<human>: 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. CANNOTANSWERAnswer this question using a quote from the following article:
