Input: Read this: Geography effects solar energy potential because areas that are closer to the equator have a greater amount of solar radiation. However, the use of photovoltaics that can follow the position of the sun can significantly increase the solar energy potential in areas that are farther from the equator. Time variation effects the potential of solar energy because during the nighttime there is little solar radiation on the surface of the Earth for solar panels to absorb. This limits the amount of energy that solar panels can absorb in one day. Cloud cover can effect the potential of solar panels because clouds block incoming light from the sun and reduce the light available for solar cells.
Question: What effect does cloud coverage have on the amount of solar energy available?

Output: clouds block incoming light from the sun and reduce the light available for solar cells

QUES: The success of its football team made Notre Dame a household name. The success of Note Dame reflected rising status of Irish Americans and Catholics in the 1920s. Catholics rallied up around the team and listen to the games on the radio, especially when it knocked off the schools that symbolized the Protestant establishment in America Harvard, Yale, Princeton, and Army. Yet this role as high-profile flagship institution of Catholicism made it an easy target of anti-Catholicism. The most remarkable episode of violence was the clash between Notre Dame students and the Ku Klux Klan in 1924. Nativism and anti-Catholicism, especially when directed towards immigrants, were cornerstones of the KKK's rhetoric, and Notre Dame was seen as a symbol of the threat posed by the Catholic Church. The Klan decided to have a week-long Klavern in South Bend. Clashes with the student body started on March 17, when students, aware of the anti-Catholic animosity, blocked the Klansmen from descending from their trains in the South Bend station and ripped the KKK clothes and regalia. On May 19 thousands of students massed downtown protesting the Klavern, and only the arrival of college president Fr. Matthew Walsh prevented any further clashes. The next day, football coach Knute Rockne spoke at a campus rally and implored the students to obey the college president and refrain from further violence. A few days later the Klavern broke up, but the hostility shown by the students was an omen and a contribution to the downfall of the KKK in Indiana.

Which college president of Notre Dame is credited with preventing more confrontations between students and the KKK?
What is the answer?
ANS: Fr. Matthew Walsh

QUES: On an international level the German DIN 4512 system has been effectively superseded in the 1980s by ISO 6:1974, ISO 2240:1982, and ISO 5800:1979 where the same sensitivity is written in linear and logarithmic form as "ISO 100/21" (now again with degree symbol). These ISO standards were subsequently adopted by DIN as well. Finally, the latest DIN 4512 revisions were replaced by corresponding ISO standards, DIN 4512-1:1993-05 by DIN ISO 6:1996-02 in September 2000, DIN 4512-4:1985-08 by DIN ISO 2240:1998-06 and DIN 4512-5:1990-11 by DIN ISO 5800:1998-06 both in July 2002.
When did the ISO adopt the DIN standards?

ANS: unanswerable

The native language of Germans is German, a West Germanic language, related to and classified alongside English and Dutch, and sharing many similarities with the North Germanic and Scandinavian languages. Spoken by approximately 100 million native speakers, German is one of the world's major languages and the most widely spoken first language in the European Union. German has been replaced by English as the dominant language of science-related Nobel Prize laureates during the second half of the 20th century. It was a lingua franca in the Holy Roman Empire.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many natives speak German?
Ah, so.. 100 million

Question: In 530 BC Cyrus the Great, King of the Persian Achaemenid Empire crossed the Hindu-Kush mountains to seek tribute from the tribes of Kamboja, Gandhara and the trans-India region (modern Afghanistan and Pakistan). By 520 BC, during the reign of Darius I of Persia, much of the northwestern subcontinent (present-day eastern Afghanistan and Pakistan) came under the rule of the Persian Achaemenid Empire, as part of the far easternmost territories. The area remained under Persian control for two centuries. During this time India supplied mercenaries to the Persian army then fighting in Greece.
Try to answer this question if possible: By 520 BC what empire ruled the northwestern Indian subcontinent?
Answer: Persian Achaemenid Empire

QUES: The city receives 49.9 inches (1,270 mm) of precipitation annually, which is fairly spread throughout the year. Average winter snowfall between 1981 and 2010 has been 25.8 inches (66 cm), but this varies considerably from year to year. Hurricanes and tropical storms are rare in the New York area, but are not unheard of and always have the potential to strike the area. Hurricane Sandy brought a destructive storm surge to New York City on the evening of October 29, 2012, flooding numerous streets, tunnels, and subway lines in Lower Manhattan and other areas of the city and cutting off electricity in many parts of the city and its suburbs. The storm and its profound impacts have prompted the discussion of constructing seawalls and other coastal barriers around the shorelines of the city and the metropolitan area to minimize the risk of destructive consequences from another such event in the future.
The mean snowfall between 1981 and 2010 in NYC has been how many inches?

ANS:
25.8
