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 After several months of occupation duty in France, in late November, the 4th Division was withdrawn to Würzburg, where it was reorganized and reinforced.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: How old is the person Smith got into an altercation with as a teenager? Passage:Smith was born and raised in Brooklyn, New York. He became a wrestling fan in the late 1950s. A childhood friend claimed that they were the first wrestling fans to bring signs to local World Wide Wrestling Federation house shows. Around 1971, Smith also co-founded an unofficial fan club for Freddie Blassie with members wearing homemade "Blassie's Army" T-shirts. As a teenager, Smith had an altercation with Kevin Sullivan while attending a live event at Sunnyside Gardens. Sullivan had been hit with an unknown object at the end of his bout against Davey O'Hannon. Smith, who often cheered for the "heel" wrestlers, had been heckling Sullivan (then a "babyface") throughout the night causing the wrestler to believe that Smith was responsible. The young wrestling fan was brought to the dressing room by building security after the match where he was confronted by Sullivan, Gorilla Monsoon and Arnold Skaaland. Smith denied any wrongdoing and was allowed to leave. Smith continued watching wrestling after moving to Knoxville, Tennessee in the mid-1970s. He eventually met Norvell Austin at a Southeastern Championship Wrestling. Austin later introduced Smith to Rick Conner who agreed to train him.

Question: Who was the second choice goalkeeper? Passage:Knight joined Portsmouth F.C. as an apprentice at the age of 14 and signed a professional contract with the club in 1977. He went on to make his debut for the club a year later, keeping a clean sheet in a 2–0 Football League Third Division win against Rotherham United with Portsmouth's relegation to the fourth tier of English football already confirmed. Knight served as reserve goalkeeper to Peter Mellor for the next three seasons, making eight appearances during Pompey's 1979–80 promotion season, before establishing himself as the team's first choice goalkeeper during the 1981–82 season where he was named the fans' player of the season for the first time. Knight was a member of the team that won the Third Division championship in 1982–83 and was given a debut for the England U21 team in a 1984 UEFA European Under-21 Championship qualifier against Greece at Portsmouth's ground Fratton Park. He made one further appearance for the England U21s against Hungary, before first choice goalkeeper Gary Bailey returned from injury. England went on to win the final tournament, with Knight's Portsmouth teammate Mark Hateley named player of the tournament.
