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


正确答案D，有三个问题求教
1.less对应不可数，为什么of后面是a commiment
2.比较结构的助动词补出为什么补出had而不补出have
3.个人认为A和C的比较对象也是对等的啊 that指代commitment  前后比较的是年轻人的commitment和成年人的commitment


求大牛解答，不胜感谢！！！

这题的主干是比较句子。 young people have .... less  than parents had.   
1）额，这里我觉得less是做名词用的。。。。  
2）时态变了必须补出来。 这是比较的过去与现在。 所以要用HAD。
3） "that of their parents" is a possessive, and there's no corresponding possessive on the left. 所以that无指代。错
