When butterfat was considered nutritious and healthful, a law was enacted requiring that manufacturers use the term "imitation butter" to indicate butter whose butterfat content had been diminished through the addition of water. Today, it is known that the high cholesterol content of butterfat makes it harmful to human health. Since the public should be encouraged to eat foods with lower rather than higher butterfat content and since the term "imitation" with its connotations of falsity deters many people from purchasing products so designated, manufacturers who wish to give reduced-butterfat butter the more appealing name of "lite butter" should be allowed to do so.
Which one of the following, if true, most seriously undermines the argument
A．The manufacturers who prefer to use the word "lite" instead of "imitation" are motivated principally by the financial interest of their stockholders.
B．The manufacturers who wish to call their product "fire butter" plan to change the composition of the product so that it contains more water than it now does.
C．Some individuals who need to reduce their intake of cholesterol are not deterred from using the reduced-butterfat product by the negative connotations of the term "imitation."
D．Cholesterol is only one of many factors that contribute to the types of health problems with which the consumption of excessive amounts of cholesterol is often associated.
E．(E) Most people deterred from eating "imitation butter" because of its name choose alternatives with a lower butterfat content than this product has.
参考答案：E
解析： 本题的结论是人们因为“imitation butter”中“imitation”一词的“connotation of falsity”而不敢买具有较低的奶油脂肪含量的“imitation butter”。要削弱上面的论述，就要削弱人们不敢购买的原因。选项(E)通过找他因的办法，说明了人们因不敢吃“imitation butter”而选择使用的替代品的奶油含量比“仿制奶油”的实际含量更低，因此更有利于健康，从而驳斥了将“仿制奶油”改为“清淡奶油”有利于消费者的暗含结论，所以推理成立可能性减少，因此(E)是正确的。(C)易误选，但是(C)选项只是说一些需要减少他们的胆固醇摄入量的人不被“reduced butterfat”产品所具有的“negative connotation”所吓住，这并不能对大多数人不被“negative connotation of the term imitation”所吓住构成反对。
