Problem: Background: Sherlock Holmes () is a fictional private detective created by British author Sir Arthur Conan Doyle. Referring to himself as a "consulting detective" in the stories, Holmes is known for his proficiency with observation, forensic science, and logical reasoning that borders on the fantastic, which he employs when investigating cases for a wide variety of clients, including Scotland Yard. First appearing in print in 1887 (in A Study in Scarlet), the character's popularity became widespread with the first series of short stories in The Strand Magazine, beginning with "A Scandal in Bohemia" in 1891; additional tales appeared from then until 1927, eventually totalling four novels and 56 short stories. All but one are set in the Victorian or Edwardian eras, between about 1880 and 1914.
Context: Details about Sherlock Holmes's life, except for the adventures in the books, are scarce in Conan Doyle's original stories. Nevertheless, mentions of his early life and extended family paint a loose biographical picture of the detective.  An estimate of Holmes's age in "His Last Bow" places his year of birth at 1854; the story, set in August 1914, describes him as sixty years of age. His parents are not mentioned in the stories, although Holmes mentions that his "ancestors" were "country squires". In "The Adventure of the Greek Interpreter", he claims that his grandmother was sister to the French artist Vernet, without further clarifying whether this was Claude Joseph, Carle, or Horace Vernet. Holmes's brother Mycroft, seven years his senior, is a government official who appears in "The Adventure of the Greek Interpreter", "The Final Problem", and "The Adventure of the Bruce-Partington Plans" and is mentioned in "The Adventure of the Empty House". Mycroft has a unique civil service position as a kind of human database for all aspects of government policy. He lacks Sherlock's interest in physical investigation, however, preferring to spend his time at the Diogenes Club.  Holmes says that he first developed his methods of deduction as an undergraduate; his earliest cases, which he pursued as an amateur, came from fellow university students. A meeting with a classmate's father led him to adopt detection as a profession, and he spent six years after university as a consultant before financial difficulties led him to accept John H. Watson as a fellow lodger in 1881 (when the first published story, A Study in Scarlet, begins).  The two take lodgings at 221B Baker Street, London, an apartment at the upper (north) end of the street, up seventeen steps.
Question: Did he only have the one brother?

Problem: Background: Mel Brooks (born Melvin Kaminsky; June 28, 1926) is an American actor, writer, producer, director, comedian, and composer. He is known as a creator of broad film farces and comic parodies. Brooks began his career as a comic and a writer for the early TV variety show Your Show of Shows. He created, with Buck Henry, the hit television comedy series Get Smart, which ran from 1965 to 1970.
Context: For several years, Brooks had been toying with a bizarre and unconventional idea about a musical comedy of Adolf Hitler. Brooks explored the idea as a novel and a play before finally writing a script. Eventually, he was able to find two producers to fund the show, Joseph E. Levine and Sidney Glazier, and made his first feature film, The Producers, in 1967.  The Producers was so brazen in its satire that major studios would not touch it, nor would many exhibitors. Brooks finally found an independent distributor who released it as an art film, a specialized attraction. In 1968, Brooks received an Oscar for Best Original Screenplay for the film, beating such writers as Stanley Kubrick and John Cassavetes. The Producers became a smash underground hit, first on the nationwide college circuit, then in revivals and on home video. Brooks later turned it into a musical, which became hugely successful on Broadway, receiving an unprecedented twelve Tony awards.  With the moderate financial success of the film The Producers, Glazier financed Brooks' next film in 1970, The Twelve Chairs. Loosely based on a Russian 1928 novel The Twelve Chairs by Ilf and Petrov about greedy materialism in post-revolutionary Russia, the film stars Ron Moody, Frank Langella, and Dom DeLuise as three men individually searching for a fortune in diamonds hidden in a set of 12 antique chairs. Brooks makes a cameo appearance as an alcoholic ex-serf who "yearns for the regular beatings of yesteryear." The film was shot in Yugoslavia with a budget of $1.5 million. The film received poor reviews and was not financially successful.
Question: What was that film about?
Answer: Loosely based on a Russian 1928 novel The Twelve Chairs by Ilf and Petrov about greedy materialism in post-revolutionary Russia,

Problem: Background: Dennis Coles (born May 9, 1970), better known by his stage name Ghostface Killah, is an American rapper and member of the Wu-Tang Clan. After the group achieved breakthrough success in the aftermath of Enter the Wu-Tang (36 Chambers), the members went on to pursue solo careers to varying levels of success. Ghostface Killah debuted his solo-career with Ironman in 1996, which was well received by music critics. He has continued his success over the following years with critically acclaimed albums such as Supreme Clientele (2000) and Fishscale (2006).
Context: A roommate of Wu-Tang founder RZA, Ghostface helped bring together the other seven members. In 1995, Ghostface guest-starred extensively on fellow Clan member Raekwon's debut album, Only Built 4 Cuban Linx..., appearing on almost every song and receiving nearly equal billing. He also contributed songs to the Sunset Park and Don't Be a Menace to South Central While Drinking Your Juice in the Hood soundtracks, which would be included on his first solo LP, Ironman, in 1996. The album, which debuted at #2 on the Billboard 200, had a more pronounced soul influence (particularly 1970s soul) than previous Wu-Tang releases, and Ghostface's future albums would continue to feature this stylistic trait.  In 2000, he released his second studio album Supreme Clientele. The album was well received by critics and peaked #7 on the Billboard 200. It included "Apollo Kids", a popular single which featured Raekwon and had a sample of "Cool Breeze" by Solomon Burke. "Cherchez LaGhost", another single off the album, became a minor club hit. Supreme Clientele would be a turning point in RZA's influence on his sound, as only six songs are produced by the RZA, compared to Ironman, its predecessor where every song but one is produced by him. Though he contributed fewer beats to the project, RZA personally oversaw the mixing and production of the album as a whole, contributing to Supreme Clientele's unified sound.  Ghostface wasted little time in recording his next album, the heavily R&B-influenced Bulletproof Wallets, released a year after Supreme Clientele. Its feature single, "Never Be the Same Again", featured Carl Thomas and Raekwon. He had another minor club hit with "Flowers", which featured guest vocals from fellow Wu-Tang members Method Man and Raekwon, and a popular single "Ghost Showers" which featured Madame Majestic, who also sung on the popular Wu-Tang track "Gravel Pit".
Question: did he contribute songs to any other album?
Answer:
Only Built 4 Cuban Linx..., appearing on almost every song and receiving nearly equal billing.
