Task: Question Answering
Input (English): Passage: During the Second World War, by 1943, shortages in food and resources begin to affect all warring nations. In Nazi Germany, conditions harken back to the desperate years in the First World War and shortly after, when ordinary citizens were impoverished and forced to severely curtail their food intake. In Russia, families had to contend with the widespread destruction of their homes and farms. Bomb-scarred Great Britain survived by instituting strict rationing of food and conservation of strategic goods along with efforts to salvage metal in both domestic and industrial programs.
Even in affluent North America, the home front has been transformed by the exigencies of a "total war". While households may face the inevitable shortages, "tightening" the belt"has resulted in industrial production turned to arms manufacturing. Munitions factories are turning out the weapons of war for not only the United States and Canada, but also for faraway battlefields in China and Russia.
The massive amount of over production of goods has western leaders cautioning that the Great Depression was caused by greed and poor planning. In order to avoid repeating the economic crisis, careful planning has to take place. To ensure victory, an all inclusive program of sharing, conservation, salvage and rationing has been seen in every aspect of life. The scrap metal drives are only one of the examples of this new attitude.
With the forces of the New World about to collide with that of the Old World, the Axis powers build up their defences using forced labour. Across Northwest Europe, the "Maginot mentality" begins to take root as the Axis turns its occupied territory into Fortress Europe. The Allies realize that victory over the Axis powers will release the industrial might that was mobilized for war. 
Question: What countries did arms manufacturers in North America provide for?
Output (English): United States.
