input: Please answer the following: Question: "What occurred in the 73rd year of the 20th century?" Context: "In November 1973, the city elected Coleman Young as its first black mayor. After taking office, Young emphasized increasing racial diversity in the police department. Young also worked to improve Detroit's transportation system, but tension between Young and his suburban counterparts over regional matters was problematic throughout his mayoral term. In 1976, the federal government offered $600 million for building a regional rapid transit system, under a single regional authority. But the inability of Detroit and its suburban neighbors to solve conflicts over transit planning resulted in the region losing the majority of funding for rapid transit. Following the failure to reach an agreement over the larger system, the City moved forward with construction of the elevated downtown circulator portion of the system, which became known as the Detroit People Mover." Answer:
++++++++++
output: the city elected Coleman Young as its first black mayor

Please answer this: Question: "How is light coming from a bulb documented?" Context: "An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability." Answer:
++++++++
Answer: percentage

Problem: Question: "What is the irregularities of the surface smaller than for specular reflection?" Context: "The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case." Answer:

A: wavelength

Problem: Given the question: Question: "From where is hydroelectricity obtained?" Context: "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." Answer:
++++++++++++++++++++++++++++++++
The answer is:
Hohenwarte Dam

input question: Question: "What system of thought was the credo that follows the Jewish man known as the Messiah facing off against in the rush to gain adherents?" Context: "Religious beliefs in the Eastern Empire and Persia were in flux during the late 6th and early 7th centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it.[J] Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634635 and reaching Egypt in 640641, Persia between 637 and 642, North Africa in the later 7th century, and the Iberian Peninsula in 711. By 714, Islamic forces controlled much of the peninsula in a region they called Al-Andalus." Answer:???
output answer: Zoroastrianism

input question: Question: "The Talmud has a lenient position, also considered?" Context: "However, the Orthodox claim to absolute fidelity to past tradition has been challenged by scholars who contend that the Judaism of the Middle Ages bore little resemblance to that practiced by today's Orthodox. Rather, the Orthodox community, as a counterreaction to the liberalism of the Haskalah movement, began to embrace far more stringent halachic practices than their predecessors, most notably in matters of Kashrut and Passover dietary laws, where the strictest possible interpretation becomes a religious requirement, even where the Talmud explicitly prefers a more lenient position, and even where a more lenient position was practiced by prior generations." Answer:???
output answer:
liberalism
