Industry is usually one of the major deciding factors in a victorious outcome in war. true false

That seems more of a question for discussion than a true-false assertion.  "Usually" and "one of the major factors" already hedge the statement in such a way that calling it clearly true or false would be problematic.  And the history of warfare can show examples from either side of the equation.  In the US Civil War, the North's industrial advantage was a significant factor in its favor. On the other hand, in the United States pursuance of war in Vietnam, the enormous industrial strength of weaponry that the US could bring to the war could not defeat the determination and resilience of their highly motivated opponents in Vietnam.  

If "usually" and "one of" the factors are in there as a hedge, I suppose you could assert the statement as true, but again, it seems to be a question more fitting for discussion and defense using historical examples.

The correct answer is A) ending the Great Depression.

Franklin Roosevelt's New Deal was most notable for ending the Great Depression.

Although he received critics from his political rivals, the action that helped to bring the United States out of the Great Depression in the late 1930s was that Franklin Roosevelt started the New Deal.

When Franklin D. Roosevelt became the United States President in 1933, one of his priorities was to help the poor citizens who were suffering the harsh economic conditions of the Great Depression that started on October 29, 1929, after the US stock market crash. Roosevelt created the "New Deal," which was a series of economic programs aimed to help the ones in need. Some of those programs were the Tennesse Valley Authority, the Civilian Conservation Corps, and the Civil Work Administration.
