答案是A。我也选了。不过对A还是有疑问。我的理解是:the football players remain hostile after off-season. 也许能说明the football players are more hostile to start with than swimmers. 但是 前半句话,the football players become more hostile during the season. 难道不是暗算hostility 和contact games 还是有可能有联系的?
其实我也明白应该从这个方面找区别。想确认一下A潜在的意思。 football players become more hostile during the season and remain so off season. 这句话表明的是:football player 本身具有这种这种容易激动的素质?GMAT的表达总让我感到模模糊糊的,摸不找底。不知道为什么,我反而觉得LSAT的表达十分清晰。
