route = ["LEFT", "UP", "RIGHT"]. Which option is ONE element of this list?
What is the index of the FIRST element in a Python list or an Arcade array?
route = ["LEFT", "UP", "RIGHT"]. What does route[1] read?
route = ["UP", "RIGHT", "DOWN", "LEFT"]. Which value does route[3] read?

answerIndex = 1. A reads route[answerIndex]. Which clue number should the game ask the player to recall?
Start with ["UP", "RIGHT", "DOWN"]. B sets route[1] = "LEFT". WITHOUT restarting, A reads route[1]. Which answer should now succeed?
Which A-button assignment still finds the correct target clue AFTER B changes the route?
How can you extend the existing three-clue route to FOUR clues?
You want A to ask for clue 3 and B to change THAT SAME clue. Which pair of edits is correct?
Start with route = ["UP", "RIGHT", "DOWN"]. Run route[0] = route[2], then route[2] = route[0]. What is the result?
