After the practice test

Use your Columbian Exchange misses to sharpen causation

If you missed disease questions, separate immediate biological vulnerability from the additional effects of conquest, forced labor, displacement, famine, and repeated epidemics. Strong answers usually explain interaction rather than searching for one cause that does everything.

For crop and livestock questions, ask where the organism originated, why it could thrive in the new environment, and what changed because people adopted it. A potato in Europe, cassava in Africa, and horses in North America belong to the same exchange but produced different social consequences.

When a stimulus shows a commodity or organism far from its place of origin, do not overclaim. Movement proves connection. Political control, cultural replacement, or demographic impact require additional evidence.

Your next targeted practice

Once you can explain your missed answers without reopening the choices, move to the maritime empires assessment. Use the next test to transfer the reasoning to a related historical problem rather than memorizing this page.
