The bacillus causing tuberculosis, M. tuberculosis, was identified and described on 24 March 1882 by Robert Koch. He received the Nobel Prize in physiology or medicine in 1905 for this discovery. Koch did not believe the bovine (cattle) and human tuberculosis diseases were similar, which delayed the recognition of infected milk as a source of infection. Later, the risk of transmission from this source was dramatically reduced by the invention of the pasteurization process. Koch announced a glycerine extract of the tubercle bacilli as a "remedy" for tuberculosis in 1890, calling it "tuberculin". While it was not effective, it was later successfully adapted as a screening test for the presence of pre-symptomatic tuberculosis. The World Tuberculosis Day was established on 24 March for this reason.
What did Koch call the ineffective treatment for TB he came up with in 1890?
****
The answer: tuberculin

From 1966, Witness publications and convention talks built anticipation of the possibility that Christ's thousand-year reign might begin in late 1975 or shortly thereafter. The number of baptisms increased significantly, from about 59,000 in 1966 to more than 297,000 in 1974. By 1975, the number of active members exceeded two million. Membership declined during the late 1970s after expectations for 1975 were proved wrong. Watch Tower Society literature did not state dogmatically that 1975 would definitely mark the end, but in 1980 the Watch Tower Society admitted its responsibility in building up hope regarding that year.
What did the Watch Tower Society admit in 1980?
****
The answer: its responsibility in building up hope

Protestants have founded hospitals, homes for disabled or elderly people, educational institutions, organizations that give aid to developing countries, and other social welfare agencies. In the nineteenth century, throughout the Anglo-American world, numerous dedicated members of all Protestant denominations were active in social reform movements such as the abolition of slavery, prison reforms, and woman suffrage. As an answer to the "social question" of the nineteenth century, Germany under Chancellor Otto von Bismarck introduced insurance programs that led the way to the welfare state (health insurance, accident insurance, disability insurance, old-age pensions). To Bismarck this was "practical Christianity". These programs, too, were copied by many other nations, particularly in the Western world.
What did Bismarck consider social insurance programs to be?
****
The answer: practical Christianity

Madonna's look and style of dressing, her performances, and her music videos influenced young girls and women. Her style became one of the female fashion trends of the 1980s. Created by stylist and jewelry designer Maripol, the look consisted of lace tops, skirts over capri pants, fishnet stockings, jewelry bearing the crucifix, bracelets, and bleached hair. Madonna achieved global recognition after the release of her second studio album, Like a Virgin, in November 1984. It topped the charts in several countries and became her first number one album on the Billboard 200. The title track, "Like a Virgin", topped the Billboard Hot 100 chart for six consecutive weeks.

November 1984
