LOST IN THE MOON

Read the following instructions.
You are a member of a space crew originally scheduled to rendezvous with a mothership on the lighted surface of the moon. Due to mechanical difficulties, however, your ship was forced to land at a spot some 200 miles from the rendezvous point. During the landing, much of the equipment aboard was damaged, and, since survival depends on reaching the mothership, the most critical items available must be chosen for the 200-mile trip. The 15 items left intact and undamaged after the landing include a box of matches, food concentrate, 50 feet of nylon rope, parachute silk, a portable heating unit, two .45-caliber pistols, one case of dehydrated Pet milk, two 100-lb. tanks of oxygen, a stellar map (of the moon's constellations), a life raft, a magnetic compass, five gallons of water, signal flares, a first-aid kit containing injection needles, and a solar-powered FM receiver-transmitter.
Your task is to rank order them in terms of their importance to your crew in reaching the rendezvous point. Using a scoring sheet like the one below of the print out version, place the number 1 by the most important item, the number 2 by the second most important, and so on, through number 15, the least important. You have 15 minutes to complete this phase of the exercise.(This first step can be completed individually by each participant before meeting in groups).
Do NOT discuss your answers with anyone before meeting in the group
