Here is a question about this article: Although Max insisted von Neumann attend school at the grade level appropriate to his age, he agreed to hire private tutors to give him advanced instruction in those areas in which he had displayed an aptitude. At the age of 15, he began to study advanced calculus under the renowned analyst Gábor Szegő. On their first meeting, Szegő was so astounded with the boy's mathematical talent that he was brought to tears. Some of von Neumann's instant solutions to the problems in calculus posed by Szegő, sketched out on his father's stationery, are still on display at the von Neumann archive in Budapest. By the age of 19, von Neumann had published two major mathematical papers, the second of which gave the modern definition of ordinal numbers, which superseded Georg Cantor's definition. At the conclusion of his education at the gymnasium, von Neumann sat for and won the Eötvös Prize, a national prize for mathematics.
What is the answer to this question: At what age did Von Neumann begin to study advance calculus?
****
So... 15

Question: Read this and answer the question

In Mexico, Carnival is celebrated in about 225 cities and towns. The largest is in Mazatlán and the city of Veracruz with others in Baja California and Yucatán. The larger city Carnivals employ costumes, elected queens and parades with floats, but Carnival celebrations in smaller and rural areas vary widely depending on the level of European influence during Mexico's colonial period. The largest of these is in Huejotzingo, Puebla where most townspeople take part in mock combat with rifles shooting blanks, roughly based on the Battle of Puebla. Other important states with local traditions include Morelos, Oaxaca, Tlaxcala and Chiapas.

What is the mock combat roughly based on?
Answer: the Battle of Puebla


Problem: There is disagreement whether madaris ever became universities. Scholars like Arnold H. Green and Seyyed Hossein Nasr have argued that starting in the 10th century, some medieval Islamic madaris indeed became universities. George Makdisi and others, however, argue that the European university has no parallel in the medieval Islamic world. Darleen Pryds questions this view, pointing out that madaris and European universities in the Mediterranean region shared similar foundations by princely patrons and were intended to provide loyal administrators to further the rulers' agenda. Other scholars regard the university as uniquely European in origin and characteristics.
What class of people founded both European universities and Islamic madaris
The answer is the following: princely patrons


Input: Article: Market strategist Phil Dow believes distinctions exist "between the current market malaise" and the Great Depression. He says the Dow Jones average's fall of more than 50% over a period of 17 months is similar to a 54.7% fall in the Great Depression, followed by a total drop of 89% over the following 16 months. "It's very troubling if you have a mirror image," said Dow. Floyd Norris, the chief financial correspondent of The New York Times, wrote in a blog entry in March 2009 that the decline has not been a mirror image of the Great Depression, explaining that although the decline amounts were nearly the same at the time, the rates of decline had started much faster in 2007, and that the past year had only ranked eighth among the worst recorded years of percentage drops in the Dow. The past two years ranked third, however.

Now answer this question: How much did the Dow Jones average fall during a period of 17 months?

Output:
50%
