Many breakfast cereals are fortified with vitamin supplements. Some of these cereals provide 100 percent of the recommended daily requirement of vitamins. Nevertheless, a well-balanced breakfast, including a variety of foods, is a better source of those vitamins than are such fortified breakfast cereals alone.
Which of the following, if true, would most strongly support the position above?
(A) In many foods, the natural combination of vitamins with other nutrients makes those vitamins more usable by the body than are vitamins added in vitamin supplements.
(B) People who regularly eat cereals fortified with vitamin supplements sometimes neglect to eat the foods in which the vitamins occur naturally.
(C)Foods often must be fortified with vitamin supplements because naturally occurring vitamins are removed during processing.
(D) Unprocessed cereals are naturally high in several of the vitamins that are usually added to fortified breakfast cereals.(A)
(E) Cereals containing vitamin supplements are no harder to digest than similar cereals without added vitamins.
这句话我觉得像是Lawyer说的前提和结论关系不密切,直接加强结论。选项A在加强了作者better source这样的结论。也就是像OG解释中所说的:adds support for the alleged advantage of a well-balanced breakfast over fortified cereal. 前面两句话是对breakfast cereals fortified with Vitamin supplements 的说明,是事实。记得还有几个相似的例子。前面两句话提供背景,然后结论里面也就是Neverthless后面有概括性词汇比如Such。那么要削弱是不能削弱前面两句话的。
