标题: 请教OG-V11 14

14. The commission has directed advertisers to restrict the use of the word "natural" 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

Answer Key: D

Answer Explanations: ... Logically, a "natural" food cannot contain any prohibited ingredient, so the list of prohibited ingredients must be connected by or.

我选E。还是不懂为什么这里一定用or而不是and?

or 表示任何一个都不能出现。and表示不能同时出现，但其中某一个不一定不能出现。
