14. The commission has directed advertisers to restrict the use of the "word" to foods that do not contain color or flavor additives, chemical preservatives, or nothing that has been sythesized.

A) or nothing that has been

B) or that has been

C) and nothing that is

D)or anything that has been

E)and anything

official guide 的答案是D。

虽然是平行结构，但是我想问一下，它的平行部分是 noun or noun, noun, or noun.

这种结构比较少见，正常是

1)noun, noun, noun, or noun

2)noun , or noun , or noun, or noun.

请nn 讲讲

不是NN, 我想可能是这样吧

do not contain (color or flavor additives), (chemical preservatives), or (anything that has been sythesized).

同意这个看法，此题不是平行结构吧

平行结构不仅仅看形式，更重要要注意逻辑意义上是否也构成平行，OG当中这样的陷阱很多的。大家小心哦！！

呵呵！
