Here is a question about this article: The British and French struggles in India became but one theatre of the global Seven Years' War (17561763) involving France, Britain and the other major European powers. The signing of the Treaty of Paris (1763) had important consequences for the future of the British Empire. In North America, France's future as a colonial power there was effectively ended with the recognition of British claims to Rupert's Land, and the ceding of New France to Britain (leaving a sizeable French-speaking population under British control) and Louisiana to Spain. Spain ceded Florida to Britain. Along with its victory over France in India, the Seven Years' War therefore left Britain as the world's most powerful maritime power.
What is the answer to this question: When was the Treaty of Paris?
****
So... 1763

Here is a question about this article: 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 is the answer to this question: What did Koch call the ineffective treatment for TB he came up with in 1890?
****
So...
tuberculin
