Example Input: Question: Which of the people that Sir Simon Fraser fought with during the Scottish Wars of Independence was the oldest? Passage:During the Scottish Wars of Independence, Sir Simon Fraser, known as "the Patriot", fought first with the Red Comyn, and later with Sir William Wallace and Robert the Bruce. Sir Simon is celebrated for having defeated the English at the Battle of Roslin in 1303, with just 8,000 men under his command. At the Battle of Methven in 1306, Sir Simon Fraser led troops along with Bruce, and saved the King's life in three separate instances. Simon was allegedly awarded the 3 Crowns which now appear in the Lovat Arms for these three acts of bravery. He was however captured by the English and executed with great cruelty by Edward I of England in 1306, in the same barbaric fashion as Wallace. At the Battle of Bannockburn in 1314, Sir Simon's cousin, Sir Alexander Fraser of Touchfraser and Cowie, was much more fortunate. He fought at Bannockburn, married Bruce's sister, and became Chamberlain of Scotland. The Frasers of Philorth who are chiefs of the senior Clan Fraser trace their lineage from this Alexander. Alexander's younger brother, another Sir Simon Fraser, was the ancestor of the chiefs of the Clan Fraser of Lovat. This Simon Fraser was killed at the Battle of Halidon Hill in 1333, along with his younger brothers Andrew and James.

Example Input: Question: When was the Group C category started? Passage: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.
