Problem: Background: Brown was born on July 28, 1891, in Holgate, Ohio, near Toledo, into a large family largely of Welsh descent. He spent most of his childhood in Toledo. In 1902, at the age of ten, he joined a troupe of circus tumblers known as the Five Marvelous Ashtons, who toured the country on both the circus and vaudeville circuits. Later he became a professional baseball player.
Context: In late 1928, Brown began making films, starting the next year with Warner Bros.. He quickly became a favorite with child audiences, and shot to stardom after appearing in the first all-color all-talking musical comedy On with the Show (1929). He starred in a number of lavish Technicolor Warner Brothers musical comedies including: Sally (1929), Hold Everything (1930), Song of the West (1930), and Going Wild (1930). By 1931, Joe E. Brown had become such a star that his name was billed above the title in the films in which he appeared.  He appeared in Fireman, Save My Child (1932), a comedy in which he played a member of the St. Louis Cardinals, and in Elmer, the Great (1933) with Patricia Ellis and Claire Dodd and Alibi Ike (1935) with Olivia de Havilland, in both of which he portrayed ballplayers with the Chicago Cubs.  In 1933 he starred in Son of a Sailor with Jean Muir and Thelma Todd. In 1934, Brown starred in A Very Honorable Guy with Alice White and Robert Barrat, in The Circus Clown again with Patricia Ellis and with Dorothy Burgess, and with Maxine Doyle in Six-Day Bike Rider.  Brown was one of the few vaudeville comedians to appear in a Shakespeare film; he played Francis Flute in the Max Reinhardt/William Dieterle film version of Shakespeare's A Midsummer Night's Dream (1935) and was highly praised for his performance. He starred in Polo Joe (1936) with Carol Hughes and Richard "Skeets" Gallagher, and in Sons o' Guns. In 1933 and 1936, he became one of the top ten earners in films. He was sufficiently well known internationally by this point to be depicted in comic strips in the British comic Film Fun for twenty years from 1933.  He left Warner Brothers to work for producer David L. Loew, starring in When's Your Birthday? (1937). In 1938, he starred in The Gladiator, a loose film adaptation of Philip Gordon Wylie's 1930 novel Gladiator that influenced the creation of Superman. He gradually switched to making "B" pictures.

Problem: Background: Opeth is a Swedish heavy metal band from Stockholm, formed in 1989. The group has been through several personnel changes, but lead vocalist, guitarist and songwriter Mikael Akerfeldt has remained Opeth's primary driving force throughout the years. Opeth has consistently incorporated progressive, folk, blues, classical and jazz influences into its usually lengthy compositions, as well as strong influences from death metal, especially in their early works. Many songs include acoustic guitar passages and strong dynamic shifts, as well as both death growls and clean vocals.
Context: Opeth was formed as a death metal band in 1989 in Stockholm, Sweden, by lead vocalist David Isberg. Isberg asked former Eruption band member Mikael Akerfeldt (just 16 years old at the time) to join Opeth as a bassist. When Akerfeldt showed up to practice on the day after Isberg invited him, it became clear that Isberg had not told the band members, including the band's current bassist, that Akerfeldt would be joining. An ensuing argument led to all members but Isberg and Akerfeldt leaving to form a new project. The band name was derived from the word "Opet", taken from the Wilbur Smith novel The Sunbird. In this novel, Opet is the name of a fictional Phoenician city in South Africa translated as "City of the Moon".  Isberg and Akerfeldt recruited drummer Anders Nordin, bassist Nick Doring, and guitarist Andreas Dimeo. Unsatisfied with Opeth's slow progress, Doring and Dimeo left the band after their first performance, and were replaced by guitarist Kim Pettersson and bassist Johan De Farfalla. After the next show, De Farfalla left Opeth to spend time with his girlfriend in Germany, and was initially replaced by Mattias Ander, before Akerfeldt's friend Peter Lindgren took on the role of bassist. Rhythm guitarist Kim Pettersson left following the band's next performance, and Lindgren switched to guitar, with the role of bassist falling to Stefan Guteklint. The following year, David Isberg left the band citing "creative differences".  Following Isberg's departure, Akerfeldt took over vocal duties and he, Lindgren, and Nordin spent the next year writing and rehearsing new material. The group began to rely less on the blast beats and aggression typical of death metal, and incorporated acoustic guitars and guitar harmonies into their music; developing the core sound of Opeth. Bassist Guteklint was dismissed by the band after they signed their first record deal with Candlelight Records in 1994. Opeth initially employed former member De Farfalla as a session bassist for their demo recordings, and he went on to join on a full-time basis following the release of Opeth's debut album, "Orchid", in 1995.
Question: What is Formation?
Answer: 

Problem: Background: Peale was born in 1741 in Chester, Queen Anne's County, Maryland, the son of Charles Peale and his wife Margaret. He had a younger brother, James Peale (1749-1831). Charles became an apprentice to a saddle maker when he was thirteen years old. Upon reaching maturity, he opened his own saddle shop; however, when his Loyalist creditors discovered he had joined the Sons of Liberty, they conspired to bankrupt his business.
Context: Peale's enthusiasm for the nascent national government brought him to the capital, Philadelphia, in 1776, where he painted portraits of American notables and visitors from overseas. His estate, which is on the campus of La Salle University in Philadelphia, can still be visited. He also raised troops for the War of Independence and eventually gained the rank of captain in the Pennsylvania militia by 1776, having participated in several battles. While in the field, he continued to paint, doing miniature portraits of various officers in the Continental Army. He produced enlarged versions of these in later years. He served in the Pennsylvania state assembly in 1779-1780, after which he returned to painting full-time.  Peale was quite prolific as an artist. While he did portraits of scores of historic figures (such as James Varnum, Benjamin Franklin, John Hancock, Thomas Jefferson, and Alexander Hamilton), he is probably best known for his portraits of George Washington. The first time Washington sat for a portrait was with Peale in 1772, and they had six other sittings; using these seven as models, Peale produced altogether close to 60 portraits of Washington. In January 2005, a full-length portrait of Washington at Princeton from 1779 sold for $21.3 million, setting a record for the highest price paid for an American portrait.  One of his most celebrated paintings is The Staircase Group (1795), a double portrait of his sons Raphaelle and Titian, painted in the trompe l'oeil style. It is in the collection of the Philadelphia Museum of Art.
Question: Who was the staircase group?
Answer:
a double portrait of his sons Raphaelle and Titian,
