Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
What isotope of uranium is formed when 238U experiences spontaneous fission?
uranium-239


Input: Queen (band)
In 1978, Queen toured the US and Canada, and spent much of 1979 touring in Europe and Japan. They released their first live album, Live Killers, in 1979; it went platinum twice in the US. Queen also released the very successful single "Crazy Little Thing Called Love", a rockabilly inspired song done in the style of Elvis Presley. The song made the top 10 in many countries, topped the Australian ARIA Charts for seven consecutive weeks, and was the band's first number one single in the United States where it topped the Billboard Hot 100 for four weeks. Having written the song on guitar and played rhythm on the record, Mercury played rhythm guitar while performing the song live, which was the first time he ever played guitar in concert. In December 1979, Queen played the opening night at the Concert for the People of Kampuchea in London, having accepted a request by the event's organiser Paul McCartney.

In what year did Queen play the Concert for the People of Kampuchea?
Output: 1979


Input: Article: It is believed that Nanjing was the largest city in the world from 1358 to 1425 with a population of 487,000 in 1400. Nanjing remained the capital of the Ming Empire until 1421, when the third emperor of the Ming dynasty, the Yongle Emperor, relocated the capital to Beijing.

Now answer this question: When did Nanjing cease to be the capital?

Output: 1421


Article: Sweet desserts such as galaktoboureko, and drinks such as ouzo, metaxa and a variety of wines including retsina. Greek cuisine differs widely from different parts of the mainland and from island to island. It uses some flavorings more often than other Mediterranean cuisines: oregano, mint, garlic, onion, dill and bay laurel leaves. Other common herbs and spices include basil, thyme and fennel seed. Many Greek recipes, especially in the northern parts of the country, use "sweet" spices in combination with meat, for example cinnamon and cloves in stews.

Question: What is one of the flavorings commonly used in Greek Mediterranean food? 
Ans: oregano


Here is a question about this article: In April 1994, the results of a Merck-sponsored study, the Scandinavian Simvastatin Survival Study, were announced. Researchers tested simvastatin, later sold by Merck as Zocor, on 4,444 patients with high cholesterol and heart disease. After five years, the study concluded the patients saw a 35% reduction in their cholesterol, and their chances of dying of a heart attack were reduced by 42%. In 1995, Zocor and Mevacor both made Merck over US$1 billion. Endo was awarded the 2006 Japan Prize, and the Lasker-DeBakey Clinical Medical Research Award in 2008. For his "pioneering research into a new class of molecules" for "lowering cholesterol,"[sentence fragment]
What is the answer to this question: Endo received what award in 2008?
****
So... Lasker-DeBakey Clinical Medical Research Award


Article: Galicia's inhabitants are known as Galicians (Galician: galegos, Spanish: gallegos). For well over a century Galicia has grown more slowly than the rest of Spain, due largely to emigration to Latin America and to other parts of Spain. Sometimes Galicia has lost population in absolute terms. In 1857, Galicia had Spain's densest population and constituted 11.5% of the national population. As of 2007, only 6.1% of the Spanish population resides in the autonomous community. This is due to an exodus of Galician people since the 19th century, first to South America and later to Central Europe.

Question: Aside from Spain, where have Galicians emigrated to?
Ans:
Latin America
