Input: Question: How many other children did Drona's father have other than her? Passage 1:Drupada, son of King Prishata, and Drona study together under the tutelage of Rishi Bhardwaja, Drona's father. They become great friends and Drupada assures Drona that once he becomes king, he will share half of his kingdom with Drona. While Drupada becomes a king after the death of his father, Drona lives a life of poverty. Drona approaches Drupada for help; Drupada, now conscious of the difference of status between them, refuses to acknowledge Drona's friendship and shuns Drona, calling him a beggar. Drona is later employed by Bhishma to train the Kuru princes. After the military education of the Kauravas and the Pandavas ends, as his gurudakshina, Drona asks the princes to defeat and capture Drupada. Firstly, all the Kauravas, along with Karna, attack Drupada, but Drupada defeats all of them. Then the Pandavas led by Arjuna defeat Drupada, binding him in ropes and bringing him to Drona. Drona sets Drupada free, but retains half of the kingdom that had been promised to him. Humiliated, Drupada seeks vengeance but he realizes that he cannot match Drona's might. So, Drupada performed the Putrakameshti yajna to beget a son who could slay Drona. From the fire of the yajna, twins Dhrishtadyumna and Draupadi are born. Years later, Draupadi married Arjuna and later in the Mahabharata war, Dhrishtadyumna beheaded Drona.

Passage 3:In 1982, Dome built the RC82 as their first effort in the new Group C category of sports car racing. The chassis was built by March Engineering, whilst the engine was a 3.3-litre Cosworth DFL V8 engine. Dome, with sponsorship from Amada, debuted the car at the 1982 6 Hours of Silverstone, and selected Chris Craft, Raul Boesel and Eliseo Salazar to drive it. It would not prove to be a successful debut, as the car succumbed to fuel pressure issues after 116 laps. Dome then entered Craft and Salazar at the 24 Hours of Le Mans, but the suspension mounting failed after 85 laps, and the team were forced to retire. The RC82 was not used again until the 1983 24 Hours of Le Mans; Nick Mason joined the team, but the car lasted 75 laps before succumbing to clutch failure. Following the race, the RC83 made its debut in the 1000 km of Fuji, with the factory phasing out the RC82.
