Question

what effect did austria-hungary declaring war on serbia have on alliances in europe?
○ russia ended its alliance with serbia.
○ great britain and france allied with russia.
○ germany ended its alliance with austria-hungary.
○ austria-hungary allied with france and great britain.

Explanation:

To solve this, we analyze each option based on WWI alliance dynamics:

• Option 1: Russia supported Serbia (Slavic ties), so it didn’t end the alliance. Eliminate.
• Option 2: After Austria - Hungary declared war on Serbia, Russia (allied with Serbia) prepared to intervene. Great Britain and France, part of the Triple Entente with Russia, allied with it. This matches historical events.
• Option 3: Germany was Austria - Hungary’s ally (Triple Alliance) and supported it. Eliminate.
• Option 4: Austria - Hungary was in the Triple Alliance with Germany, not allied with France/Great Britain (Triple Entente). Eliminate.

Answer:

B. Great Britain and France allied with Russia.
