Input: Read this: 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.
Question: What year was Koch awarded a Nobel Prize?

Output: 1905

Question: On what date was a study created to research the impart on men in direct involvement?

Output: unanswerable

Representations of dogs became more elaborate as individual breeds evolved and the relationships between human and canine developed.

Input: Read this: According to the U.S. Census Bureau, as of 2015, Tennessee had an estimated population of 6,600,299, which is an increase of 50,947, from the prior year and an increase of 254,194, or 4.01%, since the year 2010. This includes a natural increase since the last census of 142,266 people (that is 493,881 births minus 351,615 deaths), and an increase from net migration of 219,551 people into the state. Immigration from outside the United States resulted in a net increase of 59,385 people, and migration within the country produced a net increase of 160,166 people. Twenty percent of Tennesseans were born outside the South in 2008, compared to a figure of 13.5% in 1990.
Question: How much of Tennessee's population increase between 2010 and 2015 was due to migration?

Output:
219,551
