B. Begin their own revolutions.
The 1848 Springtime of peoples were a series of republican revolts opposite to the European monarchies. This revolutionary movement started in Italy with a local revolution in Sicily in January 1848. France followed and soon the movement had extended throughout Germany, Italy, and the Austrian Empire. All these revolutions failed and were severely repressed.
American forces drove German troops out of Egypt. Operation Torch became a victory for the Allies.
Sources such as diaries though not very reliable can be used if there are a large amount of them showing the same date and event. Historical books written about the event especially those closer to the time would be able to help determine that the date is accurate as well.
