[EX Q]: Passage: Sir Richard Starkey  (born 7 July 1940), known professionally as Ringo Starr, is an English musician, singer, songwriter and actor who gained worldwide fame as the drummer for the Beatles. He occasionally sang lead vocals with the group, usually for one song on each album, including "With a Little Help from My Friends", "Yellow Submarine", "Good Night", and their cover of "Act Naturally". He also wrote and sang the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying".
Starr was afflicted by life-threatening illnesses during childhood, and he fell behind in school as a result of prolonged hospitalisations. He briefly held a position with British Rail before securing an apprenticeship at a Liverpool equipment manufacturer. Soon afterwards, he became interested in the UK skiffle craze and developed a fervent admiration for the genre. In 1957, he co-founded his first band, the Eddie Clayton Skiffle Group, which earned several prestigious local bookings before the fad succumbed to American rock and roll by early 1958. When the Beatles formed in 1960, Starr was a member of another Liverpool group, Rory Storm and the Hurricanes. After achieving moderate success in the UK and Hamburg, he quit the Hurricanes and joined the Beatles in August 1962, replacing Pete Best.
Starr played key roles in the Beatles' films and appeared in numerous others. After the band's break-up in 1970, he released several successful singles including the US number-four hit "It Don't Come Easy", and number ones "Photograph" and "You're Sixteen". In 1972, he released his most successful UK single, "Back Off Boogaloo", which peaked at number two. He achieved commercial and critical success with his 1973 album Ringo, which was a top-ten release in both the UK and the US. He has featured in a number of documentaries and hosted television shows.  He also narrated the first two series of the children's television programme Thomas & Friends and portrayed "Mr Conductor" during the first season of the PBS children's television series Shining Time Station. Since 1989, he has toured with thirteen variations of Ringo Starr & His All-Starr Band.
Starr's musicianship has received praise from other drummers, including Phil Collins and Journey's Steve Smith. He was inducted into the Modern Drummer Hall of Fame in 1998. In 2011, Rolling Stone readers named Starr the fifth-greatest drummer of all time. Starr, who was previously inducted into the Rock and Roll Hall of Fame as a Beatle in 1988, was inducted for his solo career in 2015, making him one of 21 performers inducted more than once. He is the richest drummer in the world with a net worth of US$350 million. He was appointed a Knight Bachelor in the 2018 New Year Honours for services to music.

[EX Q]: Passage: 4 is the fourth solo studio album by American singer Beyoncé. It was released on June 24, 2011 by Parkwood Entertainment and Columbia Records. Following a career hiatus that reignited her creativity, Beyoncé was inspired to create a record with a basis in traditional rhythm and blues that stood apart from contemporary popular music. Her collaborations with songwriters and record producers The-Dream, Tricky Stewart and Shea Taylor produced a mellower tone, developing diverse vocal styles and influences from funk, hip hop, and soul music.
Severing professional ties with father and manager Mathew Knowles, Beyoncé eschewed the music of her previous releases in favor of an intimate, personal album. 4's lyrics emphasize monogamy, female empowerment and self-reflection, a result of Beyoncé considering a maturer message to contend artistic credibility. In May 2011, Beyoncé submitted seventy-two songs to Columbia Records for consideration, twelve of which appeared on the standard edition.
4 was promoted in mid-2011 by television performances and festival appearances, such as Beyoncé's headlining Glastonbury Festival set. The album received generally positive reviews by music critics; several publications included it on their year-end lists. It was her fourth consecutive album to debut at number one on the US Billboard 200, and it also reached number one in Brazil, France, Ireland, South Korea, Spain, Switzerland and the United Kingdom. 4 spawned the international singles "Run the World (Girls)", "Best Thing I Never Had", "Party", "Love on Top" and "Countdown". "Love on Top" won the Grammy Award for Best Traditional R&B Performance at the 55th annual ceremony. As of December 2015, 4 has sold 1.5 million copies in the United States. 
Question: What is the last name of the person who submitted seventy-two songs to Columbia Records for consideration?

Knowles.
