Question

Which country joined the Allies after Hitler's army attacked it in June of 1941? A. the United States B. the Soviet Union C. China D. Canada

Answer 1

We can step through this one too!

Not (A), at least not yet. The US supported its allies in Europe, but it didn't formally join the war until December. (C) isn't technically right, either, because China had already been fighting a war of its own against the Japanese in the East. And not (D). Canada had already declared war on Germany after they attacked Poland.

So the right answer has to be (B) the Soviet Union. It was in June, 1941, that Germany launched its massive surprise invasion of the Soviet Union also making it the largest land invasion ever in history.
