问题 Passage Three [br] What does the word "non-demented" in Para.2 probably mean?
选项
答案 Mentally clear．
解析 根据原文第二段第二句“...with 1,077 non-demented and otherwise healthy people aged between 60 and 90.”可知，调查研究的对象是1077名60岁到90岁之间的non-demented和healthy的人，其中的and otherwise表明这两个词在意思上是并列、递进的关系；再根据第三段前两句可知，在研究的前十年里，志愿者中有43人患上了阿尔茨海默病，后面又将这些患阿尔茨海默病的病人与未患病者进行比较。综上所述，可以推出“Mentally clear.”为正确答案。
