Windows 10 is the latest iteration of Microsoft's operating system. Desktops with Win 10 and previous versions are what most people typically use, so you'll be assured of the best compatibility and widest selection of third-party software. This also applies to browser plugins, since some only work with Windows. Apple's OS X is currently up to version 10.11 (El Capitan).
World War II (WWII), also called the Second World War, was a global war. It took place from 1939â1945. Most of the world's countries, including all the great powers, fought as part of two military alliances: the Allies and the Axis. The war was fought as a total war, meaning all resources a country had were used in the war, even those that didn't belong to the army, such as factories.
Germany invaded Poland in 1939, and the world  almost every country except the U.S.  was at war. Agricultural exports dropped as German submarines, known as U-boats, were sinking U.S. ships to England and Europe.Farming exports fell 30 to 40 percent below the average of the ten depression years that preceded the war.hen the U.S. officially entered the war, the need for food increased even more. Soldiers could fight only as long as they had food to fuel their bodies. So, farmers were exhorted to produce even more.
