Generate a Themed Trivia Round From a Topic You Choose

Quiz night is tomorrow and the round on your assigned topic does not exist yet. This generates ten questions running from easy to hard, mixes in a picture-round style question described in words, and hands you an answer key with sources, so a dispute at the table can actually be settled.
