question:
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.

question:
Question: How big is the county that PA 741 begins in? Passage:PA 741 begins at an intersection with PA 722 in the borough of East Petersburg in Lancaster County, heading to the south on two-lane undivided Lemon Street, which is unsigned and locally maintained. The road passes homes prior to crossing into East Hempfield Township, where it becomes Rohrerstown Road and continues through industrial parks. PA 741 gains a center left-turn lane and becomes signed at the Commercial Avenue intersection. The route continues to an interchange with PA 283, at which point it becomes state-maintained. The road crosses the Little Conestoga Creek into Manheim Township after PA 283. The route becomes two lanes again and turns east prior to turning southwest and crossing the Little Conestoga Creek back into East Hempfield Township. At this point, PA 741 becomes McGovernville Road and comes to a bridge over Norfolk Southern's Lititz Secondary and Amtrak's Keystone Corridor. The road passes a mix of homes and woods as it comes to the Harrisburg Pike intersection, where it makes a turn to the south onto Rohrerstown Road, a three lane road with a center left-turn lane. PA 741 passes homes to the west and a branch of Lancaster General Hospital to the east prior to coming to the US 30 interchange. In the area of the interchange, PA 741 is briefly a divided highway. Following US 30, the route becomes a two-lane undivided road and passes residences prior to crossing Norfolk Southern's Columbia Secondary and entering the residential and commercial community of Rohrerstown. Here, PA 741 crosses PA 23. After leaving Rohrerstown, the road passes a mix of farms and businesses prior to an intersection with PA 462.

question:
Question: Which Zwart partner was born first? Passage:Mike Phillips attempted to enter an A410 at the 24 Hours of Daytona in 2001, but did not attend the race. The Sports Racing World Cup had been renamed to the FIA Sportscar Championship, but the A410, now driven by Lupberger and Ben Collins, started the season as it had finished 2000; with a retirement, although it did last for 74 laps before blowing its engine with half an hour to go at Barcelona. Next up was the Donington Park of the European Le Mans Series, which saw both A410s entered; although the A410 of Patrick Lemarié did not make the start of the race, due to engine problems, Lupberger and Collins were classified 23rd, having retired after 54 minutes – and 35 laps – due to another gearbox problem. The 1000 km of Monza, part of the FIA Sportscar Championship, saw the first success for the A410; Collins and Lupberger brought their car home in second, 7 seconds behind the Ferrari 333SP-Judd of Giovanni Lavaggi and Christian Vann. The upturn in form continued at Spa-Francorchamps, where Collins and Lupberger brought the A410 home in fourth, a lap down, but having set the second fastest lap of the race. Lupberger and Collins were partnered by Harri Toivonen for the 24 Hours of Le Mans in the A410-001 chassis, whilst Zwart partnered Xavier Pompidou and Scott Maxwell in the other; neither finished, as the A410-001 retired due to fuel pump issue after 11 hours and 134 laps, and the other car crashed out after 15 hours and 66 laps. Having returned to the FIA Sportscar Championship, Collins and Lupberger took a pair of fourth-place finishes, at Brno and Magny-Cours. The team went even better at Donington Park; Collins and Lupberger won by almost a minute, for the car's maiden victory. The penultimate round of the season, held at Mondello Park, was a little less successful, as the team finished ninth overall, and sixth in the SR1 class. In the final race of the season, held at the Nürburgring, the car was disqualified from third place due to issues with its dimensions. Team Ascari finished the season in fourth, with 71 points; nine behind Racing for Holland in third, but 30 ahead of R&M in fifth. The team's one European Le Mans Series race resulted in them being classified in eighth, with 11 points.
