问题 单项选择题

科学家对76位心脏病患者进行了研究,他们分别采用“一名志愿者带一只狗前去探望病人”、“一名志愿者前去探望病人”以及“没有志愿者”三种方法分别测试这些病人的反应。结果发现第一种情况下病人的焦虑程度下降了24%,第二种情况下病人的焦虑程度只下降了10%,第三种情况下病人的焦虑程度仍保持原来水平,因此科学家认为,狗能帮助心脏病人降低焦虑情绪。下面哪一项最能削弱科学家的论点?

A.带狗和不带狗探视的实验分别选在两个不同的时间段

B.在带狗的志愿者中,绝大多数喜欢并自己饲养宠物狗

C.在被探望的病人中,绝大多数喜欢并自己饲养宠物狗

D.志愿者带去探望病人的大多数狗都是性情比较温顺的

答案

参考答案:C

解析:解析:科学家的论点是:狗能帮助心脏病人降低焦虑情绪。这里的主要关系是狗和心脏病人,跟志愿者没有关系。而狗和病人之间的关系最有可能就是病人自己饲养狗,所以病人在见到狗的时候会减少焦虑,所以选C。不同的时间段、志愿者养狗以及狗都比较温顺都没有C选项更能削弱科学家的观点。
