Problem: Background: William James Dixon (July 1, 1915 - January 29, 1992) was an American blues musician, vocalist, songwriter, arranger and record producer. He was proficient in playing both the upright bass and the guitar and was a capable singer, but he is perhaps best known as one of the most prolific songwriters of his time. Next to Muddy Waters, Dixon is recognized as the most influential person in shaping the post-World War II sound of the Chicago blues. Dixon's songs have been recorded by countless musicians in many genres as well as by various ensembles in which he participated.
Context: Dixon left Mississippi for Chicago in 1936. A man of considerable stature, standing 6 and a half feet tall and weighing over 250 pounds, he took up boxing, at which he was successful, winning the Illinois State Golden Gloves Heavyweight Championship (Novice Division) in 1937. He became a professional boxer and worked briefly as Joe Louis's sparring partner, but after four fights he left boxing in a dispute with his manager over money. Dixon met Leonard Caston at a boxing gym, where they would harmonize at times. Dixon performed in several vocal groups in Chicago, but it was Caston that persuaded him to pursue music seriously. Caston built him his first bass, made of a tin can and one string. Dixon's experience singing bass made the instrument familiar. He also learned to play the guitar. In 1939, Dixon was a founding member of the Five Breezes, with Caston, Joe Bell, Gene Gilmore and Willie Hawthorne. The group blended blues, jazz, and vocal harmonies, in the mode of the Ink Spots. Dixon's progress on the upright bass came to an abrupt halt with the advent of World War II, when he refused induction into military service as a conscientious objector and was imprisoned for ten months. He refused to go to war because he would not fight for a nation in which institutionalized racism and racist laws were prevalent. After the war, he formed a group named the Four Jumps of Jive. He then reunited with Caston, forming the Big Three Trio, which went on to record for Columbia Records.
Question: What was his profession?
Answer: he took up boxing,

Problem: Background: Hugo Sanchez Marquez (born 11 July 1958) is a retired Mexican professional footballer and manager, who played as a forward. A prolific goalscorer known for his spectacular strikes and volleys, Sanchez is widely regarded as Mexico's greatest-ever footballer, and one of the greatest players of his generation. In 1999, the International Federation of Football History and Statistics voted Sanchez the 26th best footballer of the 20th century, and the best footballer from the CONCACAF region. In 2004 Sanchez was named in the FIFA 100 list of the world's greatest living players.
Context: Nicknamed Hugol and Pentapichichi, Sanchez was a prolific goalscorer, who usually played as a centre-forward; he is widely regarded as Mexico's greatest-ever footballer, and one of the greatest players of his generation. A quick and mobile striker, with good skills and an eye for goal, he was known for his intelligence, positional sense, movement, and anticipation in the area, and was an accurate and efficient finisher, who was capable of scoring with few touches. Due to his athleticism, Sanchez was good in the air, despite his diminutive stature, and was also known for his ability to score acrobatic and flamboyant goals from spectacular strikes and volleys from any position on the pitch, both inside or outside the area; his mastery of the "Chilena", or "Bicycle kick", was a result of his own early training in gymnastics, and his goals scored in this manner were later dubbed Huguinas. His trademark was to perform a celebratory somersault followed by a fist pump after each goal he scored, in honour of his sister, who was a gymnast and participated in the Montreal Olympics. According to his FIFA profile, Sanchez is credited as the creator of the scorpion kick, which was later popularised by Colombian goalkeeper Rene Higuita. Though he regularly practised the trick in training, the Mexican striker never scored a goal with it in an official match. An accurate penalty taker, Sanchez held the record for most penalties scored in La Liga with 56, until Cristiano Ronaldo broke the record in 2017 after scoring his 57th penalty-kick.
Question: How did he influence Rene Higuita?
Answer: the scorpion kick,

Problem: Background: Sutcliffe was born in Bingley in the West Riding of Yorkshire to a working-class family. He was given a Catholic upbringing by his parents, John William Sutcliffe and his wife Kathleen Frances (nee Coonan). Reportedly a loner, he left school aged fifteen and had a series of menial jobs, including two stints as a gravedigger in the 1960s. Between November 1971 and April 1973, Sutcliffe worked at the Baird Television factory on a packaging line.
Context: West Yorkshire Police were criticised for being inadequately prepared for an investigation on this scale. It was one of the largest investigations by a British police force and predated the use of computers. Information on suspects was stored on handwritten index cards. Aside from difficulties in storing and accessing the paperwork (the floor of the incident room was reinforced to cope with the weight of the paper), it was difficult for officers to overcome the information overload of such a large manual system. Sutcliffe was interviewed nine times, but all information the police had about the case was stored in paper form, making cross-referencing difficult, compounded by television appeals for information which generated thousands more documents. Assistant Chief Constable George Oldfield was criticised for being too focused on a hoax confessional tape that seemed to indicate a perpetrator with a Wearside background, and for ignoring advice from survivors of Sutcliffe's attacks, and several eminent specialists including the FBI, plus dialect analysts such as Stanley Ellis and Jack Windsor Lewis, whom he had also consulted throughout the manhunt, that "Wearside Jack" was a blatant hoaxer. The investigation used it as a point of elimination rather than a line of enquiry and allowed Sutcliffe to avoid scrutiny, as he did not fit the profile of the sender of the tape or letters. The "Wearside Jack" hoaxer was given unusual credibility when analysis of saliva on the envelopes he sent showed he had the same blood group as the Yorkshire Ripper had left at crime scenes, a type shared by only 6% of the population. The hoaxer appeared to know details of the murders which had not been released to the press, but which in fact he had acquired from his local newspaper and pub gossip. The official response to the criticisms led to the implementation of the forerunner of the Home Office Large Major Enquiry System, the development of the Major Incident Computer Application (MICA), developed between West Yorkshire Police and ISIS Computer Services. In response to the police reaction to the murders, the Leeds Revolutionary Feminist Group organised a number of 'Reclaim the Night' marches. The group and other feminists had criticised the police for victim-blaming, especially the suggestion that women should remain indoors at night. Eleven marches in various towns across the United Kingdom took place on the night of 12 November 1977. They made the point that women should be able to walk anywhere without restriction and that they should not be blamed for men's violence. In 1988, the mother of Sutcliffe's last victim, Jacqueline Hill, during action for damages on behalf of her daughter's estate, argued in the High Court that the police had failed to use reasonable care in apprehending the murderer of her daughter in Hill v Chief Constable of West Yorkshire. The House of Lords held that the Chief Constable of West Yorkshire did not owe a duty of care to the victim due to the lack of proximity and therefore failing on the second limb of the Caparo test.
