Hypotheses

 * 1) Quiz questions about radiation astronomy may be made too difficult.
 * 2) Quiz questions could start out as easy association and work up to more difficult.
 * 3) In 2015 two quizzes made the top 1000: Planets/Quiz and Classical planets/Quiz, as such more quizzes may make this list.
 * 4) Intergalactic medium was averaging 6 hits per day, but after the move to the subpage its down to 1 per day, which suggests that subpaging reduces reader interest or access.
