又一个小白的问题

Not all employment selection mechanisms that have a “disparate effect,” that is, that screens out a percentage of minorities or women disproportionate to their presence in the relevant labor market, are unlawful.

(A) that is, that screens out a percentage of minorities or women disproportionate to

(B) which means, that screens out a percentage of minorities or women disproportionate with

(C) which means, that screen out a percentage of minorities or women disproportionate with

(D) that is, that screen out a percentage of minorities or women disproportionate to（D）

(E) that is, that screens out a percentage of minorities or women disproportionate with

我是如何也不明白，that后面引导的从句不是修饰effect的么？为什么还要用复数形式呢？

screen out is used to modify the mechanism .not the effect.

Because only the meachnism can screen out ..., while the effect cannot screen out .....

从逻辑上说是，可是这个结构是怎么回事呢？

cranberry: 这是一道跳跃修饰的一题 你可以查一下OG中的古家具那题 也是跳跃修饰 希望能有启发

究竟修饰谁 两个办法

1一定要根据意思来判断

2可根据主谓一致 因为mechanisms 是复数 只能用复数

那后面这个that is 是什么成分呢？that指的是什么？
