Answer:
They are forces of production and social relations of production.
Explanation:
In Marxism and historical materialism the forces of production are a central idea. In the own critique of political economy by Karl Marx and Frederick Engels, it refers to the combination of the means of labor with human labor power.
forces of production is a term used in political economy that refers to the physical means and production techniques to which laborers add value and transform capital into saleable products.
By " relations of production," Marx and Engels meant the total sum of social relationships that people have to enter to survive, produce, and reproduce their means of living...relations can be social ties, economic relationships, or technological relationships.
