Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: A primary school (or elementary school in American English and often in Canadian English) is a school in which children receive primary or elementary education from the age of about seven to twelve, coming after preschool , infant school and before secondary school. (In some countries there is an intermediate stage of middle school between primary and secondary education.)
 Question: is elementary school the same as primary school Context: The reciprocal of a fraction is another fraction with the numerator and denominator exchanged. The reciprocal of 3 7 (\displaystyle (\tfrac (3)(7))) , for instance, is 7 3 (\displaystyle (\tfrac (7)(3))) . The product of a fraction and its reciprocal is 1, hence the reciprocal is the multiplicative inverse of a fraction. The reciprocal of a proper fraction is improper, and the reciprocal of an improper fraction not equal to 1, that is, numerator and denominator are not equal, is a proper fraction.
 Question: will the reciprocal of a proper fraction be a proper fraction Context: The Electric Variable Transmission (EVT) combines a transmission with an electric motor to provide the illusion of a single CVT. In the common implementation, a gasoline engine is connected to a traditional transmission, which is in turn connected to an epicyclic gear system's planet carrier. An electric motor/generator is connected to the central ``sun'' gear, which is normally un-driven in typical epicyclic systems. Both sources of power can be fed into the transmission's output at the same time, splitting power between them. In common examples, between one-quarter and half of the engine's power can be fed into the sun gear. Depending on the implementation, the transmission in front of the epicyclic system may be greatly simplified, or eliminated completely. EVTs are capable of continuously modulating output/input speed ratios like mechanical CVTs, but offer the distinct benefit of being able to also apply power from two different sources to one output, as well as potentially reducing overall complexity dramatically.
 Question: is the transmission and motor the same thing Context: The official synopsis of The Boat That Rocked before release stated that it tells the fictional story about a group of DJs in 1966 who are at odds with a traditionalist British government that prefers to broadcast jazz. According to director Richard Curtis, the film, though inspired by real British pirate radio of the 1960s, is a work of historical fiction and does not depict a specific radio station of the period.
 Question: the boat that rocked is it a true story Context: The plant also contains saponins. Although deadly, the plant has been used as a folk remedy in moderate amounts, and is currently used by herbalists as a restricted herbal remedy. It also contains the unusual, poisonous amino acid azetidine-2-carboxylic acid.
