标题: 一道GRE&lsat逻辑题求解释 [打印本页] 作者: witty1 时间: 2011-4-14 21:41 标题: 一道GRE&lsat逻辑题求解释 A small dose of a widely used tranquilizer allows people to lie during lie detector tests without being discovered. The stress responses that lie detector tests measure can be inhibited by the drug without noticeable side effects. One of the implications of this fact is that the drug can also be effective in reducing stress in everyday situations.
An assumption of the passage is that
A tranquilizers are always an effective treatment for stress B the inhibition of stress responses increases subjective stress C stress as measured by a lie detector is similar to every-day stress D persons who lie during a lie detector test always display signs of stress E it is not desirable to reduce stress in everyday situations

求解释，有木有作者: wlf1987 时间: 2011-4-14 22:55
C是正确答案？取非，如果不是类似的，那就不好直接用了。 D这个不是假设，取非啊，如果并不总是表现压力，也不影响文章。文章成立并没要一定表现压力作者: sdcar2010 时间: 2011-4-15 11:25
This is a sufficient assumption.
Premise: Drug can inhibit stress response measured by a lie detector. D can inhibit A.
Conclusion: Drug can mitigate every-day stress. D can inhibit B.
Well, if A = B, and D can inhibit A, of couse D can inhibit B.
