Answer from cs61c-aq (Anjali Koppal 16454392) for Question 1
In a grocery store, the managers put a lot of thought into deciding which item should be placed next to which. this is because of our tendency to akin to spatial locality. we are more likely to pick up something new if it is near something we already wanted, rather than go search for it in another place. 

temporal locality might be applied by driving. people quickly get adjusted to certain route between two places and tend to take the same route even if there might be another but less familiar way to get to their destination.
