Question

what is missing from the diagram showing the relationship among human migration, ideas, and customs?
new ideas and beliefs emerge from the different groups.
the more powerful group puts their ideas into practice.
groups agree to live together in a separation of ideas and beliefs.
new customs and beliefs are adopted.

Explanation:

When human migration occurs, different groups with their own ideas and customs interact. The key outcome of such interaction in terms of the relationship between migration, ideas, and customs is the adoption of new customs and beliefs. The first option talks about new ideas emerging, but the core of the relationship here is about adoption due to interaction. The second option is about a powerful group imposing ideas, which is not the typical or main outcome of general human migration - idea - custom relationships. The third option about separation of ideas and beliefs goes against the idea of interaction leading to a relationship among them. So the correct one is the option about adopting new customs and beliefs.

Answer:

D. New customs and beliefs are adopted.
