Lost at Sea Activity

In this activity, we had a list of fifteen items that we could use to survive and get rescued. We had a raft, and matches and had to use these items to get rescued first, then survive.
my items were:
1. a 25 liter container of water
2. a case of army rations
3. a fishing kit
4. a small transistor radio
5. maps of the pacific ocean
6. 15ft nylon rope
7. 20 square feet of opaque plastic sheeting
8. a can of shark repellent
9. 2 boxes of chocolate bars
10. a sextant
11. a quantity of mosquito netting
12. one bottle of 160 per cent proof rum
13. a 10 liter can of oil/petrol mixture
14. a floating seat cushion
15. a shaving mirror
I picked the water and the case of army rations as my first two picks because you need both water and food in order to survive. My team and I took votes on what we thought our items should be ranked, one item that was similarly close to mine was the water which was exactly the same. An item that was ranked differently was the can of oil/ petrol i ranked it thirteen, my group ranked it number four. My answers and the expert answers were way different, i thought surviving was the key thing, but getting rescued turned out to be more important. I would trust the expert opion more because they are an expert and we are not.
