Final answer:
Because the government owns the factors of production in public lands, postal service, and some water resources, Great Britain is considered a public enterprise economy.
Step-by-step explanation:
Because the government owns the factors of production in public lands, postal service, and some water resources, Great Britain is considered a public enterprise economy. This means that while it typically allows for the ownership of private property, the government retains substantial control over crucial resources and industries, often to address issues related to public and common goods, such as forests, water, and fisheries.
The presence of government ownership in these areas is essential to prevent situations like the tragedy of the commons, which can arise from unregulated exploitation of resources.
