They need to each bring a hammock.
one being a solid fabric type, waterproof sprayed at home, so it can become their tent, liner for their stone-boiling pit and water storage liner/basket. The other hammock should be a cotton rope type, for a cordage source. Unravel it, unravel the rope and the strands and you can make 1200 sq ft of 2" mesh netting. used as a seine and a couple of baited weirs, it will feed you any place with a body of water and fish. Netting can also be wrapped around stick boxgrames, and used to catch birds, crabs, rabbits, crayfish, even snakes.. cordage can be wrapped around a stick (longways) and then sewn, forming the sole of a sandal, which you badly need on this challenge. out of the items offered you by the producers, take the machete. In 2-3 hours, you can make the big pump drill needed to always, easily get friction fire.
