Input: Consider Input: Question: What other teammates had Roberts had before partnering with Lawson? Passage:Lawson accepted an offer from Yamaha to contest the 500cc World Championship as Kenny Roberts' teammate for the 1983 season. Lawson spent the 1983 season learning the ropes of the Grand Prix circuit. In 1984, Lawson began winning regularly and won the 1984 World Championship. It would mark the first of four world titles Lawson would go on to win. In 1985, he won the prestigious Imola 200 pre-season race. After winning two more titles for Yamaha in 1986 and 1988, Lawson shocked the racing world by announcing he would be leaving Yamaha to sign with their arch-rivals Rothmans Honda as teammate to his own archrival, Australia's 1987 World Champion Wayne Gardner. By switching teams, Lawson also fulfilled his desire to work with Erv Kanemoto. After Gardner crashed and broke his leg during the third round at Laguna Seca, Lawson went on to win the 1989 title for Honda, becoming the first rider to win back-to-back championships on machines from different manufacturers. By winning with both Yamaha and Honda, Lawson silenced his critics who believed he would not be as successful away from the factory Marlboro Yamaha team.

Input: Consider Input: Question: Was the stadium where Swann's most notable performance occurred built before 1990? Passage:For 2003, he signed with the Baltimore Orioles and again spent a few games in the majors. His most notable performance as a major leaguer occurred at Camden Yards on September 18, 2003. An attempt to avoid Hurricane Isabel by changing the game's start time from 7:05 pm (ET) to 12:35 pm proved futile as the contest was played entirely in a downpour. With the score tied at one, Swann opened the bottom of the fifth inning with a double off Mike Mussina. When Brian Roberts hit a one-out single to left field, Orioles third-base coach Tom Trebelhorn had initially waved Swann home. He abruptly put up the stop sign when left fielder Hideki Matsui quickly threw the ball to third baseman Aaron Boone. Swann, who was too far past third base, got caught in a rundown and was tagged out. When the inning ended with the Orioles failing to score a run, the match was suspended and replayed in its entirety eight days later on September 26 as part of a twi-night doubleheader at Yankee Stadium. The Orioles would have had a 2–1 victory had Swann successfully crossed home plate because the game became official upon the completion of the fifth inning.
