Problem: Tuberculosis:

Tuberculosis caused the most widespread public concern in the 19th and early 20th centuries as an endemic disease of the urban poor. In 1815, one in four deaths in England was due to "consumption". By 1918, one in six deaths in France was still caused by TB. After TB was determined to be contagious, in the 1880s, it was put on a notifiable disease list in Britain; campaigns were started to stop people from spitting in public places, and the infected poor were "encouraged" to enter sanatoria that resembled prisons (the sanatoria for the middle and upper classes offered excellent care and constant medical attention). Whatever the (purported) benefits of the "fresh air" and labor in the sanatoria, even under the best conditions, 50% of those who entered died within five years (circa 1916).

When were deaths from TB in England reduced to one in six?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1866, the feud between Austria and Prussia finally came to a head. There were several reasons behind this war. As German nationalism grew strongly inside the German Confederation and neither could decide on how Germany was going to be unified into a nation-state. The Austrians favoured the Greater Germany unification but were not willing to give up any of the non-German-speaking land inside of the Austrian Empire and take second place to Prussia. The Prussians however wanted to unify Germany as Little Germany primarily by the Kingdom of Prussia, whilst excluding Austria. In the final battle of the German war (Battle of Koniggratz) the Prussians successfully defeated the Austrians and succeeded in creating the North German Confederation.
What did the Prussians want Germany to unify under?
A: Little Germany

Problem: Pharmaceutical industry:

Others have argued that excessive regulation suppresses therapeutic innovation, and that the current cost of regulator-required clinical trials prevents the full exploitation of new genetic and biological knowledge for the treatment of human disease. A 2012 report by the President's Council of Advisors on Science and Technology made several key recommendations to reduce regulatory burdens to new drug development, including 1) expanding the FDA's use of accelerated approval processes, 2) creating an expedited approval pathway for drugs intended for use in narrowly defined populations, and 3) undertaking pilot projects designed to evaluate the feasibility of a new, adaptive drug approval process.

What can be used to evaluate new human diseases?
