I want to know the answer to the following question:
In 2008-2009, how was BYU ranked nationally for the number of students who go on to earn PhDs?
All the background I'm provided with is that "A 2013 Quarterly Journal of Economics study of where the nation's top high school students choose to enroll ranked BYU No. 21 in its peer-reviewed study.". Is that enough to answer the question?
