Problem: Background: Canby was born in Piatt's Landing, Kentucky, to Israel T. and Elizabeth (Piatt) Canby. He attended Wabash College, but transferred to the United States Military Academy, from which he graduated in 1839. He was commissioned a second lieutenant in the 2nd U.S. Infantry and served as the regimental adjutant. Although often referred to as Edward Canby, a biographer has suggested that he was known as "Richard" during childhood and to some friends for most of his life.
Context: During his early career, Canby served in the Second Seminole War in Florida and saw combat during the Mexican-American War, where he received three brevet promotions, including to major for Contreras and Churubusco, and lieutenant colonel for Belen Gates. He also served at various posts, including Upstate New York and in the adjutant general's office in California from 1849 until 1851, covering the period of the territory's transition to statehood.  Against his wishes, he was assigned to what was supposed to be the civilian post of custodian of the California Archives from March 1850 until he left California in April 1851. The Archives included records of Spanish and Mexican governments in California, as well as Mission records and land titles. Evidently, Canby had some knowledge of the Spanish language, which was extremely useful as the government was trying to unravel land titles. (The Filson Historical Society in Louisville, Kentucky holds what appears to be a document written in Canby's hand in Spanish, in which he identifies himself as "Edwardo  [sic] Ricardo S. Canby.")  Canby served in Wyoming and Utah (then both part of the Utah Territory) during the Utah War (1857-1858). During this period, he served on the panel of judges for the court martial of Captain Henry Hopkins Sibley. Sibley was acquitted. Subsequently, Canby wrote an endorsement for a teepee-like army tent which Sibley had adapted from the American Indian style.  Both officers were later assigned to New Mexico, where in 1860 Canby coordinated a campaign against the Navajo, commanding Sibley in a futile attempt to capture and punish Navajo for "depredations" against the livestock of settlers. The campaign ended in frustration, with Canby and Sibley rarely sighting Navajo raiders. Usually they saw the Navajo at a distance and never got close to them.
Question: Did Canby fight any other Native Americans?
Answer: The campaign ended in frustration, with Canby and Sibley rarely sighting Navajo raiders.

Background: Stanley Kirk Burrell (born March 30, 1962), better known by his stage name MC Hammer (or simply Hammer), is an American hip hop recording artist, dancer, record producer and entrepreneur. He had his greatest commercial success and popularity from the late 1980s, until the early 1990s. Remembered for his rapid rise to fame, Hammer is known for hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album.
Context: Before Hammer's successful music career (with his mainstream popularity lasting approximately between 1988 and 1998) and his "rags-to-riches-to-rags-and-back saga", Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as K.B. and then eventually M.C. Hammer once it was produced), was later released on Gibson's album Change of Heart (1988). This was Contemporary Christian music's first rap hit ever. Burrell also produced "Son of the King" at that time, releasing it on his debut album. "Son of the King" showed up on Hammer's debut album Feel My Power (1987), as well as the re-released version Let's Get It Started (1988).  With exception to later remixes of early releases, Hammer produced and recorded many rap songs that were never made public, yet are now available on the Internet. Via his record labels such as Bust It Records, Oaktown Records and FullBlast, Hammer has introduced, signed and produced new talent including Oaktown's 3.5.7, Ho Frat Hoo!, the vocal quintet Special Generation, Analise, James Greer, One Cause One Effect, B Angie B, The Stooge Playaz, DASIT (as seen on ego trip's The (White) Rapper Show), Teabag, Common Unity, Geeman and Pleasure Ellis; both collaborating with him and producing music of their own during his career.  At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.
Question: What kicked off his career?
Answer:
Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys.
