Task: Question Generation
Input (English): Passage: As the last chord of the "Sgt. Pepper" reprise plays, an acoustic guitar strumming offbeat quavers begins, introducing what Moore describes as "one of the most harrowing songs ever written". "A Day in the Life" consists of four verses by Lennon, a bridge, two aleatoric orchestral crescendos and an interpolated middle part written and sung by McCartney. The first crescendo serves as a segue between the third verse and the middle part, leading to a bridge known as the "dream sequence". The idea to use an orchestra was McCartney's; he drew inspiration from Cage and Stockhausen. The 24-bar crescendos feature forty musicians selected from the London and Royal Philharmonic Orchestras and tasked with filling the space with what Womack describes as "the sound of pure apocalypse". Martin said that Lennon requested "a tremendous build-up, from nothing up to something absolutely like the end of the world". Lennon recalled drawing inspiration for the lyrics from a newspaper: "I was writing the song with the Daily Mail propped up in front of me at the piano ... there was a paragraph about 4000 [pot]holes in Blackburn, Lancashire". For "A Day in the Life", he wanted his voice to sound like Elvis Presley on "Heartbreak Hotel". Martin and Emerick obliged by adding 90 milliseconds of tape echo. Womack describes Starr's performance as "one of his most inventive drum parts on record", a part that McCartney encouraged him to attempt despite his protests against "flashy drumming". The thunderous piano chord that concludes the track and the album was produced by recording Lennon, Starr, McCartney and Evans simultaneously sounding an E major chord on three separate pianos; Martin then augmented the sound with a harmonium. The final piano chord was recorded 12 days later. Riley characterises the song as a "postlude to the Pepper fantasy ... that sets all the other songs in perspective", while shattering the illusion of "Pepperland" by introducing the "parallel universe of everyday life". MacDonald describes the track as "a song not of disillusionment with life itself, but of disenchantment with the limits of mundane perception".As "A Day in the Life" ends, a 15-kilohertz high-frequency tone is heard; it was added at Lennon's suggestion with the intention that it would annoy dogs. This is followed by the sounds of backwards laughter and random gibberish that was pressed into the record's concentric run-out groove, which loops back into itself endlessly on any record player not equipped with an automatic needle return. Lennon can be heard saying, "Been so high", followed by McCartney's response: "Never could be any other way.".
Output (English): What is the name of the specific sound element at the end of "A Day in the Life"that was was added at Lennon's suggestion with the intention that it would annoy dogs?
