According to the ideas of Karl Marx, what is the primary cause of social change?

While economic progress is a factor in societal development, it is not the primary cause of social change in Marx's framework. Economic advancements can occur without significant social alterations unless paired with class struggles that challenge existing power structures. Therefore, this option does not capture the essence of Marx's theory.

Although industrial progress contributes to changes in society, it is not the fundamental cause of social change according to Marx. Industrialization may exacerbate class tensions and conflicts but is seen as a backdrop rather than the driving force of social transformation. Thus, it fails to address the root causes highlighted by Marx.

Marx viewed religion as a tool used by ruling classes to maintain control over the oppressed, rather than as a primary driver of social change. While religious conflicts can influence society, they are secondary to the economic and class dynamics that Marx argues are the true engines of historical progress.
