Question

how did britain experiment with alternatives to capitalism? by temporarily adopting a welfare state by committing to a full barter system by reverting to colonial mercantilism

Explanation:

After World War II, Britain adopted a welfare - state model. This involved the government taking on a larger role in providing social services such as healthcare (the creation of the National Health Service), education, and social security. This was a departure from pure capitalism as the state was more involved in redistributing resources and ensuring a basic standard of living for its citizens. A barter system is an archaic form of trade and was not adopted. Mercantilism was an economic system of the past (16th - 18th centuries) focused on trade surpluses and colonial expansion, which was not relevant in the post - WWII context of looking for alternatives to capitalism.

Answer:

by temporarily adopting a welfare state
