Explanation:

To answer this, we analyze the alliance system before WWI. The Triple Entente (Britain, France, Russia) and Triple Alliance (Germany, Austria - Hungary, Italy) were key. When Austria - Hungary declared war on Serbia (backed by Russia) in 1914, Russia mobilized. Germany, allied with Austria - Hungary, declared war on Russia. Then France, allied with Russia, was drawn in. Germany's invasion of Belgium (to attack France) brought Britain (allied with Belgium and France) into the war. This shows how each alliance's enemy declaration created a chain reaction.

Answer:

Support with Evidence:

The Triple Alliance (Germany, Austria - Hungary, Italy) and Triple Entente (Britain, France, Russia) were pre - war alliances. When Austria - Hungary declared war on Serbia (supported by Russia) in 1914, Russia began to mobilize. Germany, as an ally of Austria - Hungary, then declared war on Russia. France, allied with Russia, was subsequently drawn into the conflict. Germany's invasion of Belgium (a neutral country with ties to Britain) led Britain, part of the Triple Entente, to declare war on Germany.

Provide Reasoning:

These examples support the claim because each country's alliance obligations forced them to act against the enemies of their allies. Austria - Hungary's war on Serbia (a Russian - backed state) triggered Russia's involvement. Germany's alliance with Austria - Hungary meant it had to confront Russia, and its actions against Belgium (to attack France) brought in Britain and France. This sequential declaration of war against the enemies of one's allies is the chain reaction caused by the alliance system, leading to the widespread conflict of World War I.
