The commission has directed advertises 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.
(D) or anything that has been
(E) and anything
答案为Ｄ。解释说是用ｏｒ表其中一个条件，而不是用ａｎｄ表所有条件。
１．如何判断什么时候用ｏｒ，何时用ａｎｄ？
２．anything that has been 中完成时依据是什么？为何不用anything( that is) synthesized?
