Example Input: Question: What was the population of the Hejaz region during The Battle of Badr? Passage:The Battle of Badr (), fought on Tuesday, 13 March 624 CE (17 Ramadan, 2 AH in the Islamic calendar) in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. All knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. There is little evidence outside of these of the battle. There are no descriptions of the battle prior to the 9th century.

Example Input: Question: To what language family belongs the language from which the word "vanga" is from? 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'écorcheur 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.
