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 poker it is sometimes necessary to split, or divide the pot among two or more players rather than awarding it all to a single player. This can happen because of ties, and also by playing intentional split-pot poker variants (the most typical of these is high-low split poker, where the high hand and low hand split the pot).
 Question: do you ever split the pot in poker Context: According to the theory of relativity, no information can travel faster than the speed of light in vacuum, but this does not mean that the refractive index cannot be lower than 1. The refractive index measures the phase velocity of light, which does not carry information. The phase velocity is the speed at which the crests of the wave move and can be faster than the speed of light in vacuum, and thereby give a refractive index below 1. This can occur close to resonance frequencies, for absorbing media, in plasmas, and for X-rays. In the X-ray regime the refractive indices are lower than but very close to 1 (exceptions close to some resonance frequencies). As an example, water has a refractive index of 6999999999740000000♠0.99999974 = 1 − 6993260000000000000♠2.6×10 for X-ray radiation at a photon energy of 6985480652946099999♠30 keV (0.04 nm wavelength).
 Question: is it possible to have a refractive index less than 1 Context: The RAAF's current VIP aircraft are two leased Boeing Business Jets and three Bombardier Challengers which are operated by No. 34 Squadron RAAF and are based at Canberra Airport. The Boeing Business Jets are custom configured Boeing 737-700s fitted with facilities such as conference tables, offices suites, secure satellite and communication capabilities. The two planes have a longer range than is standard for Boeing Business Jets. The Prime Minister regularly makes use of the aircraft for domestic and international travel.
 Question: does the australian prime minister have a plane Context: A spile is a small wooden or metal peg used to control the flow of air into, and carbon dioxide out of, a cask of ale. Spiles can also be used to broach water from trees.
 Question: can you get water from a tree with a spile Context: The original IMPs and TIPs were phased out as the ARPANET was shut down after the introduction of the NSFNet, but some IMPs remained in service as late as July 1990.
 Question: the darpanet or arpanet hardware is still in place today Context: In 1960, a Dutch version was released by Toby Rix. The song was performed by the Bee Gees on the Australian TV show Bandstand in 1963. Also in 1963, a parody version, ``My Old Man's An All-Black'', was released in New Zealand by the Howard Morrison Quartet and, in the US, the Smothers Brothers included a parody based on the song on their LP Think Ethnic. In 1966, The Irish Rovers included a version of the song on their LP The First of the Irish Rovers.
