Input: Consider Input: Passage: At the same time, naval innovations led to a German domination of trade in the Baltic Sea and parts of Eastern Europe through the Hanseatic League. Along the trade routes, Hanseatic trade stations became centers of the German culture. German town law (Stadtrecht) was promoted by the presence of large, relatively wealthy German populations, their influence and political power. Thus people who would be considered "Germans", with a common culture, language, and worldview different from that of the surrounding rural peoples, colonized trading towns as far north of present-day Germany as Bergen (in Norway), Stockholm (in Sweden), and Vyborg (now in Russia). The Hanseatic League was not exclusively German in any ethnic sense: many towns who joined the league were outside the Holy Roman Empire and a number of them may only loosely be characterized as German. The Empire itself was not entirely German either. It had a multi-ethnic and multi-lingual structure, some of the smaller ethnicities and languages used at different times were Dutch, Italian, French, Czech and Polish. Question: What other ethnicities, besides German were part of The Empire?

Output: Dutch, Italian, French, Czech and Polish

Input: Consider Input: Passage: These statistics point to the complexities surrounding the lack of health/nutrition literacy and reveal the degree to which they are embedded in the social structure and interconnected with other problems. Among these problems are the lack of information about food choices, a lack of understanding of nutritional information and its application to individual circumstances, limited or difficult access to healthful foods, and a range of cultural influences and socioeconomic constraints such as low levels of education and high levels of poverty that decrease opportunities for healthful eating and living. Question: Aside from large people living in poverty, what else is considered a socioeconomic constraint that resulted in a decrease in opportunity for healthy food choices?

Output: low levels of education

Input: Consider Input: Passage: The Cathedral of Brasilia in the capital of the Federative Republic of Brazil, is an expression of the architect Oscar Niemeyer. This concrete-framed hyperboloid structure, seems with its glass roof reaching up, open, to the heavens. On 31 May 1970, the Cathedral's structure was finished, and only the 70 m (229.66 ft) diameter of the circular area were visible. Niemeyer's project of Cathedral of Brasilia is based in the hyperboloid of revolution which sections are asymmetric. The hyperboloid structure itself is a result of 16 identical assembled concrete columns. These columns, having hyperbolic section and weighing 90 t, represent two hands moving upwards to heaven. The Cathedral was dedicated on 31 May 1970. Question: When was the Cathedral of Brasilia dedicated?
Output: 31 May 1970
