1)Attempting to improve relations with Asia

2)Refusing to join the League of Nations

3)Failing to sign international disarmament agreements

4)Lowering tariff rates

Answer 1

2) Refusing to join the League of Nations

Step-by-step explanation:

The best action that demonstrated the United States' effort to isolate itself from European conflicts after World War I is "Refusing to join the League of Nations."

This is evident in the fact that the United States Congress failed to pass the bill to join the League of Nations. This is based on the idea or some Isolationists' fear that it might make the United States drawn into International issues unnecessarily.
