B 选项是不是说反了。 第二段实验反驳了theoretical economics的观点,theoretical economics的观点是 selfish B选项 use a study to challenge the argument that the economic behavior of human beings may be motiviated by factors other than selfishness 注意是 other than, B选项的意思是用一个 study 来 challenge 一个观点, 这个 观点 是 除了 selfish 意外的因素激发人类行为 也就是 not support the argument that the factor does not include selfishness 双重否定= 支持 selfishness -- by 会员 呓语 (2012/5/4 21:58:30)
