Which of the following can be used to investigate the reason the assassination of archiduke Franz Ferdinand sparked World War 1?
The role that East African soldiers played in the war.
Knowledge of the Schlieffen plan.
The collapse of the alliance system.
The national league of archiduke Franz Ferdinand's assassin.
Knowledge of the Schlieffen plan and the collapse of the alliance system can be used to investigate the reason the assassination of Archduke Franz Ferdinand sparked World War 1. The Schlieffen plan was a German military strategy that aimed to quickly defeat France in the west and then turn east to confront Russia, and its implementation played a significant role in the outbreak of the war. The collapse of the alliance system refers to the complex web of alliances between nations prior to the war, particularly the system of mutual defense agreements between various European powers, which were triggered by the assassination and led to the escalation of a local conflict into a global one. The role of East African soldiers and the national league of Archduke Franz Ferdinand's assassin are not directly relevant to the investigation of the specific cause and consequences of the assassination sparking World War 1.
