Question: How did the Fourteen Points aim to prevent future wars through self-determination? The plan removed all borders between European countries completely. The plan allowed ethnic groups to form their own independent countries. The plan gave control of Europe to the strongest military powers. The plan forced all ethnic groups to live together in large empires.

1. **State the problem:** We need to understand how the Fourteen Points aimed to prevent future wars through the principle of self-determination. 2. **Explanation of self-determination:** Self-determination means that ethnic groups have the right to decide their own political status and form their own independent nations rather than being controlled by others. 3. **Analyzing the options:** - The plan did not remove all borders between European countries; borders were redrawn to respect ethnic groups. - The plan allowed ethnic groups to form their own independent countries, which aligns with self-determination. - The plan did not give control to the strongest military powers; it aimed to reduce conflict by respecting ethnic identities. - The plan did not force ethnic groups to live together in large empires; it aimed to avoid that to prevent conflict. 4. **Conclusion:** The correct understanding is that the Fourteen Points aimed to prevent future wars by allowing ethnic groups to form their own independent countries, respecting their right to self-determination. **Final answer:** The plan allowed ethnic groups to form their own independent countries.
