试题详情
题目：
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?
Which of the following, if true, most seriously weakens the force of the evidence cited?
选项:
A、As people grow older, they are often advised to keep exercising their physical and mental capacities in order to maintain or improve them.
B、Many medical conditions and treatments that adversely affect a person’s mental sharpness also tend to increase that person’s social isolation.
C、Many people are proficient both in social interactions and in solving mathematical problems.
D、The study did not itself collect data but analyzed data bearing on the issue from prior studies.
E、The tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to conversation.
答案:
B
提问：
Tina老师好，这道题我错选C，而且不理解B为什么对。我的做题思路是：社交多的人——脑力好，削弱这点，C有的人既数学能力强，又社交能力强，本来应该二者取一，现在二者都有就反驳了社交导致脑力好的说法。我觉得挺对，不知道为什么，B选项：一些影响脑力的治疗也会影响社交，能反驳。这题如果用逻辑链应该怎么想？
谢谢Tina老师
