets may be condensed to the adjective Soviet，placed before missile attack．
