Problem: Background: Janet Damita Jo Jackson (born May 16, 1966) is an American singer, songwriter, dancer, and actress. Known for sonically innovative, socially conscious and sexually provocative records, and elaborate stage shows, she has been a prominent figure in popular culture for over thirty years. The youngest child of the Jackson family, she began her career with the variety television series The Jacksons in 1976 and went on to appear in other television shows throughout the 1970s and early 1980s, including Good Times and Fame. After signing a recording contract with A&M Records in 1982, she became a pop icon following the release of her third studio album Control (1986).
Context: Jackson began recording her ninth studio album, 20 Y.O., in 2005. She recorded with producers Dupri, Jam and Lewis for several months during the following year. The album's title was a reference to the two decades since the release of her breakthrough album Control, representing the album's "celebration of the joyful liberation and history-making musical style."  To promote the album, Jackson appeared in various magazines, and performed on the Today Show and Billboard Awards. Jackson's Us Weekly cover, revealing her slim figure after heavy media focus was placed on her fluctuations in weight, became the magazine's best-selling issue in history. 20 Y.O. was released in September 2006 and debuted at number two on the Billboard 200. The album received mixed reviews, with multiple critics chastising the production and involvement of Jermaine Dupri. Rolling Stone disagreed with the album's reference to Control, saying "If we were her, we wouldn't make the comparison."  Jackson's airplay and music channel blacklist remained persistent, massively affecting her chart performance and exposure. However, lead single "Call on Me", which featured rapper Nelly, peaked at number twenty-five on the Hot 100, number one on the Hot R&B/Hip-Hop Songs chart, and number six in the United Kingdom. The video for the album's second single, "So Excited", was directed by Joseph Kahn and portrayed Jackson's clothes disappearing through a complex dance routine.  20 Y.O. was certified platinum by the RIAA and sold 1.2 million worldwide, also receiving a Grammy nomination for Best Contemporary R&B Album. After the album's release, Dupri was condemned for his production and misguidance of the album, and subsequently was removed from his position at Virgin Records. Slant Magazine stated, "After promising a return to Janet's dance-pop origins, [Dupri] opted to aim for urban audiences, a colossal mistake that cost Dupri his job and, probably, Janet her deal with Virgin."  Jackson was ranked the seventh richest woman in the entertainment industry by Forbes, having amassed a fortune of over $150 million. In 2007, she starred opposite Tyler Perry as a psychotherapist in the film Why Did I Get Married?. It became her third consecutive film to open at number one at the box office, grossing $60 million in total. Jackson's performance was praised for its "soft authority", though also described as "charming, yet bland".
Question: Did she do any other type of work?
Answer: In 2007, she starred opposite Tyler Perry as a psychotherapist in the film Why Did I Get Married?.

Problem: Background: James Black was born in Hackensack, New Jersey on 1 May 1800. James' mother died when he was very young and he had difficulty getting along with his stepmother. Black ran away from home to Philadelphia, Pennsylvania at age 8 and was apprenticed to a silversmith. At age 18 he migrated westward and took jobs on the Ohio and Mississippi rivers.
Context: In 1830, Black made the famous Bowie knife for Jim Bowie who was already famous for knife-fighting from his 1827 sandbar duel. Bowie's killing of three assassins in Texas and his death at the Battle of the Alamo made him, and Black's knife, legends. After Bowie's death in 1836, Black did a brisk business selling his knives to pioneers bound for Texas. Everyone seemed to want "Jim Bowie's knife." Black forged his knives behind a leather curtain and kept his process a secret. Black's knives were known to be exceedingly tough yet flexible. Many claimed that Black had rediscovered the process to make Damascus steel.  James Black's wife Anne died in 1838; and in 1839, while Black was in bed from an illness, his father-in-law Shaw broke into Black's house and brutally attacked him with a club. Black's life was saved by the family dog; he survived, but his eyes were severely damaged by the attack. He went north to seek medical advice, where his eyes were further damaged by the inept ministrations of a Cincinnati, Ohio, physician. When Black returned to Arkansas he discovered that his father-in-law had sold his business and property, illegally, and disappeared with the cash.  Black lived on a local plantation for a couple of years until Dr. Isaac Newton Jones took him into his home. Black lived with the Jones family for the next 30 years. He attempted to pass on his knife-making secrets to Daniel Webster Jones, but unfortunately he could not remember the technique. Jones would later become Governor of Arkansas. James Black died on 22 June 1872 in Washington, Arkansas.  More skeptically, "...[T]here is no direct contemporary evidence to establish that James Black made a knife for James Bowie... The story rests solely on Black's claims made well after he had been adjudged mentally incompetent..." "...[T]he only time that [James Bowie] verifiably used a knife in a personal encounter was on the Sandbar in 1827..." "...[T]o this day there is no known knife bearing his name that is proven authentic, nor positively identified as the work of James Black. Neither is it proven beyond doubt that he even made a knife of any type!" Shifting the question (and the burden of proof) from people to knives, "...[T]he Black explanation remains the most logical way to understand this part of the Bowies' history."
Question: Why was he adjudged mentally incompetent?
Answer:
More skeptically, "...[T]here is no direct contemporary evidence to establish that James Black made a knife for James Bowie...
