[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.
 Question: How many species of pigeons are there?
[EX A]: Answer: 310

[EX Q]: Passage: In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.
 Link Information: Sarah Vaughan with Michel Legrand is a 1972 studio album by Sarah Vaughan, arranged by Michel Legrand Question: What year did Vaughan's second album with Mainstream come out?
[EX A]: Answer: 1972

[EX Q]: Passage: MCA embarked on a big marketing campaign to tout Willis after she recorded her first album on the label, the 1990 album Well Travelled Love. MCA ensured that Willis was interviewed by several national magazines including unusual venues like Vogue and Mademoiselle. Her voice appeared in the 1991 Ridley Scott-produced movie Thelma and Louise, singing "Little Honey." Willis also had a small part in Tim Robbins’ 1992 film Bob Roberts. Willis appears as the young woman standing in a shallow stream in Dwight Yoakam's video of "A Thousand Miles from Nowhere," as well as a member of Vince Gill's "pickup band" in his Don't Let Our Love Start Slippin' Away video. She was also nominated for Top New Female Vocalist of the year at the 1993 ACM Awards along with Faith Hill and Lari White (Hill wound up winning the award). Despite of all the publicity and positive reviews from most reviewers, Well Travelled Love and Willis’s subsequent albums for MCA (Bang Bang in 1991 and Kelly Willis in 1993) sold modestly and received very little radio play. During this time, Willis felt uncomfortable with the way she was marketed by MCA. In 1994, MCA released Willis from her contract.
