input: On January 4, 2000, Cuban purchased a majority stake in the NBA's Dallas Mavericks for $285 million from H. Ross Perot, Jr. In the 20 years before Cuban bought the team, the Mavericks won only 40% of their games, and a playoff record of 21-32. In the 10 years following, the team won 69 percent of their regular season games and reached the playoffs in each of those seasons except for one. The Mavericks' playoff record with Cuban is 49 wins and 57 losses, including their first trip to the NBA Finals in 2006, where they lost to the Miami Heat. On June 12, 2011, the Mavericks defeated the Heat to win the NBA Finals. Historically, NBA team owners publicly play more passive roles and watch basketball games from skyboxes; Cuban sits alongside fans while donning team jerseys. Cuban travels in his private airplane--a Gulfstream V--to attend road games. In May 2010, H. Ross Perot, Jr., who retained 5% ownership, filed a lawsuit against Cuban, alleging the franchise was insolvent or in imminent danger of insolvency. In June 2010, Cuban responded in a court filing maintaining Perot is wrongly seeking money to offset some $100 million in losses on the Victory Park real estate development. The lawsuit was dismissed in 2011, due in part to Cuban asserting proper management of the team due to its recent victory in the 2011 NBA Finals. In 2014, the 5th Circuit Court affirmed that decision on appeal. Following his initial defeat, Perot attempted to shut out Mavericks fans from use of the parking lots he controlled near the American Airlines Center. In January 2018, Cuban announced the Mavericks would be accepting Bitcoin as payment for tickets in the following season.

Answer this question "How else was he involved?"

Problem: Background: Madalyn Murray O'Hair (nee Mays; April 13, 1919 - September 29, 1995), was an American activist, founder of American Atheists, and the organization's president from 1963 to 1986. She created the first issues of American Atheist Magazine. O'Hair is best known for the Murray v. Curlett lawsuit, which led to a landmark Supreme Court ruling ending official Bible-reading in American public schools in 1963. That case came just one year after the Supreme Court prohibited officially sponsored prayer in schools in Engel v. Vitale.
Context: Murray filed a lawsuit against the Baltimore City Public School System (Murray v. Curlett) in 1960 in which she asserted that it was unconstitutional for her son William to be required to participate in Bible readings at Baltimore public schools. In this litigation, she stated that her son's refusal to partake in the Bible readings had resulted in bullying being directed against him by classmates and that administrators condoned it. After consolidation with Abington School District v. Schempp, the lawsuit reached the Supreme Court of the United States in 1963. The Court voted 8-1 in Schempp's favor, which effectively banned mandatory Bible verse recitation at public schools in the United States. Prayer in schools other than Bible-readings had already been ended in 1962 by the Court's ruling in Engel v. Vitale. O'Hair filed a lawsuit with the National Aeronautics and Space Administration (NASA) in regard to the Apollo 8 Genesis reading. The case was rejected by the U.S. Supreme Court for lack of jurisdiction. The impact of the suit was limited: Although NASA asked Buzz Aldrin to refrain from quoting the Bible in the Apollo 11 mission, he was allowed to conduct the first Communion service in space. O'Hair appeared on The Phil Donahue Show several times, including the first episode in 1967, following which Phil Donahue said O'Hair was unpleasant and had mocked him off camera for being a Catholic, although after O'Hair's death, Donahue described her message of atheism as "very important". She appeared on the show again in March 1970 to debate Preacher Bob Harrington, "The Chaplain of Bourbon Street". O'Hair endorsed Jimmy Carter in the 1976 presidential election because of Carter's opposition to mandatory school prayer, his support for sex education in public schools, and his stance on ecological matters.
Question: did she support any other causes?
Answer: endorsed Jimmy Carter in the 1976 presidential election because of Carter's opposition to mandatory school prayer, his support for sex education

Question: Kerli Koiv was born in Elva on February 7, 1987. Her mother, Piret Koiv, was a social worker, and her father, Toivo Koiv, was an auto mechanic. Her parents separated when she was 16. Kerli has stated that when she wrote "Supergirl"--a song about domestic violence written for Utopia--she "put [herself] in [her] mother's body, and said things that [she] wished that [her mother] would've said to her dad when [she] was little".

On 5 November 2015, it was revealed that Kerli composed a song for Eesti Laul 2016, Estonia's national selection for the Eurovision Song Contest 2016. In 2015, Kerli left Los Angeles and returned to Estonia, where she spent nine months with no running water and only her music-making gear to keep her company, where she produced her first independent album. Her single "Feral Hearts" was released digitally worldwide on 19 February 2016. The music video for "Feral Hearts" was released the following week on February 25. "Blossom", the second single from her second studio album, followed with a video on 28 April and the song's release on iTunes the next day. On 26 June, Kerli released the song "Racing Time". She explained that it was one of three songs written for the 2016 film Alice Through the Looking Glass. She had previously contributed to the Almost Alice concept album for the 2010 film Alice in Wonderland. However, the songs were not included on the latest movie's soundtrack. On 27 July, she released the third single from her upcoming sophomore studio album, "Diamond Hard", along with its music video. On April 22, 2016, Kerli was featured as a vocalist and co-wrote a song on British artist Katy B's 'Honey' album (Rinse/Virgin EMI). She co-wrote and sang the hook on "I Wanna Be." On 8 November 2016, it was revealed that Kerli would compete in Eesti Laul 2017, with the song "Spirit Animal". She reached the final and finished second in the competition. She was later announced to be representing Estonia in the OGAE Second Chance Contest 2017 with "Spirit Animal", held in Warsaw.
