问题     Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated.  Advocates of organic foods — a term whose meaning varies greatly — frequently proclaim that such products are safer and more nutritious than others.
    The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and from the basis for folklore.
    Almost daily the public is besieged by claims for "no aging" diets, new vitamins, and other wonder foods. These are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains, and the like.
    One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is a real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
The word "advocates” in the first paragraph is closest in meaning to which of the following?
选项 A、Consumers.
B、Merchants.
C、Inspectors.
D、Proponents.
答案D
解析 语义理解题。 根据上下文不难判断其意思。文章一开始提出问题：施加有机肥料生长的食物是人类的最佳选择吗?接着指出：这种认为有机肥料优于普通生长并销售的食物的观点正逐渐引起争议。而紧接着的Advocates所在的句子中，谓语 proclaim引导的宾语从句，即Advocates的意见，显然与前一句claim(与 proclaim同义)后的宾语意思一致，是对文章开始提出的问题的肯定回答。故D“支持者”正确。
