Example Input: Question: What is the age difference between Cole's husband and the person who helped her recover from malaria? Passage:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson. It is written in the music key of C minor with a time signature in common time and a tempo of 151 beats per minute. Cole's vocal range spans from G to E♭. The basic chord progression of the song is Cm, Cm, Cm, Cm, E♭, B♭, F, Cm, E♭, B♭ and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".

Example Input: Question: When was the organization where Ware set 26 records founded? Passage:Ware grew up in the Galveston, Texas region, hoping to play football at the University of Texas. He said "I was going to Texas. All they had to do was lie to me and tell me I was going to play quarterback once I got there. Thank goodness they told me the truth [that] they were going to move me to defense". After graduating from Dickinson High School, Ware instead played at the University of Houston, where he won the Heisman Trophy in 1989, along with the Davey O'Brien Award, the latter award given to the most outstanding college quarterback of the year. That year, his junior year, he threw for 4,699 yards, 44 touchdowns, and set 26 NCAA records. Many of the records were thanks to the innovative use of the run and shoot offense, which his successor, David Klingler, also used to great effect. The Cougars ended the season ranked the #14 team in the nation by the Associated Press. He then declared for the NFL Draft, foregoing his senior year.
