those are some odd questions. if it were a list of 100 question or so, it may make sense b/c you could build a real profile of a person and make some assumptions about the types of things they like to read. you'd be wrong sometimes, but would probably get a lot right. but with only 5 it seems like a lot of room for error in your profile.

here's guessing that the 5 magazines you pick entirely determines your articles. the other questions are likely used for some type of market research for the types of ads to run. I can't believe that your preference for those 5 questions would be very useful in article selection.
