There is a widespread belief in the United States and Western Europe that young people have a smaller commitment to work and a career than their parents and grandparents and that the source of the change lies in the collapse of the "work ethic."
(A) a smaller commitment to work and a career than their parents and grandparents
(B) less of a commitment to work and a career than their parents and grandparents
(C) a smaller commitment to work and a career than that of their parents and grandparents
(D) less of a commitment to work and a career than their parents and grandparents had
(E) a lessening of the commitment to work and a career that their parents and grandparents had


我选的是A，我想问关于这类省略问题，怎么看出省不省会不会产生歧义啊，这道题我就没琢磨出歧义。。。

1）A,B中的歧义在于加粗部分不对等，young people have a smaller commitment to work and a career than their parents and grandparents

2）关于省略问题，推荐你看这个帖子

than前后比较的是句子的主语，这个句子是主谓宾结构，这种句子主语进行比较时，than的动词不能省略，否则就会有rylstar所说的比较歧义。
