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: In 1937, the American M1 Garand was the first semi-automatic rifle to replace its nation's bolt-action rifle as the standard-issue infantry weapon. The gas-operated M1 Garand was developed by Canadian-born John Garand for the U.S. government at the Springfield Armory in Springfield, Massachusetts. After years of research and testing, the first production model of the M1 Garand was unveiled in 1937. During World War II, the M1 Garand gave American infantrymen an advantage over their opponents, most of whom were issued slower firing bolt-action rifles.
 Question: is a bolt action rifle considered semi automatic Context: Glutinous rice (Oryza sativa var. glutinosa; also called sticky rice, sweet rice or waxy rice) is a type of rice grown mainly in Southeast and East Asia and the eastern parts of South Asia, which has opaque grains, very low amylose content, and is especially sticky when cooked. While it is widely consumed across Asia, it is only a staple food in northeastern Thailand and Laos.
 Question: is sticky rice the same as sweet rice Context: This is a list of no-hitters in Major League Baseball history. In addition, all no-hitters that were broken up in extra innings or were in shortened games are listed, although they are not currently considered official no-hitters. (Prior to 1991, a performance in which no hits were surrendered through nine innings or in a shortened game was considered an official no-hit game.) The names of those pitchers who threw a perfect game no-hitter are italicized. For combined no-hitters by two or more pitchers on the same team, each is listed with his number of innings pitched. Games which were part of a doubleheader are noted as either the first game or second game. The most recent no-hitter was pitched by Edinson Vólquez of the Miami Marlins on June 3, 2017.
 Question: has there been any no hitters in 2017 Context: John Wayne Airport (IATA: SNA, ICAO: KSNA, FAA LID: SNA) is an international airport in Orange County, California, United States, with its mailing address in the city of Santa Ana, hence the IATA airport code. The entrance to the airport is off MacArthur Blvd in Irvine, the city that borders the airport on the north and east. Newport Beach and Costa Mesa form the southern and western boundaries along with a small unincorporated area along the Corona del Mar (73) Freeway. Santa Ana is just north, not actually touching the airport. Originally named Orange County Airport, the county Board of Supervisors renamed it in 1979 to honor actor John Wayne, who lived in neighboring Newport Beach and died that year.
 Question: is santa ana the same as john wayne airport Context: The coefficient of variation (CV) is defined as the ratio of the standard deviation σ (\displaystyle \ \sigma ) to the mean μ (\displaystyle \ \mu ) : c v = σ μ . (\displaystyle c_(\rm (v))=(\frac (\sigma )(\mu )).) It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on a ratio scale, as these are the measurements that can only take non-negative values. The coefficient of variation may not have any meaning for data on an interval scale. For example, most temperature scales (e.g., Celsius, Fahrenheit etc.) are interval scales that can take both positive and negative values, whereas the Kelvin temperature can never be less than zero, which is the complete absence of thermal energy. Hence, the Kelvin scale is a ratio scale. While the standard deviation (SD) can be derived on both the Kelvin and the Celsius scale (with both leading to the same SDs), the CV is only relevant as a measure of relative variability for the Kelvin scale.
