Answer:
the half sandwich
Step-by-step explanation:
actually, Emmanuel should eat just the ham and not the bread. meat is a protein, proteins take longer to digest and are best at fueling your brain. the bread is a carbohydrate, which will break down into sugars. sugars on an empty stomach flood your cells and can cause sleepiness. Cheese would be even better. black coffee is good, too. black, no cream or sugar.
