question:
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.
 question: is there such a thing as cold fire?
answer:
Yes


question:
passage: Dr. Henry Jekyll feels he is battling between the good and bad within himself, thus leading to the struggle with his alter ego, Edward Hyde. He spends his life trying to repress evil urges that are not fitting for a man of his stature. He develops a serum in an attempt to mask this hidden evil. However, in doing so, Jekyll transforms into Hyde, a hideous creature without compassion or remorse. Jekyll has a friendly personality, but as Hyde, he becomes mysterious and violent. As time goes by, Hyde grows in power and eventually manifests whenever Jekyll shows signs of physical or moral weakness, no longer needing the serum to be released.

Yes
