Problem: Thuringia:

The most important river in Thuringia is the Saale (a tributary of the Elbe) with its tributaries Unstrut, Ilm and Weiße Elster, draining the most parts of Thuringia and the Werra (the headwater of the Weser), draining the south-west and west of the Land. Furthermore, some small parts on the southern border are drained by tributaries of the Main (a tributary of the Rhine). There are no large natural lakes in Thuringia, but it does have some of Germany's biggest dams including the Bleiloch Dam and the Hohenwarte Dam at Saale river same as the Leibis-Lichte Dam and the Goldisthal Pumped Storage Station within the Highland. Thuringia is Germany's only state without connection to navigable waterways.

Problem: Yale University:

Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.

Who teaches Yale's residential college's graduate classes?

A: unanswerable


Problem: Napoleon:

The official introduction of the metric system in September 1799 was unpopular in large sections of French society. Napoleon's rule greatly aided adoption of the new standard not only across France but also across the French sphere of influence. Napoleon ultimately took a retrograde step in 1812 when he passed legislation to introduce the mesures usuelles (traditional units of measurement) for retail trade—a system of measure that resembled the pre-revolutionary units but were based on the kilogram and the metre; for example the livre metrique (metric pound) was 500 g instead of 489.5 g—the value of the livre du roi (the king's pound). Other units of measure were rounded in a similar manner. This however laid the foundations for the definitive introduction of the metric system across Europe in the middle of the 19th century.

What year did Napoleon pass legislation that introduced traditional units of measurement for retail trade?
---
A:
1812
