The tourist trek from Lukla air base to the Mount Everest base camp only takes about 8 to 10 days and people usually hire porters to carry their camp food with them. As the previous answer stated, mountaineers who climb the mountain have lots of supplies including a range of food products that they also pay porters to carry or that they carry themselves along with camping and climbing gear and even oxygen tanks. You can't exert the amount of energy needed for strenuous high mountain climbing by existing on granola bars and nobody would want to try to exist on military MRE's.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
