Input: Consider Input: Question: How long had A&M Records been in business at the time the Carpenters signed a contract with them? Passage:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.

Input: Consider Input: Question: Was Guajardo or Lagarde older when they joined EMLL? Passage:Despite being forced to retire from pro boxing Diaz kept in shape by lifting weights at a local gym. The gym owner was impressed with Diaz physique and work ethics and recommended he become a luchador. Diaz was originally trained by Ray Carrasco and later also trained under Rogelio de la Paz, Genaro Contreas, Raul Rojas and Daniel Garcia; the latter would later be famous under the name of "Huracan Ramirez". Diaz made his professional wrestling debut in 1954, using the ring name "El Pelon" (Spanish for "Baldy") Chato Diaz, then later on worked under names such as "Indio" Mendoza, El Rayo Rojo and El Hombre del Rayo Rojo. He also worked for a while as an enmascarado (masked) character called Gargantua between 1954 and 1955. In 1955 Diaz came up with the ring name "Ray Mendoza" after his mentor Ray Carrasco and his wife's maiden name Mendoza. As Mendoza he quickly forged a very effective Rudo character ("bad guy") by using well developed physique and charisma to create a ring character that the fans loved to hate. In 1956 Mendoza began working for Salvador Lutteroth's Empresa Mexicana de Lucha Libre (EMLL), the world's oldest and Mexico's largest wrestling promotion. He made his debut at EMLL's main arena Arena Coliseo in February, 1956 in a Battle Royal that also included EMLL headliners Gory Guerrero, El Santo, Cavernario Galindo, Blue Demon and Black Shadow, a match that immediately established him as someone who Lutteroth saw potential in. In EMLL Mendoza struck up a friendship with Rene Guajardo and Karloff Lagarde out of the ring and a "partnership in crime" in the ring as the three became one of the most hated trio in lucha libre at the time. The three drew full houses all over Mexico, setting box office record after box office record as they faced tecnicos(good guys) such as El Santo, Rayo de Jalisco or Blue Demon. They also had a very financially successful feud with Los Espantos (Espanto I, Espanto II, and Espanto III) in what at the time was a rare rudo vs. rudo feud. Outside the ring Mendoza, Guajardo and Lagarde often spoke out on behalf of the wrestlers, demanding higher pay and better conditions, and since they were able to generate a lot of ticket sales EMLL officials listened to their demands.
