Problem: Background: Ronald Shannon Jackson (January 12, 1940 - October 19, 2013) was an American jazz drummer and composer from Fort Worth, Texas. A pioneer of avant-garde jazz, free funk, and jazz fusion, he appeared on over 50 albums as a bandleader, sideman, arranger, and producer. Jackson and bassist Sirone are the only musicians to have performed and recorded with the three prime shapers of free jazz: pianist Cecil Taylor, and saxophonists Ornette Coleman and Albert Ayler.
Context: Once in New York, Jackson performed with many jazz musicians, including Charles Mingus, Betty Carter, Jackie McLean, Joe Henderson, Kenny Dorham, McCoy Tyner, Stanley Turrentine, and others. Whenever he would ask Charles Mingus to consider him for his group, Mingus used to push him "rudely out of his way". After Jackson sat in with pianist Toshiko Akiyoshi, he heard loud clapping behind him. It was Mingus, who asked him to play with his band.  In 1966 Jackson recorded drums for saxophonist Charles Tyler's release, Charles Tyler Ensemble. Between 1966 and 1967, he played with saxophonist Albert Ayler and is featured on At Slug's Saloon, Vol. 1 & 2. He is also on disks 3 and 4 of Ayler's Holy Ghost: Rare & Unissued Records (1962-70). Jackson said Ayler was "the first (leader) that really opened me up. He let me play the drums the way I did in Fort Worth when I wasn't playing for other people." John Coltrane's death in July 1967 devastated Jackson. He spent the next few years addicted to heroin. He said, "I couldn't play drums then, spiritually.... I just didn't feel right." From 1970-74, he did not perform, but continued to practice.  In 1974, pianist Onaje Allan Gumbs introduced Jackson to Nichiren Buddhism and chanting. Although initially reluctant, Jackson decided to try it for three weeks. "Then three months had passed. It pulled me together and pulled me out and I was able to focus. I was a Buddhist and a vegetarian for 17 years."  By 1975 he joined saxophonist Ornette Coleman's electric free funk band, Prime Time. During his stint in Prime Time, Coleman taught Jackson composition and harmolodics. Jackson says that Coleman told him he was hearing music "in that piccolo range," and encouraged him to compose on the flute. Jackson went to Paris with Prime Time in 1976 to perform concerts and record Dancing in Your Head and Body Meta.  In 1978, Jackson played on four albums with pianist Cecil Taylor: Cecil Taylor Unit, 3 Phasis, Live in the Black Forest, and One Too Many Salty Swift and Not Goodbye.
Question: What was his career?
Answer: Jackson performed with many jazz musicians,

Problem: Background: Mark David Chapman (born May 10, 1955) is an American murderer who shot and killed John Lennon at the entrance to the Dakota apartment building in New York City on December 8, 1980. Chapman fired five times at Lennon, hitting him four times in the back, and read The Catcher in the Rye until he was arrested by police. He has repeatedly said that the novel was his statement. Chapman's legal team intended to mount an insanity defense that would be based on expert testimony that he was in a delusional psychotic state at the time of the killing.
Context: Chapman's first court-appointed lawyer, Herbert Adlerberg, withdrew from the case amid threats of lynching. Police feared that Lennon fans might storm the hospital, so they transferred Chapman to Rikers Island for his personal safety.  At the initial hearing in January 1981, Chapman's new lawyer, Jonathan Marks, instructed him to enter a plea of not guilty by reason of insanity. In February, Chapman sent a handwritten statement to The New York Times urging everyone to read The Catcher in the Rye, calling it an "extraordinary book that holds many answers." The defense team sought to establish witnesses as to Chapman's mental state at the time of the killing. It was reported they were confident he would be found not guilty by reason of insanity, in which case he would have been committed to a state mental hospital and received treatment.  However, in June, Chapman told Marks that he wanted to drop the insanity defense and plead guilty. Marks objected with "serious questions" over Chapman's sanity, and legally challenged his competence to make this decision. In the pursuant hearing on June 22, Chapman said that God had told him to plead guilty and that he would not change his plea or ever appeal, regardless of his sentence. Marks told the court that he opposed Chapman's change of plea but that Chapman would not listen to him. Judge Dennis Edwards refused a further assessment, saying that Chapman had made the decision of his own free will, and declared him competent to plead guilty.
Question: Why did he want to change to a guilty plea?
Answer: Chapman said that God had told him to plead guilty

Problem: Background: Richard John Santorum (born May 10, 1958) is an American attorney, author, politician, and CNN Senior Political Commentator. A member of the Republican Party, he served as a United States Senator from Pennsylvania from 1995 to 2007 and was the Senate's third-ranking Republican from 2001 to 2007. He ran as a candidate for the 2012 Republican Party presidential nomination, finishing second to Mitt Romney. Santorum was elected as a United States Senator from Pennsylvania in 1994.
Context: Santorum served in the United States Senate representing Pennsylvania from 1995 to 2007. From 2001 until 2007, he was the Senate's third-ranking Republican. He was first elected to the Senate during the 1994 Republican takeover, narrowly defeating incumbent Democrat Harris Wofford, 49% to 47%. The theme of Santorum's 1994 campaign signs was "Join the Fight!" During the race, he was considered an underdog, as his opponent was 32 years his senior. He was reelected in 2000, defeating U.S. Congressman Ron Klink by a 52-46% margin. In his reelection bid of 2006, he lost to Democrat Bob Casey, Jr. by a 59-41% margin.  After his election to the Senate in 1994, Santorum sought to "practice what [he] preached" and hired five people for his staff who were on welfare, food stamps, or other government aid.  In 1996, Santorum served as Chairman of the Republican Party Task Force on Welfare Reform, and contributed to legislation that became the Personal Responsibility and Work Opportunity Act. Santorum was an author and the floor manager of the bill. In 1996, Santorum endorsed moderate Republican Arlen Specter in his short-lived campaign for president. Reporters have observed that though Santorum and Specter differed on social policy, Specter provided him with key political staff for his successful run in 1994.  The National Taxpayers Union, a fiscal conservative organization, gave Santorum an "A-" score for his votes on fiscal issues, meaning that he was one of "the strongest supporters of responsible tax and spending policies" during his tenure, and ranked fifth in the group's rankings out of 50 senators who served at the same time.
Question: What was his first notable accomplishment as a senator?
