Immediately after the Brook Situation, the same group was taken to a wall and asked to imagine this wall was a barrier they could not go around or look around. Furthermore, behind this wall was a canyon and on the other side was another wall. The situation is that they were trying to escape from Japanese soldiers and must figure out how to get the entire group to the other side, carrying their bazooka (a log). Anything (or one) that fell between the walls was lost. Timing began immediately. Solving the problem required getting quickly to the top to assess the situation and determining a way to measure the gap with available tools in order to decide what could be used to cross it. The same variables were observed as in the Brook Situation.
Usually the leader was the person who got to the top of the wall first to study the situation-- although he could not maintain his authority if that was all he offered the group.
This task required managing human resources. For example, leaving a large or awkward person as the last to climb up on the wall would result in problems. Having a confident member cross first would help the more timid. At the end of these two tasks the group members generally displayed greater sociability toward each other.
