If You Want to Predict the Grades for a Group

Multiple Choice

If you want to predict the grades for a group of first-year graduate students in physics, you can generally predict better from their GRE verbal scores than from their GRE quantitative scores. The main explanation for this observation is that

A) physics graduate students vary much in their verbal scores and only slightly in their quantitative scores.
B) the verbal part of the GRE has a higher reliability than the quantitative part does.
C) the first year of graduate school concentrates more on verbal materials than it does on quantitative materials, even in physics.
D) the mean verbal score is higher than the mean quantitative score, even for physics graduate students.
