Several studies have found that the coronary patients who exercise most actively have half or less than half the chance of dying of a heart attack as those who are sedentary. 我觉得A选项不正确 New York times 里面那句话是在普通英语语法的意义上是正确的,就像New York times 里面很有多宾语从句省略that一样。不过在GMAT语法更加严格,除非你能找到OG里面存在单用一个as——“......as....."的结构表示量的比较结构的句子,事实上你是找不到的,量的比较只有以下两大类种:第一类:the same as/as many as/as much as/X times as many as(确定比例) 第二类 more than/less than(不确定比例)
另外half or less than half比较wordy,如果是half or less还读得顺些,不过这里A不正确的主要原因就像解释里所说的,as单个不能进行比较,在GMAT的语法中!
