Why should you use a shallow depth of field when photographing food?

Explanation:

A shallow DoF is a compositional choice that helps you viewer move to the most important part of the frame. This will tie into how many subjects you have as well. If you are shooting a large table scene, foodie gathering, it's likely that there are smaller stories within the overall image.

(a) i got it right on the test

i think these large heads represent their gods and i do think they were worshiped by the people. if there was only one head and no heads around it i think it would be monotheistic but if there are several heads close to each other it could be polytheistic.
