The topic I was studying was the 3 economic systems -capitalism, socialism, and communism. I have some questions regarding them please answer them in detail.

1)How do all three economic systems determine and ensure that goods and services are distributed? Does the government play much of a role, or none at all?

2)What are some of the common criticisms you think can be heard (from not only economists but politicians) that each economic systems face? are these criticisms are valid?

3) is it a strong case for governments to adopt a certain type of economic system over the other?Please provide examples so I can understand better.
