Answer:
A. Even though there were elections, the Soviet people had no real choice of leader.
Step-by-step explanation:
Document D is a cartoon that shows a Soviet citizen voting in an election. The only candidate on the ballot is Joseph Stalin, the leader of the Soviet Union. The cartoon suggests that the Soviet people had no real choice in their leaders, and that the elections were a sham.
The other answer choices are not supported by the information in Document D. Voting was not discouraged in the Soviet Union, and there is no evidence that the Soviets were afraid of voting booths exploding. The Soviet Union was not a great supporter of democracy, and Document D does not suggest otherwise.
