Problem: Tucson, Arizona:

Since 2009, the Tucson Festival of Books has been held annually over a two-day period in March at the University of Arizona. By 2010 it had become the fourth largest book festival in the United States, with 450 authors and 80,000 attendees. In addition to readings and lectures, it features a science fair, varied entertainment, food, and exhibitors ranging from local retailers and publishers to regional and national nonprofit organizations. In 2011, the Festival began presenting a Founder's Award; recipients include Elmore Leonard and R.L. Stine.

Problem: For the remaining years of Richard's reign, John supported his brother on the continent, apparently loyally. Richard's policy on the continent was to attempt to regain through steady, limited campaigns the castles he had lost to Philip II whilst on crusade. He allied himself with the leaders of Flanders, Boulogne and the Holy Roman Empire to apply pressure on Philip from Germany. In 1195 John successfully conducted a sudden attack and siege of Evreux castle, and subsequently managed the defences of Normandy against Philip. The following year, John seized the town of Gamaches and led a raiding party within 50 miles (80 km) of Paris, capturing the Bishop of Beauvais. In return for this service, Richard withdrew his malevolentia (ill-will) towards John, restored him to the county of Gloucestershire and made him again the Count of Mortain.
Who was the Count of Mortain?

Answer: John

Strasbourg's historic city centre, the Grande Ile (Grand Island), was classified a World Heritage site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. Strasbourg is immersed in the Franco-German culture and although violently disputed throughout history, has been a bridge of unity between France and Germany for centuries, especially through the University of Strasbourg, currently the second largest in France, and the coexistence of Catholic and Protestant culture. The largest Islamic place of worship in France, the Strasbourg Grand Mosque, was inaugurated by French Interior Minister Manuel Valls on 27 September 2012.
What is the largest Islamic place of worship in France?
A: Strasbourg Grand Mosque

Context and question: Perhaps the most prominent, controversial and far-reaching theory in all of science has been the theory of evolution by natural selection put forward by the British naturalist Charles Darwin in his book On the Origin of Species in 1859. Darwin proposed that the features of all living things, including humans, were shaped by natural processes over long periods of time. The theory of evolution in its current form affects almost all areas of biology. Implications of evolution on fields outside of pure science have led to both opposition and support from different parts of society, and profoundly influenced the popular understanding of "man's place in the universe". In the early 20th century, the study of heredity became a major investigation after the rediscovery in 1900 of the laws of inheritance developed by the Moravian monk Gregor Mendel in 1866. Mendel's laws provided the beginnings of the study of genetics, which became a major field of research for both scientific and industrial research. By 1953, James D. Watson, Francis Crick and Maurice Wilkins clarified the basic structure of DNA, the genetic material for expressing life in all its forms. In the late 20th century, the possibilities of genetic engineering became practical for the first time, and a massive international effort began in 1990 to map out an entire human genome (the Human Genome Project).
What was the name of the book that Darwin wrote about evolution?
Answer: On the Origin of Species

Question: On June 16, 1911, their four companies were consolidated in New York State by Charles Ranlett Flint to form the Computing-Tabulating-Recording Company (CTR). CTR's business office was in Endicott. The individual companies owned by CTR continued to operate using their established names until the businesses were integrated in 1933 and the holding company eliminated. The four companies had 1,300 employees and offices and plants in Endicott and Binghamton, New York; Dayton, Ohio; Detroit, Michigan; Washington, D.C.; and Toronto. They manufactured machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards.
Is there an answer to this question: How many employees worked at the holding company in 1911?

The similarities between Czech and Slovak led to the languages being considered a single language by a group of 19th-century scholars who called themselves "Czechoslavs" (Cechoslovaci), believing that the peoples were connected in a way which excluded German Bohemians and (to a lesser extent) Hungarians and other Slavs. During the First Czechoslovak Republic (19181938), although "Czechoslovak" was designated as the republic's official language both Czech and Slovak written standards were used. Standard written Slovak was partially modeled on literary Czech, and Czech was preferred for some official functions in the Slovak half of the republic. Czech influence on Slovak was protested by Slovak scholars, and when Slovakia broke off from Czechoslovakia in 1938 as the Slovak State (which then aligned with Nazi Germany in World War II) literary Slovak was deliberately distanced from Czech. When the Axis powers lost the war and Czechoslovakia reformed, Slovak developed somewhat on its own (with Czech influence); during the Prague Spring of 1968, Slovak gained independence from (and equality with) Czech. Since then, "Czechoslovak" refers to improvised pidgins of the languages which have arisen from the decrease in mutual intelligibility.
What was standard written Slovak partially modeled on?
A:
literary Czech
