which event correctly completes this graphic organizer?
launch of the manhattan project to develop the atomic bomb
nazi-soviet non-aggression pact to keep germany and the soviet union from attacking each other
formation of the league of nations to help prevent wars

Explanation:

The graphic organizer starts with Einstein warning Roosevelt about Germany's potential to build a powerful bomb (atomic bomb, related to uranium), then Roosevelt sets up a committee to study uranium in 1939. The next logical step is the launch of the Manhattan Project, which was the U.S. effort to develop the atomic bomb. The Nazi - Soviet Non - Aggression Pact is about Germany and the USSR not attacking each other, unrelated to uranium study for bomb development. The League of Nations was formed after WWI, much earlier and not related to this uranium - bomb development sequence.

Answer:

A. Launch of the Manhattan Project to develop the Atomic Bomb
