Fifteen questions but only five answers? What kind of chicanery is this? Write the answer to the groups of three questions one after the other, 1-2-3. Even if you know #1 in the triplet, you don't get anything unless you know all three of them!
Remember, you're answering three questions simultaneously.
Your answers will look something like "Blue Washington Shintoism", with answers 1, 2, & 3 in order.
