Example Input: Question: Which race that Frankel won in his four-year-old season had a higher purse? Passage:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 120, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

Example Input: Question: How many people live in the city that Hardy made his WWF debut in? Passage:Hardy cites Sting, The Ultimate Warrior, and Shawn Michaels as his childhood inspirations to wrestle. He started on World Wrestling Federation (WWF) television as a jobbera wrestler who consistently loses to make his opponents look stronger. His first WWF match was against Razor Ramon on May 23, 1994 in Youngstown, Ohio, with Randy Savage mentioning on commentary, "Welcome to the big time". His ringname that night, Keith Davis, was the name of Razor's scheduled jobber, who backed out on short notice. Gary Sabaugh, who had brought Hardy in a group along with Davis, suggested him to agent Tony Garea, who agreed after Hardy claimed he was 18 (he was in fact, only 16). The next day, he wrestled under his real name against The 123 Kid, and the match aired on the June 25 episode of Superstars. He occasionally wrestled as a jobber as late as 1997 (including a match against Rob Van Dam during the ECW "invasion" storyline that had Hardy billed as being from Virginia instead of Cameron, North Carolina) before beginning his first major run in 1998.
