单选题 At the Shadybrook dog kennel, all the adult animals were given a new medication designed to reduce a dog's risk of contracting a certain common infection. Several days after the medication was administered, most of the puppies of these dogs had elevated temperatures. Since raised body temperature is a side effect of this medication, the kennel owner hypothesized that the puppies elevated temperatures resulted from the medication's being passed to them through their mothers' milk.
Which of the following, if true, provides the most support for the kennel owner's hypothesis?

A、 Some puppies have been given the new medication directly but have not suffered elevated temperatures as a side effect.
B、 The new medication has been well received by dog breeders as a safe and effective way of preventing the spread of certain common canine infections.
C、 None of the four puppies in the kennel who had been bottle-fed with formula had elevated temperatures.
D、 An elevated temperature is a side effect of a number of medications for dogs other than the new medication administered at the kennel.
E、 (E) Elevated temperatures such as those suffered by most of the puppies in the kennel rarely have serious long-term effects on a puppy's health.

【正确答案】 C

【答案解析】[解析] 本题问题目的明确，让我们支持养狗场场主的假设，所以读题重点放在最后一句话上，即体温上升是由于这种药通过幼狗母亲的乳汁进入了幼狗体内。选项(C)指出当狗用奶瓶喂养时没有体温上升，属于典型的“无因就无果”类的支持，即没有通过幼狗母亲的乳汁喂养就没有体温上升这个结果。(A)中的some说明不了段落中的most of the puppies of these dogs的情况；(B)饲养员的看法与上述假设无关；(D)为明显反对；(E)为无关选项。
