Rationing is an attempt to limit shortages that naturally result from what?

Rationing is an attempt to limit shortages of a particular resource or goods by distributing it in a controlled way among the people who need it. Rationing is often implemented in times of war or other emergency situations, when resources are scarce and there is not enough to meet the demand of everyone who needs them. It can also be implemented in times of economic crisis, when prices for certain goods or resources rise dramatically, making them unaffordable for some people. Rationing can be used to ensure that everyone has access to a minimum amount of a particular resource, and to prevent hoarding or black market activity.
