ap micro econ question (can someone explain this to me?)

Question

A second of which of the following is the most likely to provide more marginal utility than the first?

a) mailbox

b) t-shirt

c) shoe

d) car

e) refrigerator

Answer 1

Marginal utility is the additional satisfaction one receives from consuming another unit of the good. For instead, if I eat a second slice of pizza, the marginal utility would be how much extra happiness I receive from eating that second slice.

C appears the most logical answer here because a person needs two shoes to wear on their feet. One shoe wouldn't be that useful but two shoes is ideal.
