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.

Question: What date did the division land on Utah Beach? Passage:The division arrived in Liverpool on April 17 and began training in amphibious operations. After training in the United Kingdom from 17 April 1944, the 79th Infantry Division landed on Utah Beach, Normandy, 12–14 June and entered combat 19 June 1944, with an attack on the high ground west and northwest of Valognes and high ground south of Cherbourg. The division took Fort du Roule after a heavy engagement and entered Cherbourg, 25 June. It was around this time that Corporal John D. Kelly and First Lieutenant Carlos C. Ogden, both of the 314th Infantry Regiment, were awarded the Medal of Honor. It held a defensive line at the Ollonde River until 2 July 1944 and then returned to the offensive, taking La Haye du Puits in house-to-house fighting, 8 July. On 26 July, the 79th attacked across the Ay River, took Lessay, crossed the Sarthe River and entered Le Mans, 8 August, meeting only light resistance. The advance continued across the Seine, 19 August. Heavy German counterattacks were repelled, 22–27 August, and the division reached the Therain River, 31 August. Moving swiftly to the Franco-Belgian frontier near St. Amand (east of Lille), the division was then moved to XV Corps in eastern France, where it encountered heavy resistance in taking Charmes in street fighting, 12 September. The 79th cut across the Moselle and Meurthe Rivers, 13–23 September, cleared the Forêt de Parroy in a severe engagement, 28 September–9 October, and attacked to gain high ground east of Emberménil, 14–23 October, when it was relieved, 24 October.

Question: Who wrote the first song that Graham Clark learned to sing? Passage:Graham Clarke was born in Holy Name Medical Center in Teaneck, New Jersey on July 11, 1970. Clarke's parents, Lorain Maria Clarke (née Meola), a homemaker, and Thomas Michael "Moose" Clarke, a stockbroker were married in 1960 and had three children before Graham: Thomas in 1961, Dennis in 1962, and Martin in 1965. He spent the first seven years of his life in a split-level home in Dumont, New Jersey. He was frequently in the room when his older brother Tommy would have guitar lessons with musician Bob Berger. Bob noted one time when a screaming Graham had scarlet fever "That boy's screaming on key! That's a C note." Such exposure to music had an obvious influence on him and there is an oft-told family story that claims the first song Graham ever learned to sing was "Me and Julio Down by the Schoolyard," a popular song Tommy was learning on the guitar at the time. At the age of seven, his family moved one town over to Oradell, where he attended St. Joseph Grammar School, and later Bergen Catholic High School. Neither school had a music program so Graham taught himself how to play the guitar using his brother's old fake books.
