    C

    many college graduates might never find jobs for which they are trained

    D

    正确答案: D
    解析:
    首段第四句指出“The result is that the graduates cannot enter the professions for which they are trained and must take temporary jobs, which do not require a college degree”,大学毕业生找不到专业对口的工作,只能做一些临时性的工作,而这些工作根本用不着大学学历。由此可知,如果市场不能为大学毕业生提供专业对口的工作,那么高端人才只能去做临时工,这会成为惯例,因此选C“许多大学毕业生也许永远找不到专业对口的工作”。
