A question may be either a linguistic expression used to make a request for information, or else the request itself made by such an expression. This information may be provided with an answer.

Questions are normally put forward or asked using interrogative sentences. However they can also be formed by imperative sentences, which normally express commands: "Tell me what two plus two is"; conversely, some expressions, such as "Would you pass the salt?", have the grammatical form of questions but actually function as requests for action, not for answers, making them allofunctional. (A phrase such as this could, theoretically, also be viewed not merely as a request but as an observation of the other person's desire to comply with the request given.)

Questions have a number of uses. 'Raising a question' may guide the questioner along an avenue of research (see Socratic method). A rhetorical question is asked to make a point, and does not expect an answer (often the answer is implied or obvious). Pre-suppositional questions, such as "Have you stopped beating your wife?" may be used as a joke or to embarrass an audience, because any answer a person could give would imply more information than he was willing to affirm. Questions can also be titles of works of art and literature (e.g. Leo Tolstoy's short story How Much Land Does a Man Need? and the movie What About Bob?), or a scholarly monograph (e.g. Who Asked the First Question?). McKenzie lists 17 types of questions in his "Questioning Toolkit" and suggests that thinkers must orchestrate and combine these types in his article "Punchy Question Combinations". Examples of his question types include the irreverent question, the apparently irrelevant question, the hypothetical question and the unanswerable question. Questions can be infelicitous as well, based on incorrect and illogical premises (e.g. "Why do cats have green wings?").

System of a Down, also known by the acronym SOAD and often shortened to System, is a rock band from Southern California, formed in 1994. It consists of Serj Tankian (lead vocals, keyboards, rhythm guitar), Daron Malakian (guitar, vocals), Shavo Odadjian (bass, background vocals) and John Dolmayan (drums).

The band achieved commercial success with the release of five studio albums; from which three debuted at number one on the Billboard 200. System of a Down has been nominated for four Grammy Awards, and won the award in 2006 for Best Hard Rock Performance for the song "B.Y.O.B.". The group went on hiatus in August 2006, but reunited in November 2010, embarking on a worldwide tour in 2011.

Serj Tankian, Daron Malakian, and Shavo Odadjian all attended Rose and Alex Pilibos Armenian School while children, although because of their eight-year age difference they did not meet until 1992 while working on separate projects at the same recording studio. They formed a band named Soil with Tankian on vocals and keyboards, Malakian on vocals and guitar, Dave Hakopyan (who later played in The Apex Theory/Mt. Helium) on bass and Domingo "Dingo" Laranio on drums. The band hired Shavo Odadjian (another Rose and Alex Pilibos alumnus) as manager, although he eventually joined Soil as rhythm guitarist. After three years, only one live show, and one jam session recording, Hakopyan and Laranio quit the band, feeling that it was not going anywhere.

Nathaniel Marvin "Nat" Wolff (born December 17, 1994) is an American child actor, and singer-songwriter, composer, and keyboardist. He is the frontman of Nat & Alex Wolff. He is best known for his role as himself on the Nickelodeon series The Naked Brothers Band.

Wolff was born in Los Angeles, California to actress Polly Draper (of TV's Thirtysomething) and jazz pianist Michael Wolff. He is the older brother of actor/musician and composer Alex Wolff. His maternal grandfather is venture capitalist William Henry Draper III. Wolff's father is Jewish and his mother is a Quaker. He says that in his spare time he likes to play basketball, write music, and play with the family's dog, E.T.

When Wolff was very young, he put signs on his bedroom door stating: "I want to be a child actor!" At first, his mother refused because she didn't want her children exposed to superstardom because they were very young. As a result, Draper decided to appease Nat by filming his own sitcom called, Don't Eat Off My Plate.

Curtis James Jackson III (born July 6, 1975), better known by his stage name 50 Cent, is an American rapper, entrepreneur, investor, record producer, and actor. He rose to fame with the release of his albums Get Rich or Die Tryin' (2003) and The Massacre (2005). His album Get Rich or Die Tryin' has been certified eight times platinum by the RIAA.

Born in the South Jamaica of Queens, New York City, Jackson began drug dealing at the age of twelve during the 1980s crack epidemic. After leaving drug dealing to pursue a rap career, he was shot at and struck by nine bullets during an incident in 2000. After releasing his album Guess Who's Back? in 2002, Jackson was discovered by rapper Eminem and signed to Interscope Records. With the help of Eminem and Dr. Dre, who produced his first major commercial successes, Jackson became one of the world's highest selling rappers. In 2003, he founded the record label G-Unit Records, which signed several successful rappers such as Young Buck, Lloyd Banks, and Tony Yayo.
