the commission has directed advertisers to restrict use of the word natural to foods that do not contain color or flavor additives, chemical preservatives, or nothing that has been synthesized.
1,or anything that has been
2,and anything
我选的答案是2,正确答案是1,我想问一下,用or是不是因为前面是否定句式do not contain,而需要把and 改为 or
我是这么理解的。。。。理工生的思维请不要介意:
or是或的意思,也就是并集;and是与的意思,也就是交集。
前面有个否定,这里用or就是或非的结构:上划线(A + B +C)
not A, B,or C
则A,B, C 三个中,任意一个不符合条件,则总体不和要求
如果这里是用and的话,就是与非结构,上划线(A*B*C)
全部不满足条件,才总体不和要求。
