Input: Consider Input: A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. This antigen/antibody complex is taken up by the B cell and processed by proteolysis into peptides. The B cell then displays these antigenic peptides on its surface MHC class II molecules. This combination of MHC and antigen attracts a matching helper T cell, which releases lymphokines and activates the B cell. As the activated B cell then begins to divide, its offspring (plasma cells) secrete millions of copies of the antibody that recognizes this antigen. These antibodies circulate in blood plasma and lymph, bind to pathogens expressing the antigen and mark them for destruction by complement activation or for uptake and destruction by phagocytes. Antibodies can also neutralize challenges directly, by binding to bacterial toxins or by interfering with the receptors that viruses and bacteria use to infect cells.

Output: What kind of cell identifies pathogens when the antibodies on its surface complex with a specific foreign antigen?


Input: Consider Input: The men's basketball team has over 1,600 wins, one of only 12 schools who have reached that mark, and have appeared in 28 NCAA tournaments. Former player Austin Carr holds the record for most points scored in a single game of the tournament with 61. Although the team has never won the NCAA Tournament, they were named by the Helms Athletic Foundation as national champions twice. The team has orchestrated a number of upsets of number one ranked teams, the most notable of which was ending UCLA's record 88-game winning streak in 1974. The team has beaten an additional eight number-one teams, and those nine wins rank second, to UCLA's 10, all-time in wins against the top team. The team plays in newly renovated Purcell Pavilion (within the Edmund P. Joyce Center), which reopened for the beginning of the 2009–2010 season. The team is coached by Mike Brey, who, as of the 2014–15 season, his fifteenth at Notre Dame, has achieved a 332-165 record. In 2009 they were invited to the NIT, where they advanced to the semifinals but were beaten by Penn State who went on and beat Baylor in the championship. The 2010–11 team concluded its regular season ranked number seven in the country, with a record of 25–5, Brey's fifth straight 20-win season, and a second-place finish in the Big East. During the 2014-15 season, the team went 32-6 and won the ACC conference tournament, later advancing to the Elite 8, where the Fighting Irish lost on a missed buzzer-beater against then undefeated Kentucky. Led by NBA draft picks Jerian Grant and Pat Connaughton, the Fighting Irish beat the eventual national champion Duke Blue Devils twice during the season. The 32 wins were the most by the Fighting Irish team since 1908-09.

Output: How many wins does the Notre Dame men's basketball team have?


Input: Consider Input: After the formal end of Reconstruction, the struggle over power in Southern society continued. Through violence and intimidation against freedmen and their allies, White Democrats regained political power in Tennessee and other states across the South in the late 1870s and 1880s. Over the next decade, the state legislature passed increasingly restrictive laws to control African Americans. In 1889 the General Assembly passed four laws described as electoral reform, with the cumulative effect of essentially disfranchising most African Americans in rural areas and small towns, as well as many poor Whites. Legislation included implementation of a poll tax, timing of registration, and recording requirements. Tens of thousands of taxpaying citizens were without representation for decades into the 20th century. Disfranchising legislation accompanied Jim Crow laws passed in the late 19th century, which imposed segregation in the state. In 1900, African Americans made up nearly 24% of the state's population, and numbered 480,430 citizens who lived mostly in the central and western parts of the state.
Output: Who were targeted by restrictive laws passed in Southern states at the end of the 19th century?
