Explanation:

First Question:

The assassination of Archduke Franz Ferdinand in 1914 triggered a series of diplomatic crises that led to the start of World War I. The German invasion of Belgium was part of the war's early actions, Russian withdrawal and U.S. entry happened later.

Germanic (related to German - led interests) and Slavic (with Russian - led Slavic interests) had competing interests in Central and Eastern Europe. The Ottoman Empire was more involved in the Middle East and other regions, and the Russian Empire's interests were more aligned with Slavic groups.

Pre - existing defense pacts (like the Triple Entente and Triple Alliance) drew Western European countries (e.g., France, UK) into the conflict when the war started in Central Europe. They did not prevent the war from spreading, nor did they favor Central Powers or weaken Allied forces in this context.

Answer:

b. Assassination of Archduke Franz Ferdinand
