Question

1. What factors contributed to the outbreak of World War I?

2. Why did the assassination of Archduke Francis Ferdinand spark war rather than diplomacy?

Answer 1

Before World War 1 countries were forming alliances. Britain
 and France were allied with Serbia and German and Russia were allied with Austria-Hungary. When Archduke Ferdinand was assasinated all these countries were brought into a "local" war between Serbia and Austria-Hungary. Hope this helps!
