input: Zheng He's sailing charts, the Mao Kun map, were published in a book entitled the Wubei Zhi (A Treatise on Armament Technology) written in 1621 and published in 1628 but traced back to Zheng He's and earlier voyages. It was originally a strip map 20.5 cm by 560 cm that could be rolled up, but was divided into 40 pages which vary in scale from 7 miles/inch in the Nanjing area to 215 miles/inch in parts of the African coast.  Investigation into folios 19V to 20R of the Mao Kun Map which covers the Indian Ocean including the South India, Sri Lanka, the Maldives, and East Africa suggests that it is a composite of four maps, one for Sri Lanka, one for South India one for the Maldives and one for around 400 km of the East African coast, no further south than 6 degrees south of the Equator. Each of these maps is positioned at a different orientation to fit with the ocean currents and winds required of a sailing chart, rather than a formal map. The analysis also suggests that Arabic-speaking pilots with a detailed knowledge of the African coast were involved in the cartography.  There is little attempt to provide an accurate 2-D representation; instead the sailing instructions are given using a 24-point compass system with a Chinese symbol for each point, together with a sailing time or distance, which takes account of the local currents and winds. Sometimes depth soundings are also provided. It also shows bays, estuaries, capes and islands, ports and mountains along the coast, important landmarks such as pagodas and temples, and shoal rocks. Of 300 named places outside China, more than 80% can be confidently located. There are also fifty observations of stellar altitude.

Problem: Background: Wentz was born Peter Lewis Kingston Wentz III, in Wilmette, Illinois, an affluent suburb of Chicago. He is the son of Dale (nee Lewis), a high school admissions counselor, and Pete Wentz II, an attorney. He is of English and German descent on his father's side and Afro-Jamaican on his mother's side. He has a younger sister, Hillary, and a younger brother, Andrew.
Context: Apart from his musical career, Wentz has been involved in various entrepreneurial ventures. Fall Out Boy bandmate Patrick Stump says of Wentz's endeavors: "It scares me sometimes, watching him. The two seconds you're not with that dude he's made 30 decisions that are going to affect our band for the rest of the year." Wentz's company, Clandestine Industries, distributes books, clothing, and other merchandise. On August 2, 2007, fashion company DKNY joined a partnership with Clandestine Industries. Wentz himself has served as a model on the DKNY/Clandestine promo website.  In April 2007, Pete came out with his own signature Squier Precision Bass. It has a black body with a red shell pickguard and special graphics that include Wentz's own red bat/heart design on the body, plus a black bat/diamond fingerboard inlay at the 12th fret. It also features Wentz's signature on the back of the headstock. Wentz owns a very similar custom Fender bass with a purple pickguard and bat/heart. In 2008, Fender gave his son, Bronx Wentz, a three-quarter-sized modified version of his guitar.  Wentz opened a nightclub in New York with his bandmates as well as members of Gym Class Heroes, The Academy Is..., and Cobra Starship; the bands' managers are also involved in the enterprise. Called Angels & Kings, the club occupies the former space on 11th Street near Avenue A that housed the Orchid Lounge. Notable guests, including Tommy Hilfiger, arrived for the grand opening on April 20, 2007. In June 2007, Wentz celebrated the opening of Angels & Kings' second location in Chicago.  On December 13, 2008, Wentz, along with Travis McCoy of Gym Class Heroes, created several pieces for an art exhibit at Gallery 1988 in Los Angeles called "Without You, I'm Just Me." The exhibit closed on December 24, 2008. Wentz appeared in the season 5 episode of CSI: NY, "Point of No Return", along with then-wife Ashlee Simpson. Wentz also hosted the Australia MTV VMAs on March 27, 2009.  Wentz collaborated with Mark Hoppus on the track "In Transit" on the Almost Alice soundtrack for the 2010 movie, Alice in Wonderland. He was also a judge for the 10th and 11th annual Independent Music Awards to support independent artists' careers.

Question: Benjamin Solomon Carson Sr. (born September 18, 1951) is an American neurosurgeon, author and politician serving as the 17th and current United States Secretary of Housing and Urban Development since 2017, under the Trump Administration. Prior to his cabinet position, he was a candidate for President of the United States in the Republican primaries in 2016. Born in Detroit, Michigan, and a graduate of Yale University and the University of Michigan Medical School, Carson has authored numerous books on his medical career and political stances.

By ninth grade, the family's financial situation had improved, his mother surprising neighbors by paying cash to buy a new Chrysler car, and the only government assistance they still relied on was food stamps. Carson attended the predominantly black Southwestern High School for ninth through 12th grades, graduating third in his class academically. In high school he played the baritone horn in the band, and participated in forensics (public speaking), chess club, and the U.S. Army Junior Reserve Officers' Training Corps (JROTC) program where he reached its highest rank--cadet colonel. Carson served as a laboratory assistant in the high school's biology, chemistry, physics school laboratories beginning in 10th, 11th, and 12th grade, respectively, and worked as a biology laboratory assistant at Wayne State University the summer between 11th and 12th grades.  In his book Gifted Hands, Carson relates that as a youth he had a violent temper. "As a teenager, I would go after people with rocks, and bricks, and baseball bats, and hammers," Carson told NBC's Meet the Press in October 2015. He said he once tried to hit his mother on the head with a hammer over a clothing dispute, while in the ninth grade he tried to stab a friend who had changed the radio station. Fortunately, the blade broke in his friend's belt buckle. Carson said that the intended victim, whose identity he wants to protect, was a classmate, a friend, or a close relative. After this incident, Carson said that he began reading the Book of Proverbs and applying verses on anger. As a result, he states he "never had another problem with temper". In his various books and at campaign events, he repeated these stories and said he once attacked a schoolmate with a combination lock. Nine friends, classmates, and neighbors who grew up with him told CNN in 2015 they did not remember the anger or violence he has described. In response, Carson posted on Facebook a 1997 Parade Magazine issue, in which his mother verified the stabbing incident. He then questioned the extent of the effort CNN had exerted in the investigation.  He has said that he protected white students in a biology lab after a race riot broke out at his high school in response to the assassination of Martin Luther King Jr. in 1968. The Wall Street Journal confirmed the riot but could not find anyone who remembered Carson sheltering white students.
