The spraying of pesticides can be carefully
planned, but accidents, weather conditions that could not be foreseen, and
pilot errors often cause much larger deposits of spray than they had
anticipated.

(A)
weather conditions that could not be foreseen, and pilot errors often cause
much larger deposits of spray than they had

(B)
weather conditions that cannot be foreseen, and pilot errors often cause much
larger deposits of spray than

(C)
unforeseeable weather conditions, and pilot errors are the cause of much larger
deposits of spray than they had

(D)
weather conditions that are not foreseeable, and pilot errors often cause much
larger deposits of spray than（B）

(E)
unforeseeable weather conditions, and pilot errors often cause much larger
deposits of spray than they had

这里 unforeseeable 修饰 accidents and weather 两个吗？

i chose E, but ans is B

我认为They指代不清，先排除了A、C和E。对于B、D实在不知怎么选择，最后倒是选了B，但只是觉得它比D更顺口而已。

期待NN的解释！

窃以为accidents 和weather conditions应该是并列关系，所以unforseeable仅修饰weather conditions.

看了将近1分钟选了B速度还是不行...不知道NN花多少时间做好这一题？

A、C和E they没有合理指代对象。

D不对，weather conditions that are not foreseeable没有被动含义。

I think "can't be forseen" is better than "is un....", to show the limited ability.
