答案是B.我知道其他都有错误，但是B选择中最后一部分：[size=13.600000381469727px]attitudes toward children and families and...中间有两个and，并且有没comma分隔，这不会出现歧义吗？我记得之前GMAT的题目，一般遇到这样两个and并列的，这个选项都是错的。
可以不用逗号分隔连用两个and? 求NN解惑

这两个and的层级是不同的，这种情况下用了逗号反而不好。

后半句的主干是：

恩，后面不是独立的SVO..thx！

后半句的主干是：
..helped shape opinion in such areas as attitudes and the relative merits. 这里显然是不用加任何逗号的。

然后仔细说了了一下attitudes和merits的内容：
1. attitudes toward children and families
2. the relative merits of competition and cooperation

所以在任何地方加逗号都是没有特别必要的。and的层级不同。这和SVO, and SVO里面的and作用是不一样的。
