Question

social darwinists believed that
a religious and scientific worlds should be kept separate.
b powerful nations were meant to dominate weaker societies.
c the teaching of evolution theories in american public schools was unconstitutional.
d human beings had reached the point where competition among nations was no longer necessary.

Explanation:

Social Darwinists applied Darwin's theory of natural selection to human societies. They believed in the concept of "survival of the fittest" in social and political contexts. This led them to think that powerful nations (the "fittest" in their view) were destined to dominate weaker societies. Option A is more related to ideas of separating different spheres of knowledge (not Social - Darwinist core). Option C is about a legal - educational stance on evolution (not Social Darwinism). Option D contradicts the competitive nature that Social Darwinists emphasized.

Answer:

B. powerful nations were meant to dominate weaker societies.
