[EX Q]: Question: Is Carl Linnaeus older than the French zoologist who introduced the horned screamer in the genus Anhima? Passage:The horned screamer was described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae. He introduced the binomial name Palamedea cornuta. The horned screamer is now the only species placed in the genus Anhima that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The specific epithet cornuta is the Latin word for "horned". The German naturalist Georg Marcgrave had used the Latin name Anhima in 1648 for the horned screamer in his Historia naturalis Brasiliae. The name was from the word for the bird in the Tupi language of South America.

[EX Q]: Question: Who was the president of Atlantic Records in 1961? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.

[EX Q]: Question: When did the Beatles stop using their first band name? Passage:The recordings made by the Beatles, a rock group from Liverpool, England, from their inception as the Quarrymen in 1957 to their break-up in 1970 and the reunion of their surviving members in the mid-1990s, have huge cultural and historical value. The studio session tapes are kept at Abbey Road Studios, formerly known as "EMI Recording Studios," where the Beatles recorded most of their music. While most have never been officially released, their outtakes and demos are seen by fans as collectables, and some of the recordings have appeared on countless bootlegs. Until 2013, the only outtakes and demos to be officially released were on The Beatles Anthology series and its tie-in singles, and bits of some previously unreleased studio recordings were used in  video game as ambient noise and to give songs studio-sounding beginnings and endings. In 2013, Apple Records released the album The Beatles Bootleg Recordings 1963, which includes previously unreleased outtakes and demos from 1963, to stop the recordings from falling into the public domain.
