In 1913, Elmer McCollum discovered the first vitamins, fat-soluble vitamin A, and water-soluble vitamin B (in 1915; now known to be a complex of several water-soluble vitamins) and named vitamin C as the then-unknown substance preventing scurvy. Lafayette Mendel and Thomas Osborne also performed pioneering work on vitamins A and B. In 1919, Sir Edward Mellanby incorrectly identified rickets as a vitamin A deficiency because he could cure it in dogs with cod liver oil. In 1922, McCollum destroyed the vitamin A in cod liver oil, but found that it still cured rickets. Also in 1922, H.M. Evans and L.S. Bishop discover vitamin E as essential for rat pregnancy, originally calling it "food factor X" until 1925.
Which disease was vitamin C claimed to help prevent?
scurvy


Input: Copper
The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching. Heating this material with silica in flash smelting removes much of the iron as slag. The process exploits the greater ease of converting iron sulfides into its oxides, which in turn react with the silica to form the silicate slag, which floats on top of the heated mass. The resulting copper matte consisting of Cu2S is then roasted to convert all sulfides into oxides:

What do the sulfides convert to after the copper matte is roasted?
Output: oxides


Input: Article: While the number of cardinals was small from the times of the Roman Empire to the Renaissance, and frequently smaller than the number of recognized churches entitled to a cardinal priest, in the 16th century the College expanded markedly. In 1587, Pope Sixtus V sought to arrest this growth by fixing the maximum size of the College at 70, including 50 cardinal priests, about twice the historical number. This limit was respected until 1958, and the list of titular churches modified only on rare occasions, generally when a building fell into disrepair. When Pope John XXIII abolished the limit, he began to add new churches to the list, which Popes Paul VI and John Paul II continued to do. Today there are close to 150 titular churches, out of over 300 churches in Rome.

Now answer this question: What was the maximum number allowed per Pope Sixtus V?

Output: 70


Article: Officers may be commissioned upon graduation from the United States Air Force Academy, upon graduation from another college or university through the Air Force Reserve Officer Training Corps (AFROTC) program, or through the Air Force Officer Training School (OTS). OTS, previously located at Lackland AFB, Texas until 1993 and located at Maxwell Air Force Base in Montgomery, Alabama since 1993, in turn encompasses two separate commissioning programs: Basic Officer Training (BOT), which is for line-officer candidates of the active-duty Air Force and the U.S. Air Force Reserve; and the Academy of Military Science (AMS), which is for line-officer candidates of the Air National Guard. (The term "line officer" derives from the concept of the line of battle and refers to an officer whose role falls somewhere within the "Line of the Air", meaning combat or combat-support operations within the scope of legitimate combatants as defined by the Geneva Conventions.)

Question: Where is the OTS in the US currently located?
Ans: Maxwell Air Force Base in Montgomery, Alabama


Here is a question about this article: The city has undergone many changes to its governance over the centuries and once again became administratively independent from Hampshire County as it was made into a unitary authority in a local government reorganisation on 1 April 1997, a result of the 1992 Local Government Act. The district remains part of the Hampshire ceremonial county.
What is the answer to this question: What county did the city of Southampton become administratively independent of in April of 1997?
****
So... Hampshire County


Article: The television station, NDtv, grew from one show in 2002 to a full 24-hour channel with original programming by September 2006. WSND-FM serves the student body and larger South Bend community at 88.9 FM, offering students a chance to become involved in bringing classical music, fine arts and educational programming, and alternative rock to the airwaves. Another radio station, WVFI, began as a partner of WSND-FM. More recently, however, WVFI has been airing independently and is streamed on the Internet.

Question: Which television station finds its home at Notre Dame?
