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: The knockout stage of the 2018 FIFA World Cup was the second and final stage of the competition, following the group stage. It began on 30 June with the round of 16 and ended on 15 July with the final match, held at the Luzhniki Stadium in Moscow. The top two teams from each group (16 in total) advanced to the knockout stage to compete in a single-elimination style tournament. A third place play-off was also played between the two losing teams of the semi-finals.
 Question: is the round of 16 single elimination in world cup Context: The common blackbird of the nominate subspecies T. m. merula is 23.5 to 29 centimetres (9.25 to 11.4 in) in length, has a long tail, and weighs 80--125 grams (2.8 to 4.4 oz). The adult male has glossy black plumage, blackish-brown legs, a yellow eye-ring and an orange-yellow bill. The bill darkens somewhat in winter. The adult female is sooty-brown with a dull yellowish-brownish bill, a brownish-white throat and some weak mottling on the breast. The juvenile is similar to the female, but has pale spots on the upperparts, and the very young juvenile also has a speckled breast. Young birds vary in the shade of brown, with darker birds presumably males. The first year male resembles the adult male, but has a dark bill and weaker eye ring, and its folded wing is brown, rather than black like the body plumage.
 Question: does a female blackbird have a yellow beak Context: Offside is one of the laws of association football, codified in Law 11 of the Laws of the Game. The law states that a player is in an offside position if any of their body parts except the hands and arms is in the opponents' half of the pitch and closer to the opponents' goal line than both the ball and the second-last opponent (the last opponent is usually but not necessarily the goalkeeper).
 Question: does your whole body have to be offside Context: The Toronto Raptors are a Canadian professional basketball team based in Toronto, Ontario. The Raptors compete in the National Basketball Association (NBA), as a member club of the league's Eastern Conference Atlantic Division. The team was established in 1995, along with the Vancouver Grizzlies, as part of the NBA's expansion into Canada. After the Grizzlies relocated to Memphis to become the Memphis Grizzlies in 2001, the Raptors became the only Canadian-based team in the NBA. They originally played their home games at SkyDome (later renamed Rogers Centre in 2005), before moving to the Scotiabank Arena (originally named the Air Canada Centre) in 1999.
 Question: are the raptors the only canadian nba team Context: Restriction enzymes are endonucleases from eubacteria and archaea that recognize a specific DNA sequence. The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site. Typically, a restriction site will be a palindromic sequence about four to six nucleotides long. Most restriction endonucleases cleave the DNA strand unevenly, leaving complementary single-stranded ends. These ends can reconnect through hybridization and are termed ``sticky ends''. Once paired, the phosphodiester bonds of the fragments can be joined by DNA ligase. There are hundreds of restriction endonucleases known, each attacking a different restriction site. The DNA fragments cleaved by the same endonuclease can be joined together regardless of the origin of the DNA. Such DNA is called recombinant DNA; DNA formed by the joining of genes into new combinations. Restriction endonucleases (restriction enzymes) are divided into three categories, Type I, Type II, and Type III, according to their mechanism of action. These enzymes are often used in genetic engineering to make recombinant DNA for introduction into bacterial, plant, or animal cells, as well as in synthetic biology.
