The need to construct a scale of preference is necessitated by?

The need to construct a scale of preference is necessitated by scarcity and the need for choice. Scarcity means that there are limited resources to fulfill unlimited wants and needs. Therefore, individuals must choose which wants and needs to satisfy and in what order of importance. This is where the scale of preference comes in, as it is a tool that helps individuals to rank their wants and needs in order of priority and to allocate their scarce resources towards fulfilling the most important ones first. Without a scale of preference, individuals may end up making poor choices that do not align with their priorities and lead to unsatisfactory outcomes. So, the option that best represents the need to construct a scale of preference is "scarcity and the need for choice."
