    The growing interest of【C4】______in the safety and nutritional quality of the typical North American diet is a welcome development.【C5】______，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【C6】______are not supported by scientific evidence，the preponderance(优势)of written material【C7】______such claims makes it difficult for the general public to separate fact from【C8】______．As a result，claims that eating a diet【C9】______entirely of organically grown foods prevents or【C10】______disease or provides other benefits to health have become widely【C11】______and form the basis for folklore．Almost daily the public is【C12】______by claims for“no-aging”diets，new vitamins and other【C13】______foods．There are numerous unsubstantiated reports that【C14】______vitamins are superior to synthetic ones，that fertilized eggs are nutritionally【C15】______than unfertilized eggs and the【C16】______．

选项 A、attacked
B、embraced
C、wrapped
D、besieged
答案 D
解析 语义衔接题。本句承接上一句，讲述只食用有机食品就能防治疾病或增进健康的断言被广泛宣扬所自然导致的结果。选项A) attacked“攻击”，公众受claims的攻击，含有贬义倾向，与文意不符；选项B) embraced“拥抱，环绕”，是褒义词，而从文中我们可以看到作者只是对这些claims做出客观评价，无褒贬之分，所以排除;选项C) wrapped“包裹”，语义不符，不能说公众被claims包裹着；选项D) besieged“包围，困扰”符合文意。所以答案是D) 。
