question:
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.
 Question: How many species of pigeons are there?

Passage: After school, Greg settled into a life of steady productivity, while living on the proceeds of his shares of The Economist. Working in close association with A. H. Bullen, he produced Pastoral Poetry and Pastoral Drama (1906), the first edited version of the account books of Philip Henslowe (1906–8) and the papers of Edward Alleyn. The latter two works provided him with a knowledge of Renaissance theatrical conditions perhaps rivaled only by E. K. Chambers, and this knowledge he applied to the publications of the Malone Society, which he served as general editor between 1906 and 1939. He served as Librarian of Trinity College, 1907–13, resigning after his marriage to his cousin Elizabeth Gaskell. As an independent scholar, Greg produced editions of The Merry Wives of Windsor (1910), Robert Greene's Orlando Furioso and George Peele's The Battle of Alcazar (published together, 1923), and Sir Thomas More (1911). He returned to specific editing with work on Doctor Faustus (1950). Greg also wrote on the material conditions of Renaissance theater and publishing; his work in this regard includes Dramatic Documents from the Elizabethan Playhouses (1931) and English Literary Autographs, 1550–1650 (1932). The Variants in the First Quarto of King Lear (1940) offered a careful examination of this printing. He also wrote hundreds of reviews, including a notably caustic rejection of J. Churton Collins's 1905 Oxford edition of Robert Greene.

question:
Passage: However, the 1st Canadian Infantry Division took part in the Italian Campaign, participating in the Moro River Campaign and the Battle of Ortona in December 1943 as part of British V Corps and it was not until the fourth Battle of Monte Cassino (Operation Diadem) in May 1944 that I Canadian Corps fought its first battle as a corps. The Eighth Army held the Corps in reserve until after the Gustav defences in the Liri valley had been broken and then brought it forward to assault successfully the next defensive line, the Hitler Line, shortly before the Allied capture of Rome in early June. Having taken part in the Allies' northward advance to Florence, the Corps then took part in Operation Olive, the assault on the Gothic Line in September 1944 before being transported during January–February 1945 in Operation Goldflake to rejoin the rest of the First Canadian Army in Belgium and the Netherlands. There the Corps participated in the campaign to complete the liberation of the Netherlands. On May 6, 1945 at Wageningen, Lieutenant-General Foulkes received the final surrender by Colonel General Johannes Blaskowitz of all remaining German forces still active in the Netherlands. The Corps was deactivated on July 17, 1945 as part of general demobilization.
