Final answer:
In a free market system, 'government' is typically the most limited in scope, as the system is characterized by minimal government intervention, with the government acting mostly as a regulator, protector, provider, consumer, and promoter.
Step-by-step explanation:
The question asks which is assumed to be most limited in scope under a market system. Under a capitalism or free market system, there are certain characteristics that define its operation, including economic freedom, competition, and voluntary exchange. Among the options provided, the most limited in scope is generally considered to be government because a free market operates with minimal government intervention. The government's role is primarily as a regulator to ensure competition, a protector to prevent abuse, a provider of services, a consumer of goods, and a promoter of national goals. However, this intervention is limited to maintain the capitalist nature of the economy.
