Input: Consider Input: Question: Are both of the band members who put out the album "Flags" still alive? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Input: Consider Input: Question: When was the theatre below where Simon did freelance work built? Passage:There, Simon took a room at the boarding house Haddon Hall, in the Morningside Heights neighborhood of Manhattan, near Columbia University. At the suggestion of the art director of the New York Journal American, he sought and found freelance work at Paramount Pictures, working above the Paramount Theatre on Broadway, retouching the movie studio's publicity photos. He also found freelance work at Macfadden Publications, doing illustrations for True Story and other magazines.

That day, Simon received his first comics assignment, a seven-page Western.

Input: Consider Input: Question: Which of Joseph Reinach's two brothers is the oldest? Passage:He was born in Paris. His two brothers Salomon Reinach and Théodore Reinach would later be known in the field of archaeology. After studying at Lycée Condorcet, he was called to the bar in 1887. He attracted the attention of Léon Gambetta by writing articles on Balkan politics for the Revue bleue, and joined the staff of the Republique française. In Gambetta's grand ministère, Reinach was his secretary and tried to obtain a partial revision of the constitution and list proportional representation. In the République française he waged a steady war against General Boulanger, which resulted in three duels, one with Edmond Magnier and two with Paul Déroulède. Between 1889 and 1898, he sat for the Chamber of Deputies for Digne.
