The statement that best investigates the relationship between social Darwinism and New Imperialism is:
Social Darwinism portrayed White Europeans as culturally superior to other races and was used to justify the colonization of other nations.
This statement accurately reflects how social Darwinism was employed during the New Imperialism era to rationalize the dominance and expansion of European powers over other cultures, often framing this dominance as a natural or inevitable outcome of perceived superiority.
