Scarcity in economics is to resource allocation as a traffic jam is to: ?

Scarcity in economics means that there are limited resources to meet unlimited wants and needs, which makes it necessary to allocate those resources in a way that best serves people. Similarly, a traffic jam occurs when there are more cars on the road than the road can handle, leading to a situation where vehicles cannot move freely. In both cases, the limited availability—whether it’s resources or road space—forces people to make choices about how to use what they have. For example, if a city has only one lane open during rush hour, drivers must decide whether to wait in line or take a longer route. Just like how resource allocation helps manage scarcity, finding alternative routes helps manage traffic jams.
