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.

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
How many species of pigeons are there?

Passage: The Busy World of Richard Scarry is an American/Canadian/French animated children's television series, produced by CINAR Animation (now known as DHX Media, previously Cookie Jar Entertainment) and France Animation in association with Paramount Television, which aired from 1994 to 1997, first on Showtime, later on Nickelodeon, and ran for 65 episodes. The television series was based on the books drawn and written by Richard Scarry. Reruns of the show formerly aired in syndication as part of the Cookie Jar Kids Network block, but the show now continues to air on the Cookie Jar Toons block on This TV until October 26, 2013. Reruns of the show aired on Qubo from May 13, 2013, to September 25, 2016. However, it returned to Qubo on March 28, 2017, as part of the network's Night Owl block until May 26, 2018, and currently airs on Light TV.
Link Information: Formed in 2006 by the merger of Decode Entertainment and the Halifax Film Company, Answer: 2006
When was the company now known as DHX Media first founded?

Passage: Anomocephaloidea is a clade (evolutionary grouping) of anomodont therapsids that existed in Gondwana during the Middle Permian and includes two species, Anomocephalus africanus from South Africa and Tiarajudens eccentricus from Brazil, both of which are characterized by large body size and teeth that fit tightly together or occlude. Anomocephaloidea is among the most basal groups of anomodonts, the other being Venyukovioidea, which differs in being a Laurasian clade of mostly small-bodied species. Anomocephaloidea was named in 2011 with the discovery of Tiarajudens; Anomocephalus had been known since 1999, but was unique among anomodonts until Tiarajudens was described. Both Anomocephalus and Tiarajudens were herbivores, although the latter possessed a pair of saber-like canine teeth that may have been used in display or combat with other individuals of the same species. Although Anomocephaloidea was short-lived and had a limited geographic distribution, it was part of a larger evolutionary radiation of anomodonts in the Middle Permian characterized by the evolution of a diverse array of new morphological characteristics and ecological roles, and that would later lead to the rise of Dicynodontia, the largest clade within Anomodontia and one of the most successful groups of tetrapods in the Permian.
Link Information: The Guadalupian is the second and middle series or epoch of the Permian. Previously called Middle Permian, the name of this epoch is part of a revision of Permian stratigraphy for standard global correlation. The name "Guadalupian" was first proposed in the early 1900s, and approved by the International Subcommission on Permian Stratigraphy in 1996.
References to the Middle Permian still exist. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains in New Mexico. The International Chronostratigraphic Chart (v2018/07) provides a numerical age of 272.3 0.5 259.8 0.4 Mya. Answer: 272.3 0.5 259.8 0.4 Mya
When did the time period in which Anomocephaloidea existed begin?
