Task: Question Answering
Input (English): Passage: Tahr -- Tahrs are three species of large Asian artiodactyl ungulates related to the wild goat. Until recently the three species were believed to be closely related and were placed in a single genus, Hemitragus. Genetic studies have proven that the three tahrs are not as closely related as previously thought. Now they are considered as members of three separate monotypic genera; Hemitragus is now reserved for the Himalayan Tahr; Nilgiritragus for the Nilgiri Tahr; and Arabitragus for the Arabian Tahr.
Question: nilgiri himalyan and arabian are types of tahr
