According to the text, three women for every two men are enrolled in postsecondary education. This might lead to a reduction in the gender gap for all of the following reasons, EXCEPT that

A) sex discrimination still may persist in traditionally male-dominated professions.

B) graduation, not enrollment in college, will make the more appreciable difference.

C) women may choose majors of study that won't result in high-paying jobs.

D) a diminishing quantity supplied of college-educated males will shift the labor demand to the right.

E) increased competition from new females in the workforce will drive down the wages in male-dominated jobs.
