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: Hundreds of large trees are topped each year, which causes significant stress and future safety issues. It has been shown through survey that the average person's knowledge on tree care is limited.
 Question: does cutting the top of a tree kill it Context: An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.
 Question: is it possible for a triangle to have two obtuse angles Context: In 1993, GM released new Dexron-III fluid (GM Spec GM6417M and later GMN10055). It is generally backward-compatible with transmissions using earlier Dexron fluids or Type-A/Suffix-A fluid. However this specification failed to address a number of issues concerning long term durability such as shear stability and fluid oxidation. Dexron-III underwent a number of iterations in an attempt to address various shortcomings but was eventually replaced by new thinking i.e. DEXRON-VI.
 Question: can i use dexron iii for dexron ii Context: The NFL's cap is a hard cap that the teams have to stay under at all times, and the salary floor is also a hard floor. Penalties for violating or circumventing the cap regulations include fines of up to $5 million for each violation, cancellation of contracts and/or loss of draft picks. Violating the salary floor regulations does not result in any fines or competitive penalties; instead, deficiencies are placed into a pool and distributed among all players who were on the regular roster of the offending team during a four-year floor cycle, prorated according to time on the roster in said period.
 Question: does each nfl team have the same salary cap Context: Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.
 Question: can a woman produce twins of different fathers Context: A sheep--goat hybrid (called a geep in popular media or sometimes a shoat) is the hybrid offspring of a sheep and a goat. Although sheep and goats seem similar and can be mated, they belong to different genera in the subfamily Caprinae of the family Bovidae. Sheep belong to the genus Ovis and have 54 chromosomes, while goats belong to the genus Capra and have 60 chromosomes. The offspring of a sheep-goat pairing is generally stillborn. Despite widespread shared pasturing of goats and sheep, hybrids are very rare, indicating the genetic distance between the two species. Though sometimes called ``geep'', they are not to be confused with sheep--goat chimera, which are artificially created by combining the embryos of a goat and a sheep.
