The correct answer is: A. Public transport system
A free trade economy is an economic system in which goods and services are traded freely between countries without government intervention. This means that businesses are free to buy and sell goods and services from other countries without having to pay tariffs or other taxes.
Public transport systems are not typically provided by free trade economies. This is because public transport systems are often seen as a public good, which means that they are beneficial to society as a whole, even if they are not profitable. In a free trade economy, businesses are only motivated to provide goods and services that are profitable. Therefore, public transport systems are often left to be provided by the government.
Pensions, national security, and education are all goods and services that are typically provided by governments. This is because these goods and services are seen as essential to the well-being of society. Governments have a responsibility to provide these goods and services to their citizens, even if they are not profitable.
In conclusion, the correct answer is: A. Public transport system. Public transport systems are not typically provided by free trade economies because they are seen as a public good, which means that they are beneficial to society as a whole, even if they are not profitable.
