The Welch-Rose report (1915) established graduate education in Public Health in U. S. Initially programs were only open to doctors and nurses. In what decade was graduate education in the U. S. opened up to those with college degrees in other areas?

Ithink b is the right answer

It's most likely choice a, it makes the most sense in my opinion.

This question is an opinionated one, and we don’t know anything about the module or anything, thus we can not answer it. but if you are having trouble on what it is asking basically it is just asking to (using your knowledge on the topic) say which topics you were most interested and which were the most challenging.hope this : p
