Input: Consider 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.

Input: Consider Input: Question: How long did the quarterback who had his photo taken after a defeat at Pitt Stadium play for the New York Giants? Passage:The NFL's Steelers played home games at Forbes Field from their 1933 inception to 1957. They first played at Pitt Stadium in 1942, in an exhibition match for U.S.O. charity against the Fort Knox "Armoraiders" on November 15. From 1958 to 1963, the Steelers split home games between Forbes Field and Pitt Stadium. Fans were able to purchase season ticket packages for one site or the other. In 1964, the Steelers began to play home games exclusively at Pitt Stadium, which they continued until moving to the new Three Rivers Stadium in 1970. Of historic note, the iconic photo of New York Giants quarterback Y. A. Tittle, helmet-less, bloodied and kneeling, was taken at Pitt Stadium in 1964 following a Giants' loss to the Steelers on September 20. The photo, taken by Pittsburgh Post-Gazette photographer Morris Berman, now hangs in the Pro Football Hall of Fame.
