Question

according to karl marx, the economic ideas behind socialism would lead to a
communist revolution.
socialist revolution.
capitalist revolution.
utopian revolution.

Explanation:

Karl Marx proposed that the contradictions within capitalism (such as class struggle between bourgeoisie and proletariat) would be addressed by socialist economic ideas. These ideas, according to Marx, would ultimately lead to a communist revolution where the means of production are commonly owned and class distinctions disappear. Socialist revolution is a stage towards communism in Marxist theory, but the end - goal based on the economic ideas (which critique capitalism and propose a new economic order leading to classless society) is a communist revolution. Capitalist revolution is against Marx's critique of capitalism. Utopian revolution refers to idealistic (not based on materialist analysis like Marx's) revolutionary ideas.

Answer:

communist revolution.
