题目内容
It is widely assumed that people need to engage in intellectual activities such as solving crossword puzzles or mathematics problems in order to maintain mental sharpness as they age. In fact, however, simply talking to other people--that is, participating in social interaction, which engages many mental and perceptual skills--suffices. Evidence to this effect comes from a study showing that the more social contact people report, the better their mental skills.

Which of the following, if true, most seriously weakens the force of the evidence cited?
  • AAs people grow older, they are often advised to keep exercising their physical and mental capacities in order to maintain or improve them. 分析该选项
  • BMany medical conditions and treatments that adversely affect a person`s mental sharpness also tend to increase that person`s social isolation. 分析该选项
  • CMany people are proficient both in social interactions and in solving mathematical problems. 分析该选项
  • DThe study did not itself collect data but analyzed data bearing on the issue from prior studies. 分析该选项
  • EThe tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to conversation. 分析该选项
