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'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.

Input: Consider Input: Question: Did the infant inside the box eventually grow and marry? Passage:Taking the earliest first, Euripides Ion, lines 2223; 484485, mentions her, but in the Moses Hadas and John Mclean 1960 Bantam Classics translation they have Euripides say respectively: "(Athena) gave Erichthonius to Aglaurus' daughters (not sisters) to keep." and later, speaking of "a haunt of Pan": "There the daughters of Aglaurus still tread the measures of their dance, on the green lawns before the shrine of Pallas (Athena)...".According to the Bibliotheca, Hephaestus attempted to rape Athena but was unsuccessful. His semen fell on the ground, impregnating Gaia. Gaia did not want the infant Erichthonius, so she gave the baby to the goddess Athena. Athena gave the baby in a box to three womenAglaurus and her two sisters Herse and Pandrosusand warned them to never open it. Aglaurus and Herse opened the box. The sight of the infant caused them both to go insane and they threw themselves off the Acropolis, or, according to Hyginus, into the sea.
