5. Identify two things that could have prevented a world war, based on what happened after the assassination of Archduke Franz Ferdinand.

The first one would be that Serbia totally accepted the Austro-Hungarian ultimatum to them after the assassination and the other would be if Russia and other great powers didn't support Serbia in the dispute.

Explanation:

Ferdinand was killed on June 28th 1914 by a Serb called Gavrilo Princip. Austria-Hungary blamed Serbia and asked Serbian authorities to allow them to research what happened on the soil of Serbia.

After Austria-Hungary declared war on Serbia, Russia and other forces started to enter the war.
