Replying to State Survey and Milk

So the other day in our American Studies class we took 30 minutes out of the class to take a state-wide multiple choice survey about our school enviorment, health, sex, and drugs. About 1/4th of the way through the test, after the section about how many times in the past weeks have you brought a weapon to school or how many times your get beaten by your girlfriend, there was a question asking on how much glasses of milk you drink in a day. I was confused on this random and totally out of place question because people seem to think it has to do with health and calcium intake and such but on the news just a few weeks before hand, there was a big story on how milk was shown to have NO relation to bone developement and growth. Can someone enlighten me on this matter?
