Explanation:
Spain managed to conquer lot of territory in the New World without any particular problem, but a problem arose later as Spain didn't had enough people to settle all the areas that it had conquered. One of those areas was Florida. The Spanish lacked people to make large and strong settlements in Florida, and on top of it, they were in constant conflict with the neighboring Georgia, thus Florida became a burden. In order to calm things down, the Spanish and the United States set on a negotiating table. Through negotiations, Spain gave Florida to the United States, while the United States backed off from the troublesome boundary along the Sabine River in Spanish Texas.

Answer:
Explanation:
Hitler appointed Hjalmar Schacht as President of the Reichsbank in 1933 and Minister of Economics in 1934. He created a bunch of public works programs which were supported by deficit spending. But then Hjalmar Schacht created a scheme for deficit financing, so capital projects were paid for with the issuance of promissory notes called "Mefo bills" and because "Mefo bills" wasn't Germany's official currency so it didn't show on their federal budget. But then that fell through, and the government basically made banks buy federal bonds so the German government could pay back the "Mefo bills". But  Schacht achieved a rapid decline in the unemployment rate, the largest of any country during the Great Depression because of his public works and by 1938, unemployment was basically non-extinct.
