In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Example Input: Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
Answer: 310
Example Output: How many species of pigeons are there?

Example Input: Passage: In the late 19thcentury, Coventry became a major centre of bicycle manufacture. The industry energised by the invention by James Starley and his nephew John Kemp Starley of the Rover safety bicycle, which was safer and more popular than the pioneering penny-farthing. The company became Rover. By the early 20thcentury, bicycle manufacture had evolved into motor manufacture, and Coventry became a major centre of the British motor industry. The research and design headquarters of Jaguar Cars is in the city at their Whitley plant and although vehicle assembly ceased at the Browns Lane plant in 2004, Jaguar's head office returned to the city in 2011, and is also sited in Whitley. Jaguar is owned by the Indian company, Tata Motors.
Link Information: Tata Motors Limited, formerly Tata Engineering and Locomotive Company (TELCO), is an Indian multinational automotive manufacturing company headquartered in Mumbai, Maharashtra, India. Answer: Mumbai, Maharashtra, India
Example Output: Where was Jaguar's head office located in 2010?

Example Input: Passage: Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Uber die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
