In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: What year saw the publication of the eleventh edition of the zoological book published by a Swedish naturalist who included the hook-billed vanga in the twelfth edition of the book? Passage:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the hook-billed vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name L'ecorcheur de Madagascar and the Latin Collurio Madagascariensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the hook-billed vanga. Linnaeus included a brief description, coined the binomial name Lanius curvirostris and cited Brisson's work. It is now the only species placed in the genus Vanga that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. The specific name curvirostris is from Latin curvus "curved" and -rostrum "billed". The word "vanga" is the Malagasy name for the species. Two subspecies are recognised.

Example Output: When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson

Example Input: Question: What year did that freshman who led the Sooners' offense first attend the school? Passage:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (53 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 4014, and in 1993, they defeated Texas Tech 4110.

Example Output: With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games

Example Input: Question: How long had the duke of Normandy held that title when he commenced invading England? Passage:In the 11th century, Errand of Harcourt and his three brothers followed William the Conqueror, duke of Normandy, on the Norman invasion of England, and the brothers were installed with English lands. The English Harcourt branch entered the English peerage, as barons then viscounts then earls. At first the Harcourts had lands in Leicestershire, but in 1191 Robert de Harcourt of Bosworth inherited lands of his father-in-law at Stanton in Oxfordshire, which then became known as Stanton Harcourt. The manor of Stanton Harcourt has remained in the Harcourt family to the present day, although from 1756 to 1948 their main residence was at Nuneham House, also in Oxfordshire. Simon Harcourt was created Baron Harcourt in 1711 and Viscount Harcourt in 1721. The third viscount was created Earl Harcourt in 1749, but all titles were extinguished with the death of marshal William Harcourt, 3rd Earl Harcourt, in 1830. His cousin Edward Vernon, Archbishop of York, thus inherited the majority of that branch's lands and titles and took the name and heraldic shield of the English Harcourt family by royal authorisation on 15 January 1831. This created the Vernon-Harcourt branch, descended from a Harcourt woman. The title Viscount Harcourt was created a second time in 1917 for Lewis Harcourt, but the title was again extinguished on the death of his son.

Example Output:
