Input: Richard Feynman
From his diagrams of a small number of particles interacting in spacetime, Feynman could then model all of physics in terms of the spins of those particles and the range of coupling of the fundamental forces. Feynman attempted an explanation of the strong interactions governing nucleons scattering called the parton model. The parton model emerged as a complement to the quark model developed by his Caltech colleague Murray Gell-Mann. The relationship between the two models was murky; Gell-Mann referred to Feynman's partons derisively as "put-ons". In the mid-1960s, physicists believed that quarks were just a bookkeeping device for symmetry numbers, not real particles, as the statistics of the Omega-minus particle, if it were interpreted as three identical strange quarks bound together, seemed impossible if quarks were real. The Stanford linear accelerator deep inelastic scattering experiments of the late 1960s showed, analogously to Ernest Rutherford's experiment of scattering alpha particles on gold nuclei in 1911, that nucleons (protons and neutrons) contained point-like particles that scattered electrons. It was natural to identify these with quarks, but Feynman's parton model attempted to interpret the experimental data in a way that did not introduce additional hypotheses. For example, the data showed that some 45% of the energy momentum was carried by electrically-neutral particles in the nucleon. These electrically-neutral particles are now seen to be the gluons that carry the forces between the quarks and carry also the three-valued color quantum number that solves the Omega-minus problem. Feynman did not dispute the quark model; for example, when the fifth quark was discovered in 1977, Feynman immediately pointed out to his students that the discovery implied the existence of a sixth quark, which was discovered in the decade after his death.

What model did Feynman produce to complement the quark model?
Output: parton model


Input: Article: At the start of John's reign there was a sudden change in prices, as bad harvests and high demand for food resulted in much higher prices for grain and animals. This inflationary pressure was to continue for the rest of the 13th century and had long-term economic consequences for England. The resulting social pressures were complicated by bursts of deflation that resulted from John's military campaigns. It was usual at the time for the king to collect taxes in silver, which was then re-minted into new coins; these coins would then be put in barrels and sent to royal castles around the country, to be used to hire mercenaries or to meet other costs. At those times when John was preparing for campaigns in Normandy, for example, huge quantities of silver had to be withdrawn from the economy and stored for months, which unintentionally resulted in periods during which silver coins were simply hard to come by, commercial credit difficult to acquire and deflationary pressure placed on the economy. The result was political unrest across the country. John attempted to address some of the problems with the English currency in 1204 and 1205 by carrying out a radical overhaul of the coinage, improving its quality and consistency.

Now answer this question: How long did the inflationary pressure continue?

Output: 13th century


Article: Chopin's relations with Sand were soured in 1846 by problems involving her daughter Solange and Solange's fiancé, the young fortune-hunting sculptor Auguste Clésinger. The composer frequently took Solange's side in quarrels with her mother; he also faced jealousy from Sand's son Maurice. Chopin was utterly indifferent to Sand's radical political pursuits, while Sand looked on his society friends with disdain. As the composer's illness progressed, Sand had become less of a lover and more of a nurse to Chopin, whom she called her "third child". In letters to third parties, she vented her impatience, referring to him as a "child," a "little angel", a "sufferer" and a "beloved little corpse." In 1847 Sand published her novel Lucrezia Floriani, whose main characters—a rich actress and a prince in weak health—could be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys. In 1847 he did not visit Nohant, and he quietly ended their ten-year relationship following an angry correspondence which, in Sand's words, made "a strange conclusion to nine years of exclusive friendship." The two would never meet again.

Question: What did Sand begin referring to Chopin as as his illness got worse?
Ans: third child


Here is a question about this article: The Procession, held at sundown, consists of a non-motorized parade through downtown Tucson featuring many floats, sculptures, and memorials, in which the community is encouraged to participate. The parade is followed by performances on an outdoor stage, culminating in the burning of an urn in which written prayers have been collected from participants and spectators. The event is organized and funded by the non-profit arts organization Many Mouths One Stomach, with the assistance of many volunteers and donations from the public and local businesses.
What is the answer to this question: What group runs The Procession?
****
So... Many Mouths One Stomach

 Argentina: The torch relay leg in Buenos Aires, Argentina, held on April 11, began with an artistic show at the Lola Mora amphitheatre in Costanera Sur. In the end of the show the mayor of Buenos Aires Mauricio Macri gave the torch to the first torchbearer, Carlos Espínola. The leg finished at the Buenos Aires Riding Club in the Palermo district, the last torchbearer being Gabriela Sabatini. The 13.8 km route included landmarks like the obelisk and Plaza de Mayo. The day was marked by several pro-Tibet protests, which included a giant banner reading "Free Tibet", and an alternative "human rights torch" that was lit by protesters and paraded along the route the flame was to take. Most of these protests were peaceful in nature, and the torch was not impeded. Chinese immigrants also turned out in support of the Games, but only minor scuffles were reported between both groups. Runners surrounded by rows of security carried the Olympic flame past thousands of jubilant Argentines in the most trouble-free torch relay in nearly a week. People showered the parade route with confetti as banks, government offices and businesses took an impromptu half-day holiday for the only Latin American stop on the flame's five-continent journey.
Where did the Olympic torch relay begin in Argentina?
****
The answer: Buenos Aires


The problem: Answer a question about this article:
Glacial bodies larger than 50,000 km2 (19,000 sq mi) are called ice sheets or continental glaciers. Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces. The only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of fresh water, enough that if both melted, global sea levels would rise by over 70 m (230 ft). Portions of an ice sheet or cap that extend into water are called ice shelves; they tend to be thin with limited slopes and reduced velocities. Narrow, fast-moving sections of an ice sheet are called ice streams. In Antarctica, many ice streams drain into large ice shelves. Some drain directly into the sea, often with an ice tongue, like Mertz Glacier.
At what dimensions are glaciers called ice sheets or continental glaciers?
****
The answer:
50,000 km2 (19,000 sq mi)
