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: Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.

Example Input: Passage: The knifetooth sawfish (Anoxypristis cuspidata), also known as the pointed sawfish or narrow sawfish, is a species of sawfish in the family Pristidae, part of the Batoidea, a superorder of cartilaginous fish that includes the rays and skates. Sawfish display a circumglobal distribution in warm marine and freshwater habitats. Their extant biodiversity is limited to five species belonging to two genera (Pristis and Anoxypristis). The sawfishes are characterised by the long, narrow, flattened rostrum or extension on their snout. This is lined with sharp transverse teeth, arranged in a way that resembles the teeth of a saw. It is found in the shallow coastal waters and estuaries of the Indo-West Pacific, ranging from the Red Sea and the Persian Gulf to southern Japan, Papua New Guinea and northern Australia. It is the only living member of the genus Anoxypristis, but was previously included in the genus Pristis. Compared to that genus, Anoxypristis has a narrower rostral saw with numerous teeth on the distal part and no teeth on the basal one-quarter (toothless section about one-sixth in juveniles). This endangered species reaches a length of up to .
