Example Input: Question: When was the place where the Cyclones play home games built? Passage:The 2011 Iowa State Cyclones football team represented Iowa State University in the 2011 NCAA Division I FBS football season. The Cyclones were led by third year head coach Paul Rhoads and play their home games at Jack Trice Stadium. They are a member of the Big 12 Conference. The conference play began with a loss at home to the Texas Longhorns, and ended with a loss at Manhattan, Kansas to the Kansas State Wildcats in the Farmageddon series, with a 3–6 record. The season will likely be remembered for the game against then #2 Oklahoma State Cowboys, who the Cyclones upset in a double-overtime thriller throwing the BCS into "utter chaos" as dubbed by sports media. The Iowa State squad was invited to the first Pinstripe Bowl game, which they were defeated by Rutgers, and the Cyclone's 2011 season came to a close with 6–7 overall record, 3–6 in Big 12 play, finished 8th place.

Example Input: Question: Who is the oldest of Harry Potter's aunt and uncle? Passage:During the summer holidays with his aunt Petunia and uncle Vernon, 15-year-old Harry Potter and his cousin Dudley are attacked by Dementors. After openly using magic to save Dudley and himself, Harry is expelled from Hogwarts, but his expulsion is postponed pending a hearing at the Ministry of Magic. Harry is whisked off by a group of wizards including Mad-Eye Moody, Remus Lupin, and several new faces, including Nymphadora Tonks, a bubbly young Metamophagus (a witch or wizard who can change his or her appearance without a potion or spell), and Kingsley Shacklebolt, a senior Auror, to Number 12, Grimmauld Place, the childhood home of Sirius Black. The building also serves as the headquarters of the Order of the Phoenix, of which Mr. and Mrs. Weasley and Sirius are also members. Ron Weasley and Hermione Granger explain that the Order is a secret organisation led by Hogwarts headmaster Albus Dumbledore dedicated to fighting Lord Voldemort and his followers, the Death Eaters. From the members of the Order, Harry and the others learn Voldemort is seeking an object he did not have prior to his first defeat and assume this object to be a weapon of some sort. Harry learns the Ministry of Magic, led by Cornelius Fudge, is refusing to acknowledge Voldemort's return because of the panic and chaos doing so would cause. Harry also learns the Daily Prophet has been running a smear campaign against him and Dumbledore.
