Answer to Question 1

B

Answer to Question 2

Scarcity means that there are not enough goods and services to satisfy unlimited human wants. When more people want something than can have it, some way must be found to determine who gets the available units. This process is rationing. Rationing can be done by using prices to ration a good to those most willing and able to pay the highest price. First-come-first-served rations by queues, lotteries ration on the basis of chance, discrimination rations on the basis of racial, ethnic, or gender preferences, and so on.
