问题 单项选择题

研究人员对716名平均年龄为82岁的志愿者进行研究,要求志愿者佩戴一个小型仪器以监控日常活动,还对他们进行认知水平测试,评估记忆力和思维能力。大约3年后,研究人员发现,日常活动最少的志愿者罹患痴呆症的几率是日常活动最多的志愿者的两倍多。因此,洗衣、做饭、打扫卫生等家务活有助于降低老年人包括80岁以上人群罹患痴呆症的几率。
以下哪项如果为真,最不能支持上述结论

A.研究结果显示,所有身体活动,包括健身、做饭、洗衣、洗碗、打扫卫生等活动都与老年人患痴呆症风险降低存在关联
B.保持正常体重,戒烟,采用地中海式饮食,多吃富含抗氧化成分的食物和鱼也有助于降低老年人罹患痴呆症的几率
C.借助小型仪器监控身体活动比通过自我报告式的调查问卷更可靠
D.研究显示,那些无法参与正规锻炼的高龄人群通过家务活动提高了自己的记忆能力

答案

参考答案:B

解析: 题干由研究得出“洗衣、做饭、打扫卫生等家务活有助于降低老年人包括80岁以上人群罹患痴呆症的几率”的结论。A项直接加强了结论;B项与题干结论无关;C项说明研究的科学性,加强了论据;D项提出新的论据,从而加强了结论。故答案选B。
