Ron网课的平行修饰问题

HYBkkk

请问一下Ron在2010-1-21的网课里举了两个例子
1. Hand signs that native use and that appear in local rituals. (T)
2. Many of the dioxins that are currently uncontrolled and North Americans are exposed to come. (F)
Ron 说第二个句子and两遍都是modifier修饰dioxins但因为and的右边subject是North Americans左边没有subject所以错误。 那为什么1在这里就可以呢

and 连接的平行结构，要注意修饰时的位置。
