Example Input: Question: Did Louis XIV's cousin have any siblings? Passage:After Louis XIV's marriage to Maria Theresa of Spain on 9 June 1660, Queen Anne turned her attention to the marriage of Philippe. He had previously been encouraged to court his older cousin the Duchess of Montpensier, eldest daughter of Gaston and his first wife Marie de Bourbon. Known as Mademoiselle at this time, she had an immense private fortune and had previously rejected suitors such as Charles II of England. Born in 1627, she was the sole heiress of her mother who died in childbirth. Mademoiselle declined the union, complaining that Philippe always stayed near his mother as if he was "like a child". Mademoiselle instead remained unmarried. Philippe would marry instead another first cousin, Princess Henrietta of England, youngest child of King Charles I of England and his wife Queen Henrietta Maria, who was Philippe's aunt and had taken refuge at the court of France after the birth of Princess Henrietta in 1644. They lived at the Palais Royal and at the Palais du Louvre. In 1660, after the restoration of the House of Stuart to the throne of England under her brother Charles II, Princess Henrietta returned to England to visit her sister, the Princess of Orange, who later caught smallpox and died. The French court officially asked for Henrietta's hand on behalf of Philippe on 22 November 1660 while she was in England. The couple signed their marriage contract at the Palais Royal on 30 March 1661. The ceremony took place the next day in the same building in front of select members of the court. The dowry promised was a huge 840,000 livres. Known as Henriette d'Angleterre in France, and Minette to her intimates, she was known officially as Madame and was ever popular with the court. Court gossip later said that the king was the father of Henrietta's first child. Henrietta's very open flirting is said to have caused a jealous Philippe to retaliate by beginning to flaunt his sexuality openly in a less than accepting era.

Example Input: Question: In what country is the Nikos Kazantzakis Stadium located? Passage:The "Nikos Kazantzakis" Stadium (), formerly known as Ergotelis Stadium and more commonly as Martinengo Stadium, is a football stadium located on the Martinengo bastion, part of the fortifications of Heraklion, on the island of Crete. It is named after Modern Greek literature giant Nikos Kazantzakis, whose grave is also located on the same bastion. It is part of the Ergotelis Athletic Centre, a sport facilities complex owned by Greek multi-sport club Ergotelis. Built in 1946, as Ergotelis Stadium (), it was the traditional home ground of Greek football club Ergotelis until 2004, when the club moved to the Pankritio Stadium, Heraklion's largest and most modern sports venue. The complex currently houses the Ergotelis Youth Academy, the largest youth sports academy on the island of Crete, and one of the largest in Greece, while the stadium itself is still used as the home ground of multiple Heraklion football clubs playing in the Heraklion Football Clubs Association amateur league system. It has a capacity of about 1,000 spectators, of which approximately 600 can be seated.

Example Input: Question: What other voice work was done by the person who voiced Ed Grimley's pet rat? Passage:Episodes of the show often featured Ed Grimley in several adventures, which start out as mundane, but turn very surreal and cartoonish, interspersed with science lessons from The Amazing Gustav Brothers, Roger and Emil, and a live-action segment with a "scary story" titled The Count Floyd Show presented as a show-within-a-show by Grimley's favorite television host, SCTV's Count Floyd (played by SCTV cast member Joe Flaherty). Grimley's fellow cartoon characters included Grimley's landlord Leo Freebus (voiced by Jonathan Winters), Leo's wife Deidre (voiced by Andrea Martin), his ditzy, amateur actress neighbor Ms. Malone (voiced by Catherine O'Hara; a female character by the name of Ms. Malone did appear on an SNL version of an Ed Grimley sketch on the season ten episode hosted by Alex Karras, but Ms. Malone was played by that episode's musical guest Tina Turner), and her little brother Wendell (voiced by Danny Cooksey). Ed owns a goldfish named Moby and a clever pet rat named Sheldon (voiced by Frank Welker). At the end of each episode, Ed would write in his diary about what happened in his day.
