Example Input: Question: What year did the player who scored four goals against Rad Belgrade retire? Passage:In 1976, led by coach Dragan Bojovic, the club won the second league and again provides a placement in the elite, thanks to the four goals by Jovica Skoro, three by Milomir Jakovljevic and one by Dragisa Cuslovic, which brought the decisive 82 victory over Rad Belgrade, but they relegated again in the same season. In the season 197879, they joined the Yugoslav First League, and in that season, Yugoslav powerhouse Partizan suffered a sensational 30 home defeat from Napredak. In the season 197980, led by coach Tomislav Kaloperovic, Napredak finished the championship as 4th and this in front of several Yugoslav top clubs, and qualified finally for the first time for a European competition, the 198081 UEFA Cup season, but they were eliminated already in the first round by Eastern Germany's club Dynamo Dresden. It got even worse, because in the same season the club finished the league unexpectedly in the last place and relegated to the Yugoslav Second League and competed there until 1988. In the season 198788, Napredak won the East Division of the second league and was promoted to the top tier, but the club could not keep in the first league and relegated for the third time in its history again in the debut season.

Example Input: Question: Which organization that were involved in the building of Toyota's Le Mans Prototype car was established first? Passage:In 1996, Toyota Motor Sports funded the development of an experimental Le Mans Prototype, which was officially known as the TOM'S Toyota LMP. As Toyota were primarily focusing on their Championship Auto Racing Teams (CART) engine, which first ran that year, the LMP project was run on a tight budget of approximately $500,000. Due to this tight budget, the car, christened the "Lumpy", reused Toyota's 3S-GT engine in the 88C Group C specification, which was a 2.1-litre turbocharged straight-four engine, producing ; this engine was coupled to an Xtrac gearbox from a Peugeot Group C car. The chassis tub was designed to be simple but strong, and the bodywork was also simple; the tight budget meant that the LMP never saw a wind tunnel. The bodywork was designed to minimize lift over the upper body of the car, and had much simpler brake cooling than on most Le Mans Prototypes; the radiator ducts were used, via a scoop, to cool the brakes. After the LMP was completed, Tom Kristensen tested it on at least one occasion, whilst project director Andy Thorby recalled it being tested a total of three times; he stated that the car was very reliable, had lower fuel consumption than the 88C Group C car had (with the same engine), and that it also appeared to be quick. Following the completion of the tests, the car was dispatched to Toyota Team Europe's Cologne workshop, stored under a tarpaulin and eventually destroyed. Toyota would return to sportscar racing in 1998, with the Andre de Cortanze-designed Toyota GT-One.
