[EX Q]: Question: How long had Central States Wrestling been in business the year Robertson won the NWA Central States Television Championship? Passage:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.

[EX Q]: Question: How many different MLB teams did the player who had nine hits, all singles, and a .529 batting average play for throughout his career? Passage:On the mound, the Reds relied on left-handers Don Gullett and Fred Norman to pacify the Yankee hitters in Games 1 and 2, respectively. Gullett had come back from a mid-season injury to start Game 1 but had to leave the game in the eighth inning due to a twisted ankle while Norman out-pitched ace Hunter in Game 2. Game 3 in New York pitted effective 1976 NL Rookie of the Year Pat Zachry for the Reds against newly acquired Yankee, Dock Ellis. Ellis only lasted innings, exiting in the fourth after a home run by Driessen. Game 4 was delayed a day due to rain, but the Reds were ready for the sweep. Bench's two-run home run gave the Reds a 31 lead. In the bottom of the eighth, a frustrated Billy Martin threw a baseball from the dugout onto the field towards home plate umpire Bill Deegan, causing his ejection from the game. In the ninth, Bench's second home run followed by back-to-back doubles by Cesar Geronimo and Dave Concepcion made the score 72 and essentially blew the game open. The Cincinnati Reds outscored the New York Yankees, 228, and became the first NL team to repeat as World Champions since the 19211922 New York Giants. The Reds did not make a single offensive or defensive substitution (save pitching changes) during the entire series. Bench would claim the MVP of the series hitting .533 with two home runs and six runs batted in. His catching counterpart, Thurman Munson, had nine hits, all singles, and a .529 batting average.
