To encourage completion of this puzzle, I've added spoilers to indicate any correct or incorrect answers so far. Also, it's possible to work on Part 2 while Part 1 is incomplete or partly incorrect, and then go back and fill or correct answers to Part 1.
Write each answer as ONEWORD, without spaces, punctuation or abbreviating. Some questions may have more than one answer when taken alone, but only certain answers will work with respect to the whole puzzle.
