求讲解,剑桥雅思3,test3,阅读第三篇的第30题,
serotonin is an essential cause of human aggression是对,错还是没告
文章最后一段倒数第16行写道:high levels of sertonin in certain areas of the nervous system make people more active and reactive and,possibly,more aggresive.
写的很明显了啊,会引起aggression,可是为什么选F呢?

possibly 是关键 没有说一定 只是可能 与题意不符的
或者看前面那个high level 而不是所有的sertonin都有这个作用
