You and three companions have secured a General Store that carries foodstuff, basic hardware tools, and basic camping supplies but can only take roughly four backpacks worth of things with you back to base.
Lots of non-perishable food (canned vegetables, jerky) and the gear needed to fashion a rain catcher.(tarp, wiring/rope)-non-perishable food is always the best option for stocking your base, while fatty high carbohydrate foods are better for the field. eat what you can to keep your energy up while traveling, but dont bring a lot it with you. bottled water is rarely a good idea unless youre severely short or in drought conditions. answer a is the best option, even though b, c and d might get you by, it may come back to bite you or your companions in the backside in the long run. answer e is the worst for several reasons: the fact that other survivors will be coming to collect supplies and not all of them will be willing to share could get you shot. most markets are difficult to barricade, and unless you remove and burn all perishable food from the site, it could pose a health hazard to you and your companions.
