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 old was Jennie Jerome when her granddaughter Lady Eden was born? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

Input: Consider Input: Question: Did VItaly Petrov win a race for Renault? Passage:In October 2004, the Midland Group announced its intention to enter Formula One motor racing in 2006, with plans to use a car built by the Italian manufacturer Dallara In January 2005 the group changed plans by purchasing the Jordan Grand Prix team. They kept the yellow-liveried EJ15 cars and declared 2005 to be a year of learning. Under the name Midland F1 Racing, the team made its debut with a brand-new car and livery at the start of the 2006 Formula One season. With this team, Shnaider declared his intention to bring the first Russian driver into the sport, a feat not achieved until Vitaly Petrov's entrance into F1 with Renault, three years after Schnaider sold the team. On 9 September 2006, the team was sold to Spyker Cars for $106.6 million. From the beginning of the 2008 season, the team became known as Force India and remained active until 2018, when a group of consortium led by Lawrence Stroll bought the team in 2018 following a financial collapse that forced Force India to be put under administration. The team currently competes under the Racing Point banner.
