Question

scarcity
stems from the incompatibility between limited resources and unlimited wants
can be overcome by discovering new resources.
can be eliminated by rationing products.
is a bigger problem in market economies than in socialist economies.

Explanation:

Scarcity is a fundamental concept in economics. It arises because resources (such as land, labor, capital) are limited, while human wants and needs are unlimited. Discovering new resources may alleviate scarcity for a time but doesn't eliminate it as wants remain infinite. Rationing products is a way to distribute scarce resources but doesn't solve the root cause of scarcity (the mismatch between limited resources and unlimited wants). Scarcity exists in all economic systems (market, socialist, etc.) as the basic problem of limited resources and unlimited wants is universal.

Answer:

"stems from the incompatibility between limited resources and unlimited wants"
