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 Lampyridae are a family of insects in the beetle order Coleoptera. They are winged beetles, commonly called fireflies or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a ``cold light'', with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers. The eastern US is home to the species Phausis reticulata, which emits a steady blue light.
 Question: is a lightning bug and a firefly the same Context: Boiling water is not recommended for use in hot-water bottles. This is due to risks of the rubber being degraded from high-temperature water, and the risk of injury in case of breakage.
 Question: do u put boiling water in a hot water bottle Context: Carbonell's dark eyelashes have been a staple topic of discussion in interviews, and both Carbonell and the producers of Lost made it clear they are not enhanced by any form of makeup. A short skit during the Lost panel at the 2009 San Diego Comic-Con International featured Carbonell allegedly applying eyeliner before throwing a Christian Bale-esque rant upon receiving the wrong color makeup from an assistant. In a season 5 episode of Lost, James ``Sawyer'' Ford refers to Carbonell's character as ``your buddy out there with the eyeliner.'' In addition, in the Psych episode ``Shawn 2.0'', Shawn Spencer makes a comment about him having ``impossibly dark eyelashes.''
 Question: does the sheriff on bates motel wear eyeliner Context: Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. The term is also used for electrical oxidation of anions on to a solid substrate, as in the formation of silver chloride on silver wire to make silver/silver-chloride electrodes. Electroplating is primarily used to change the surface properties of an object (such as abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
 Question: electroplating is done on jobs to resist corrosion Context: The portion of the marginal cost curve above its intersection with the average variable cost curve is the supply curve for a firm operating in a perfectly competitive market. (the portion of the MC curve below its intersection with the AVC curve is not part of the supply curve because a firm would not operate at price below the shutdown point) This is not true for firms operating in other market structures. For example, while a monopoly ``has'' an MC curve it does not have a supply curve. In a perfectly competitive market, a supply curve shows the quantity a seller's willing and able to supply at each price -- for each price, there is a unique quantity that would be supplied. The one-to-one relationship simply is absent in the case of a monopoly. With a monopoly, there could be an infinite number of prices associated with a given quantity. It all depends on the shape and position of the demand curve and its accompanying marginal revenue curve.
