8. What things did the Runners do while inside the Maze? Why?

The two boys enter Section 8. Thomas follows Minho, observing his skills and tactics as a Runner and map maker. Minho makes notes here and there, citing what has changed from the day before. As he turns a corner he takes out a knife and cuts a piece of ivy off the wall, throwing it on the ground to mark his path like Hansel and Gretel. He asks Thomas to take over for a while so he can learn the skill.
