Input: Consider Input: Question: What city was Jet Ski Lady's last race in? Passage:Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained thoroughbred racehorse, best known for winning The Oaks in 1991. In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races. After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse. Her winning margin of ten lengths was the second-widest in the race's history and her starting price of 50/1 made her the equal longest-priced winner of the Oaks on records. She subsequently finished second in both the Irish Oaks at the Curragh and the Yorkshire Oaks at York. She was retired to stud after finishing unplaced in the Prix de l'Arc de Triomphe.

Input: Consider Input: Question: What was the age difference between Ronald Reagan and his running mate? Passage:In the 1976 Republican primary, President Ford faced a challenge from former California Governor Ronald Reagan, who selected Richard Schweiker as his running mate. Though Thurmond backed Reagan's candidacy, he, along with North Carolina Senator Jesse Helms, led efforts to oust Schweiker from the ticket. During the subsequent general election, Thurmond appeared in a campaign commercial for incumbent U.S. President Gerald Ford in his race against Thurmond's fellow Southerner, former Georgia Governor Jimmy Carter. In the commercial, Thurmond said Ford (who was born in Nebraska and spent most of his life in Michigan) "sound[ed] more like a Southerner than Jimmy Carter". After President-elect Carter nominated Theodore C. Sorensen as his choice to become Director of the Central Intelligence Agency, Thurmond expressed reservations and fellow Senator Jake Garn said he believed Thurmond would not vote for the nomination. Sorensen withdrew from consideration days later, before a vote could be had.
