Question

why did the soviet union join the allies?
○ stalin was afraid of hitler.
○ hitler had broken a pact and attacked.
○ hitler was becoming too powerful in eastern europe.
○ stalin wished to take control of territories captured by germany.

Explanation:

To determine why the Soviet Union joined the Allies, we analyze each option:

• Option "Stalin was afraid of Hitler" is incorrect. The Soviet Union joined because of direct aggression, not fear.
• Option "Hitler had broken a pact and attacked" is correct. Hitler broke the Nazi - Soviet Non - Aggression Pact (Molotov - Ribbentrop Pact) and launched Operation Barbarossa, attacking the Soviet Union in 1941. This forced the Soviet Union to join the Allies to fight against the Axis powers.
• Option "Hitler was becoming too powerful in Eastern Europe" is not the direct reason for the Soviet Union's entry into the Allies. The direct trigger was the German attack on the Soviet Union.
• Option "Stalin wished to take control of territories captured by Germany" is incorrect. The Soviet Union's entry was a response to German aggression, not an attempt to seize German - captured territories.

Answer:

B. Hitler had broken a pact and attacked.
