Check every lap!

Rocket puts a check inside a loop.

Now Nova asks the question every lap.

On some laps the answer is false.

Then on one lap, it turns true!

Raven thinks about the auto-pilot drop.

The drop also comes on one lap, every time.

WARM-UP: IS IT EXACTLY?
  • Peek in the box.
  • Tap true or false.
