Problem: Background: Elizabeth of York (11 February 1466 - 11 February 1503) was queen consort of England from 1486 until her death. As the wife of Henry VII, she was the first Tudor queen. She was the daughter of Edward IV and niece of Richard III, and she married the king following Henry's victory at the Battle of Bosworth which started the last phase of the Wars of the Roses. She was the mother of King Henry VIII.
Context: As the eldest daughter of Edward IV with no surviving brothers, Elizabeth of York had a strong claim to the throne in her own right, but she did not assume the throne as queen regnant. Such a precedent would not truly come to England for another 67 years, when her granddaughter, Mary I, acceded to the throne. Though initially reluctant to keep his promise Henry VII acknowledged the necessity of marrying Elizabeth of York to ensure the stability of his rule and weaken the claims of other surviving members of the House of York, but he ruled in his own right and claimed the throne by right of conquest and not by his marriage to the heir of the House of York. He had no intention of sharing power. He consequently chose to be crowned on 30 October 1485 before his marriage.  Henry VII had the Titulus Regius repealed, thereby legitimising the children of Edward IV, and acknowledged Edward V as his predecessor. After procuring papal dispensation, Cardinal Bourchier, Archbishop of Canterbury, officiated at the wedding of Henry VII and Elizabeth of York on 18 January 1486 in Westminster Abbey. Their first son, Arthur, was born on 20 September 1486. Elizabeth of York was crowned queen on 25 November 1487. Following her coronation, she gave birth to seven more children, but only four survived infancy: Arthur, Margaret, Henry and Mary.  Despite being a political arrangement at first, the marriage proved successful and both partners appear to have grown to love each other. Elizabeth of York did not exercise much political influence as queen due to her strong-minded mother-in-law Lady Margaret Beaufort, but she was reported to be gentle, kind, and generous to her relations, servants, and benefactors. When not at official gatherings, she lived a quiet life largely away from politics with three of her children at Eltham Palace. Elizabeth of York enjoyed music and dancing as well as dicing. She also kept greyhounds.  On 14 November 1501, Elizabeth of York's 15-year-old son Arthur married Catherine of Aragon, daughter of King Ferdinand II of Aragon and Queen Isabella I of Castile. The pair were sent to Ludlow Castle, the traditional residence of the prince of Wales. Arthur died in April 1502. The news of Arthur's death caused Henry VII to break down in grief, as much in fear for his dynasty as in mourning for his son. Elizabeth comforted him, telling him that he was the only child of his mother but had survived to become king, that God had left him with a son and two daughters, and that they were both young enough to have more children.
Question: who was she the wife of?
Answer: Henry VII

Problem: Background: Erykah Badu was born Erica Abi Wright in Dallas, Texas. Her mother raised her, her brother Eevin, and her sister Nayrok alone after separating from their father, William Wright Jr. To provide for her family, the children's maternal and paternal grandmothers often helped look after them. Badu had her first taste of show business at the age of four, singing and dancing at the Dallas Theater Center and The Black Academy of Arts and Letters (TBAAL) under the guidance of her godmother, Gwen Hargrove, and uncle TBAAL founder Curtis King.
Context: In May 2013, Badu announced she was writing her next project, but not placing a time constraint on it. In July 2014, Badu revealed she was still working on the album and had been recording in April in Africa where she was "laying down drum tracks". Badu also said that prior to her trip to Africa she would have meetings with her record label to set a deadline for the album. Later that year Badu expanded on the album, stating she was working with producer Flying Lotus, who she met via MySpace years ago; they later met in L.A. at guitarist Steve Wilson's house. In 2015 Badu appeared on "Rememory", a song from Donnie Trumpet & The Social Experiment's album Surf. In July 2015, Badu released a free mixtape of her favorite recordings, describing the set as "carefully and lovingly selected high frequency tones for the soul." The mixtape features mostly vintage funk, soul and jazz songs. On March 26, 2015, Erykah Badu performed at The Bomb Factory in her hometown, Dallas, Texas, for the Deep Ellum venue's grand opening. The sold-out show also featured fellow Dallas native, singer-songwriter Sarah Jaffe.  In early October, Badu released a remix of Drake's single "Hotline Bling", and later released a mixtape, But You Caint Use My Phone, on November 27, 2015, making it available for digital download and streaming exclusively through Apple Music. After one week of exclusive release on iTunes, But You Caint Use My Phone was released to other digital retailers and streaming services on December 4, 2015. The mixtape was released without the knowledge of her label Universal, due to Badu sending the record straight to iTunes. It also marked Badu's first release under her own record label, Control Freaq. But You Caint Use My Phone received generally positive reviews from critics and debuted at number 14 on the Billboard 200, selling 35,000 equivalent album units in its first week. Badu also hosted the 2015, 2016 and the 2017 Soul Train Music Awards.  Badu held her annual "Still Boomin'" sold-out birthday bash concert at The Bomb Factory on February 26, 2016, marking her second performance at the venue since its grand opening 11 months earlier. The event was hosted by Badu's close friend Dave Chappelle and featured a surprise appearance by Outkast frontman Andre 3000. Badu enlisted Dallas local hip hop acts -topic, Zach Witness, and Cameron McCloud as her supporting acts.
