1. When is a good or service scarce?
a. it is rare and hard to come by.
b. there is not enough of it available for
everybody who wants it for free.
c. there is plenty available for everyone who
wants it.
d. there is a shortage.
B. Scarcity means that there is not enough of

gets and who does not get.

the choice made is the one that they believe
will increase their total welfare.
