Question: How many divisions did von Reichenau command? Passage:During the Battle of France in 1940, the division came under the command of Erich Hoepner's XVI Panzer Corps, part of von Kleist's Panzer Group in the 6th Army commanded by Walther von Reichenau. After a blitzkrieg assault through Liege and Charleroi, it reached the area of Bethune, where it fought against the British Expeditionary Force in what became known as the battle of Dunkirk. However, due to Adolf Hitler's orders, it did not manage to capture Dunkirk itself. In early June 1940, the division managed to cross a large part of France in several days. By the time that the cease fire was signed, it had reached Grenoble almost unopposed. After several months of occupation duty in France, in late November, the 4th Division was withdrawn to Wurzburg, where it was reorganized and reinforced. The 36th Panzer Regiment was detached and assigned to the newly formed 14th Panzer Division, while the 103rd Artillery Regiment was reinforced with a third battalion.

Question: Which organization was created first, the PCF or the SFIO? Passage:Despite its name, the coalition was on the right wing of French politics; for a long time, the French republican right has refused to call itself "right" since the right-wing in France has historically been associated with monarchism (this practice is known as sinistrisme). It was subsidised by French employers, who saw in it the best defense against Communism and the defender of economic liberalism, in a context marked by various nationalizations supported by the French Communist Party (PCF), the French Section of the Workers' International (SFIO) and the Gaullist movement. Employers conceived the RGR as such until at least the 1951 creation of the National Centre of Independents and Peasants (CNIP) gathering independent conservative deputies. During the 1956 legislative campaign, it became a political party led by Edgar Faure and Radicals who refused to join the Republican Front coalition.
