老题目有不解的地方

The spraying of pesticidescan be carefully planned, but accidents, weather conditions that could notbe foreseen, and pilot errors often cause much larger deposits of spray thanthey had anticipated.

A.   weather conditions that could not beforeseen, and pilot errors often cause much larger deposits of spray than theyhad

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

C.   unforeseeable weather conditions, and piloterrors 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

E.    unforeseeable weather conditions, and piloterrors often cause much larger deposits of spray than they had

这个题目的B选项，我不明白为什么要that ，因为我觉得这个地方有点问题，but 应该链接是句子，这个用that 相当于名词，直接不用that 这个句子其实也是可以成立的，相当于说前面balabala 然后后面一个转折，一个是accidents, weather conditions 问题，然后是pilot errors 的问题，用了that直接让我感觉这个地方让我不解，求大虾来解释

其实这题的结构很清楚
句子1, BUT 句子2(A, B, and C cause ...)
that could not be foreseen 是作为从句修饰前面的weather conditions的
三个名词accidents, weather conditions和pilot errors 是句子2中并列的主语，共同cause larger deposits
