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.

Example Input: Question: Was the #11 seed school that made it to their first Final Four appearance a private school? Passage:The 2011 NCAA Men's Division I Basketball Tournament was the first time since the tournament expanded to 64 teams in 1985 that two mid-majors met in the Final Four. The Butler University Bulldogs returned for their second consecutive appearance after winning the Southeast Regional in New Orleans as a #8 seed. The Virginia Commonwealth University Rams of the Colonial Athletic Association advanced to their first Final Four appearance after winning the Southwest Regional in San Antonio as a #11 seed. VCU became the first team in history to win five games to reach the Final Four, winning the First Four round in its inaugural year. VCU tied LSU in 1986 and fellow CAA team, George Mason, in 2006 as the highest seed to reach the Final Four (#11). The previous time two mid-majors advanced to the same Final Four was the 1979 NCAA Men's Division I Basketball Tournament, when Indiana State of the Missouri Valley and Penn of the Ivy League qualified. Butler is no longer a mid-major due to its membership in the Big East since 2013. VCU has since joined the Atlantic 10, where it has consistently been among the top teams, even following the departure of coach Shaka Smart for Texas in 2015, and his successor, Will Wade, for LSU in 2017.

Example Input: Question: Was the town where Timmerman was stationed larger than the town the the IX corps was defending? Passage:On July 6, 1940, Karl Timmermann enlisted in the U.S. Army. He was stationed at Fort Lewis, Washington and assigned to the 15th Infantry Regiment of the 3rd Infantry Division. After the Japanese military attacked Pearl Harbor, his unit began training for war. The 3rd Infantry Division, with the 41st Infantry Division, were then part of IX Corps. In May 1941, the two divisions moved to the Hunter Liggett Military Reservation where June war games pitted them against Major General Joseph Stilwell's 7th Division and the 40th Division. Large scale maneuvers continued in August on the Olympic Peninsula, with IX Corps defending Tacoma, Washington until the two divisions from California could arrive to assist.
