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.

[EX Q]: 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

[EX Q]: Passage: Corry cleared Bermuda on 25 October 1942 for Casablanca to participate in the Moroccan landings, in the screen of the aircraft carrier . She left Casablanca 16 November for Norfolk and Boston, and after overhaul resumed her coastal and Caribbean operations until 13 February 1943, when she sailed on escort duty from Norfolk for north Africa, returning 6 March for operations in the western Atlantic. On 11 August she sailed for Scotland and operated with the British Home Fleet, cruising once to Norway as providing escort for Ranger in the successful Allied air raid on Bodø, Norway in October 1943 (Operation Leader).

[EX Q]: Passage: The yellow-wattled lapwing was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle. This plate was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Charadrius malabaricus in his catalogue of the Planches Enluminées. The type locality is the Malabar Coast in southwest India. The current genus Vanellus was erected by the French zoologist Mathurin Jacques Brisson in 1760. Vanellus is the Medieval Latin for a "lapwing". It is a diminutive of the Latin vanus meaning "winnowing" or "fan". The species is monotypic.
