Government Directly Supplies Public Goods

Steps:

• Define direct provision as government delivering goods/services itself, like infrastructure or utilities.
• Review options for actions where government acts as producer/provider, not just regulator or financier.
• Eliminate indirect interventions like payments, subsidies, or taxes.
• Identify the option involving government's own operational delivery.

Why A is correct:

• Road maintenance is a public good directly provided by government agencies, fulfilling infrastructure services as per public economics definitions.

Why the others are wrong:

• B: Transfer payments redistribute income, not provide goods/services.
• C: Subsidies offer financial incentives to private firms, enabling indirect market provision.
• D: Taxes enforce environmental regulation without supplying goods/services.

Final answer: A
