Answer from cs61c-ev (Roland Carlos 16583196) for Question 1
Spatial locality: If you're cooking some sort of themed meal (all fruits for example), when you find one fruit at the supermarket, you'll probably find other fruits that you may need nearby.

Temporal locality: You plan to make several different dishes, but you're focusing on just one recipe right now. So you would most likely refer to the current recipe that you're working on now sooner than you would another different recipe.
