OG11-14

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 synthesized.

(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

The use of do not and nothing in the same sentence creates a double negative and reverses the intended meaning. Anything should be used instead of nothing. Logically, a "natural" food cannot contain any prohibited ingredient, so the
                    list of prohibited ingredients must be connected
                    by or.

A The use of nothing creates a double negative

B That has been synthesized distorts the

meaning by referring to foods, rather than to

something added to a food

C The use of nothing creates a double negative; and should be or

D        Correct. This sentence correctly avoids a double negative and uses parallel elements.

E        And distorts the meaning of the sentence
