Question: On 2 December 1942, as part of the Manhattan Project, another team led by Enrico Fermi was able to initiate the first artificial self-sustained nuclear chain reaction, Chicago Pile-1. Working in a lab below the stands of Stagg Field at the University of Chicago, the team created the conditions needed for such a reaction by piling together 400 short tons (360 metric tons) of graphite, 58 short tons (53 metric tons) of uranium oxide, and six short tons (5.5 metric tons) of uranium metal, a majority of which was supplied by Westinghouse Lamp Plant in a makeshift production process.
Is there an answer to this question: On what date was the last self-sustained nuclear chain reaction created artificially?

Question: Some in the entertainment industry were critical of the star-making aspect of the show. Usher, a mentor on the show, bemoaning the loss of the "true art form of music", thought that shows like American Idol made it seem "so easy that everyone can do it, and that it can happen overnight", and that "television is a lie". Musician Michael Feinstein, while acknowledging that the show had uncovered promising performers, said that American Idol "isn't really about music. It's about all the bad aspects of the music business the arrogance of commerce, this sense of 'I know what will make this person a star; artists themselves don't know.' " That American Idol is seen to be a fast track to success for its contestants has been a cause of resentment for some in the industry. LeAnn Rimes, commenting on Carrie Underwood winning Best Female Artist in Country Music Awards over Faith Hill in 2006, said that "Carrie has not paid her dues long enough to fully deserve that award". It is a common theme that has been echoed by many others. Elton John, who had appeared as a mentor in the show but turned down an offer to be a judge on American Idol, commenting on talent shows in general, said that "there have been some good acts but the only way to sustain a career is to pay your dues in small clubs".
Is there an answer to this question: What singer criticized Carrie Underwood for winning a Country Music Award?

Answer: LeAnn Rimes

Question: The primary site of infection in the lungs, known as the "Ghon focus", is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. Tuberculosis of the lungs may also occur via infection from the blood stream. This is known as a Simon focus and is typically found in the top of the lung. This hematogenous transmission can also spread infection to more distant sites, such as peripheral lymph nodes, the kidneys, the brain, and the bones. All parts of the body can be affected by the disease, though for unknown reasons it rarely affects the heart, skeletal muscles, pancreas, or thyroid.
Is there an answer to this question: Where are the peripheral lymph nodes?

Answer: unanswerable

Question: The test game was played in Rockford, Illinois, at the Rockford MetroCentre. Sponsors were secured, and players and coaches from local colleges were recruited to volunteer to play for the teams, the Chicago Politicians and Rockford Metros, with the guarantee of a tryout should the league take off. Interest was high enough following the initial test game that Foster decided to put on a second, "showcase", game. The second game was held on February 26, 1987 at the Rosemont Horizon in Chicago with a budget of $20,000, up from $4,000 in the test game. Foster also invited ESPN to send a film crew to the game; a highlights package aired on SportsCenter.
Is there an answer to this question: The second test game was played in what arena?

Answer:
Rosemont Horizon
