A recently published report indicates that the salaries of teachers continue to lag far behind other
college-educated professionals, because they make an average of nearly $8,000 a year less
at the
start of their careers and almost $24,000 less a year by the time they reach the age of 50.

(A) other college-educated professionals, because they make an average of nearly $8,000 a year
less at the start of their careers and almost $24,000 less
(B) other college-educated professionals, by an average of nearly $8,000 a year at the start of their
careers, to almost $24,000
216
(C) what other college-educated professionals are paid--making an average of nearly $8,000 a year
less at the start of their careers and almost $24,000 less
(D) those of other college-educated professionals--by an average of nearly $8,000 a year at the
start of their careers to almost $24,000 less
(E) those of other college-educated professionals--by an average of nearly $8,000 a year at the
start of their careers, and by almost $24,000

正确答案E中,and是什么意思。两个介词短语并列为什么and前面要加逗号??就两个东西并列,and前面加逗号,这是什么用法,不明白??

A and B 和 A, and B 都是可以接受的表达。
不过,更普遍的是:A, B, and C
