The third person is he/she/it/they.

Answer: 3. The German people were unaware that their army was beaten and that its leaders had demanded an end to the war.
Explanation:
General Pershing did not believe an armistice was the best way to end the war. He wanted Germany to surrender unconditionally when Allied armies had gone into Germany and taken over it militarily as well as disbanded its army and reduced its economy.
This way he argued, the German people would know that they were beaten an did not choose surrender but rather were forced into it. He believed this was how such a war should have ended.
