PROBLEM: Passage: Lennon first met Yoko Ono on 9 November 1966 at the Indica Gallery in London, where Ono was preparing her conceptual art exhibit. They were introduced by gallery owner John Dunbar. Lennon was intrigued by Ono's "Hammer A Nail": patrons hammered a nail into a wooden board, creating the art piece. Although the exhibition had not yet begun, Lennon wanted to hammer a nail into the clean board, but Ono stopped him. Dunbar asked her, "Don't you know who this is? He's a millionaire! He might buy it." Ono had supposedly not heard of the Beatles, but relented on condition that Lennon pay her five shillings, to which Lennon replied, "I'll give you an imaginary five shillings and hammer an imaginary nail in." Ono subsequently related that Lennon had taken a bite out of the apple on display in her work Apple, much to her fury.Ono began to telephone and visit Lennon at his home. When Cynthia asked him for an explanation, Lennon explained that Ono was only trying to obtain money for her "avant-garde bullshit". While his wife was on holiday in Greece in May 1968, Lennon invited Ono to visit. They spent the night recording what would become the Two Virgins album, after which, he said, they "made love at dawn". When Lennon's wife returned home she found Ono wearing her bathrobe and drinking tea with Lennon who simply said, "Oh, hi." Ono became pregnant in 1968 and miscarried a male child on 21 November 1968, a few weeks after Lennon's divorce from Cynthia was granted.Two years before the Beatles disbanded, Lennon and Ono began public protests against the Vietnam War. They were married in Gibraltar on 20 March 1969, and spent their honeymoon at the Hilton Amsterdam, campaigning with a week-long Bed-In for Peace. They planned another Bed-In in the United States but were denied entry, so they held one instead at the Queen Elizabeth Hotel in Montreal, where they recorded "Give Peace a Chance". They often combined advocacy with performance art, as in their "Bagism", first introduced during a Vienna press conference. Lennon detailed this period in the Beatles song "The Ballad of John and Yoko". Lennon changed his name by deed poll on 22 April 1969, adding "Ono" as a middle name. The brief ceremony took place on the roof of the Apple Corps building, where the Beatles had performed their rooftop concert three months earlier. Although he used the name John Ono Lennon thereafter, official documents referred to him as John Winston Ono Lennon, since he was not permitted to revoke a name given at birth. The couple settled at Tittenhurst Park at Sunninghill in Berkshire. After Ono was injured in a car accident, Lennon arranged for a king-size bed to be brought to the recording studio as he worked on the Beatles' last album, Abbey Road.Ono and Lennon moved to New York, to a flat on Bank Street, Greenwich Village. Looking for somewhere with better security, they relocated in 1973 to the more secure Dakota overlooking Central Park at 1 West 72nd Street. 
Question: What are the last names of the two individuals who spent the night recording what would become the Two Virgins album?

SOLUTION: Lennon.

PROBLEM: Passage: After thief Alex Cardo gets caught and betrayed by his partner in crime John while stealing an ancient Jian in Thailand, he soon finds himself imprisoned and beaten. One of the guards, Demon, is particularly upset by Alex's appearance and tortures him whenever he gets the opportunity. Alex finds one friend and mentor in the jailhouse, Master Sun, who teaches him a superior fighting style called "Iron Hand". When a "best of the best kumite" is to take place, Demon gets an invitation. Now Master Sun and Alex need to find a way to let Alex take part in the kumite, too.
The final fight pits Alex and Demon together.  At first, and for a long time, Demon has the upper hand in terms of strength and fighting ability.

PROBLEM: Passage: Aaliyah Dana Haughton (; January 16, 1979 – August 25, 2001) was an American singer, actress, and model. Born in Brooklyn, New York, and raised in Detroit, Michigan, she first gained recognition at the age of 10, when she appeared on the television show Star Search and performed in concert alongside Gladys Knight. At the age of 12, Aaliyah signed with Jive Records and her uncle Barry Hankerson's Blackground Records. Hankerson introduced her to R. Kelly, who became her mentor, as well as lead songwriter and producer of her debut album, Age Ain't Nothing but a Number. The album sold 3 million copies in the United States and was certified double platinum by the Recording Industry Association of America (RIAA). After facing allegations of an illegal marriage with Kelly, Aaliyah ended her contract with Jive and signed with Atlantic Records.
Aaliyah worked with record producers Timbaland and Missy Elliott for her second album, One in a Million, which sold 3 million copies in the United States and more than 8 million copies worldwide. In 2000, Aaliyah appeared in her first film, Romeo Must Die. She contributed to the film's soundtrack, which spawned the single "Try Again". The song topped the Billboard Hot 100 solely on airplay, making Aaliyah the first artist in Billboard history to achieve this goal. "Try Again" also earned Aaliyah a Grammy Award nomination for Best Female R&B Vocalist. After completing Romeo Must Die, Aaliyah filmed her role in Queen of the Damned, and released her self-titled third and final studio album in 2001.
On August 25, 2001, Aaliyah and eight others were killed in a plane crash in the Bahamas after filming the music video for the single "Rock the Boat". The pilot, Luis Morales III, was unlicensed at the time of the accident and toxicology tests revealed that he had traces of cocaine and alcohol in his system. Aaliyah's family later filed a wrongful death lawsuit against Blackhawk International Airways, which was settled out of court. Aaliyah's music continued to achieve commercial success with several posthumous releases, and has sold an estimated 24 to 32 million albums worldwide. She has been credited for helping redefine contemporary R&B, pop and hip hop, earning her the nicknames the "Princess of R&B" and "Queen of Urban Pop". Billboard lists her as the tenth most successful female R&B artist of the past 25 years, and the 27th most successful in history. 
Question: What is the last name of the person who ended her contract with Jive and signed with Atlantic Records?

SOLUTION:
Haughton.
