Emek and Luna explored a cave and came to two tunnels. Lanterns marked the safe path. The pattern was 1 red lantern, 2 blue lanterns, 1 red lantern, then 2 blue lanterns. At the tunnels, one showed a red lantern next, while the other showed a blue lantern. Luna checked where the pattern ended. Emek knew the next lantern should be red. They chose the tunnel with the red lantern and found the way out.
