Q: passage: Cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide. Cold fires are difficult to observe and are uncommon in everyday life, but they are responsible for engine knock -- the undesirable, erratic, and noisy combustion of low-octane fuels in internal combustion engines.

Q: passage: Legendary for its use of Technicolor, fantasy storytelling, musical score, and memorable characters, it has become an icon of American popular culture. It was nominated for six Academy Awards, including Best Picture, but lost to Gone with the Wind.

While the film was considered a critical success upon release in August 1939, it failed to make a profit for MGM until the 1949 rerelease, earning only $3,017,000 on a $2,777,000 budget, not including promotional costs, which made it MGM's most expensive production to that time.
