Problem: Background: ZZ Top is an American rock band formed in 1969 in Houston, Texas. The band has, since 1970, consisted of bassist and lead vocalist Dusty Hill, guitarist and lead vocalist Billy Gibbons (the band's leader, main lyricist and musical arranger), and drummer Frank Beard. "As genuine roots musicians, they have few peers", according to former musician, critic and collector Michael "Cub" Koda. "Gibbons is one of America's finest blues guitarists working in the arena rock idiom [...] while Hill and Beard provide the ultimate rhythm section support."
Context: The original line-up was formed in Houston and consisted of Gibbons, organist Lanier Greig (died February 2013) and drummer Dan Mitchell. The name of the band was Gibbons' idea. The band had a little apartment covered with concert posters and he noticed that many performers' names utilized initials. Gibbons particularly noticed B.B. King and Z.Z. Hill and thought of combining the two into "ZZ King", but considered it too similar to the original name. He then figured that "king is going at the top" which brought him to "ZZ Top". ZZ Top was managed by Bill Ham, a Waxahachie, Texas native who had befriended Gibbons a year earlier. They released their first single, "Salt Lick", in 1969, and the B-side contained the song "Miller's Farm". Both songs were credited to Gibbons. Immediately after the recording of "Salt Lick", Greig was replaced by bassist Billy Ethridge, a band-mate of Stevie Ray Vaughan, and Mitchell was replaced by Frank Beard of the American Blues. Due to lack of interest from U.S. record companies, ZZ Top accepted a record deal from London Records. Unwilling to sign a recording contract, Ethridge quit the band and Dusty Hill was selected as his replacement. After Hill moved from Dallas to Houston, ZZ Top signed with London in 1970. They performed their first concert together at the Knights of Columbus Hall in Beaumont on February 10. In addition to assuming the role as the band's leader, Gibbons became the main lyricist and musical arranger. With the assistance of Ham and engineer Robin Hood Brians, ZZ Top's First Album (1971) was released and exhibited the band's humour, with "barrelhouse" rhythms, distorted guitars, double entendres, and innuendo. The music and songs reflected ZZ Top's blues influences. Following their debut album, the band released Rio Grande Mud (1972), which failed commercially and the promotional tour consisted of mostly empty auditoriums.

Problem: Background: Osceola was named Billy Powell at birth in 1804 in the Creek village of Talisi. now known as Tallassee, Alabama, in current Elmore County. "The people in the town of Tallassee...were mixed-blood Native American/English/Irish/Scottish, and some were black. Billy was all of these."
Context: After Osceola's death, army doctor Frederick Weedon persuaded the Seminole to allow him to make a death mask of Osceola, this being a European-American custom at the time for prominent people. Later he removed Osceola's head and embalmed it. For some time, Weedon kept the head and a number of personal objects Osceola had given him. Later, Weedon gave the head to his son-in-law Daniel Whitehurst. In 1843, Whitehurst sent the head to Valentine Mott, a New York physician. Mott placed it in his collection at the Surgical and Pathological Museum. It was presumably lost when a fire destroyed the museum in 1866. Some of Osceola's belongings are still held by the Weedon family, while others have disappeared. Captain Pitcairn Morrison sent the death mask and some other objects collected by Weedon to an army officer in Washington. By 1885, the death mask and some of Osceola's belongings had arrived in the anthropology collection of the Smithsonian Institution, where they are still held. In 1966, Miami businessman Otis W. Shriver claimed he had dug up Osceola's grave and put his bones into a bank vault to rebury them at a tourist site at the Rainbow Springs. Shriver traveled around the state in 1967 to gather support for his project. Archaeologists later proved that Shriver had dug up animal remains; Osceola's body was still in its coffin. In 1979 the Seminole Nation of Oklahoma bought Osceola's bandolier and other personal items from a Sotheby's auction. Because of the chief's significance, over time some people have created forgeries of Osceola's belongings. Rumors persist that his embalmed head has been found in various locations.
Question: What else was of importance?
Answer: Pitcairn Morrison sent the death mask and some other objects collected by Weedon to an army officer in Washington.

Problem: Background: Al-Awlaki was born in Las Cruces, New Mexico, in 1971 to parents from Yemen, while his father, Nasser al-Awlaki, was doing graduate work at U.S. universities. His father was a Fulbright Scholar who earned a master's degree in agricultural economics at New Mexico State University in 1971, received a doctorate at the University of Nebraska, and worked at the University of Minnesota from 1975 to 1977. Nasser al-Awlaki served as Agriculture Minister in Ali Abdullah Saleh's government. He was also President of Sana'a University.
Context: In July 2010, al-Awlaki's father, Nasser al-Awlaki, contacted the Center for Constitutional Rights and the American Civil Liberties Union to represent his son in a lawsuit that sought to remove Anwar from the targeted killing list. ACLU's Jameel Jaffer said: the United States is not at war in Yemen, and the government doesn't have a blank check to kill terrorism suspects wherever they are in the world. Among the arguments we'll be making is that, outside actual war zones, the authority to use lethal force is narrowly circumscribed, and preserving the rule of law depends on keeping this authority narrow. Lawyers for Specially Designated Global Terrorists must obtain a special license from the US Treasury Department before they can represent their clients in court. The lawyers were granted the license on August 4, 2010. On August 30, 2010, the groups filed a "targeted killing" lawsuit, naming President Obama, CIA Director Leon Panetta, and Secretary of Defense Robert Gates as defendants. They sought an injunction preventing the targeted killing of al-Awlaki, and also sought to require the government to disclose the standards under which US citizens may be "targeted for death". Judge John D. Bates dismissed the lawsuit in an 83-page ruling, holding that the father did not have legal standing to bring the lawsuit, and that his claims were judicially unreviewable under the political question doctrine inasmuch as he was questioning a decision that the US Constitution committed to the political branches. On May 5, 2011, the US tried but failed to kill al-Awlaki by firing a missile from an unmanned drone at a car in Yemen. A Yemeni security official said that two al-Qaeda operatives in the car died.
