Which Allied invasion helped ease the German advance into the Soviet Union?

Sicily Invasion
Normandy Invasion
Invasion of Berlin
Invasion of Paris

D?

The correct answer is the Sicily Invasion.

The Allied invasion that helped ease the German advance into the Soviet Union was the Sicily Invasion.

To find the answer, you can first rule out options like Invasion of Berlin and Invasion of Paris, as these invasions occurred later in the war and did not directly contribute to countering the German advance into the Soviet Union.

Next, you can focus on the Normandy Invasion and the Sicily Invasion. The Normandy Invasion, also known as D-Day, took place in June 1944 and aimed to liberate France from German occupation. While the Normandy Invasion played a crucial role in defeating Germany in Western Europe, it did not directly affect the German advance into the Soviet Union.

Therefore, the correct answer is the Sicily Invasion. This invasion, also known as Operation Husky, took place in July 1943 and involved the landing of Allied forces in Sicily, which eventually led to the ousting of Axis forces from the island. By diverting German resources and attention away from the Eastern Front, the Sicily Invasion helped ease the German advance into the Soviet Union, enabling the Soviets to gain a strategic advantage.
