Example Input: Passage: The traditional energy supply of Thuringia is lignite, mined in the bordering Leipzig region. Since 2000, the importance of environmentally unfriendly lignite combustion has declined in favour of renewable energies, which reached an amount of 40% (in 2013), and more clean gas combustion, often carried out as Cogeneration in the municipal power stations. The most important forms of renewable energies are Wind power and Biomass, followed by Solar energy and Hydroelectricity. Furthermore, Thuringia hosts two big pumped storage stations: the Goldisthal Pumped Storage Station and the Hohenwarte Dam.
Example Output: What is Thuringia's new energy supply?

Example Input: Passage: In Virginia prior to 1920, for example, a person was legally white if having seven-eights or more white ancestry. The one-drop rule originated in some Southern United States in the late 19th century, likely in response to whites' attempt to maintain white supremacy and limit black political power following the Democrats' regaining control of state legislatures in the late 1870s. The first year in which the U.S. Census dropped the mulatto category was 1920; that year enumerators were instructed to classify people in a binary way as white or black. This was a result of the Southern-dominated Congress convincing the Census Bureau to change its rules.
Example Output:
When was a person legally white in South Carolina before 1920?
