Input: Read this: Hazards to aircraft include debris, nesting birds, and reduced friction levels due to environmental conditions such as ice, snow, or rain. Part of runway maintenance is airfield rubber removal which helps maintain friction levels. The fields must be kept clear of debris using cleaning equipment so that loose material does not become a projectile and enter an engine duct (see foreign object damage). In adverse weather conditions, ice and snow clearing equipment can be used to improve traction on the landing strip. For waiting aircraft, equipment is used to spray special deicing fluids on the wings.
Question: What is one hazard to nesting birds?

Output: unanswerable


Input: Read this: Houston has sports teams for every major professional league except the National Hockey League (NHL). The Houston Astros are a Major League Baseball (MLB) expansion team formed in 1962 (known as the "Colt .45s" until 1965) that made one World Series appearance in 2005. The Houston Rockets are a National Basketball Association (NBA) franchise based in the city since 1971. They have won two NBA Championships: in 1994 and 1995 under star players Hakeem Olajuwon, Otis Thorpe, Clyde Drexler, Vernon Maxwell, and Kenny Smith. The Houston Texans are a National Football League (NFL) expansion team formed in 2002. The Houston Dynamo are a Major League Soccer (MLS) franchise that has been based in Houston since 2006 after they won two MLS Cup titles in 2006 and 2007. The Houston Dash play in the National Women's Soccer League (NWSL). The Scrap Yard Dawgs, a women's pro softball team, is expected to play in the National Pro Fastpitch (NPF) from 2016.

Input: Read this: The photoelectric effect is the emission of electrons (called "photoelectrons") from a surface when light is shone on it. It was first observed by Alexandre Edmond Becquerel in 1839, although credit is usually reserved for Heinrich Hertz, who published the first thorough investigation in 1887. Another particularly thorough investigation was published by Philipp Lenard in 1902. Einstein's 1905 paper discussing the effect in terms of light quanta would earn him the Nobel Prize in 1921, when his predictions had been confirmed by the experimental work of Robert Andrews Millikan. The Nobel committee awarded the prize for his work on the photo-electric effect, rather than relativity, both because of a bias against purely theoretical physics not grounded in discovery or experiment, and dissent amongst its members as to the actual proof that relativity was real.
Question: What is the photoelectric effect?

Output: the emission of electrons (called "photoelectrons") from a surface when light is shone on it


Input: Read this: A genre that greatly rose in importance was that of scientific literature. Natural history in particular became increasingly popular among the upper classes. Works of natural history include René-Antoine Ferchault de Réaumur's Histoire naturelle des insectes and Jacques Gautier d'Agoty's La Myologie complète, ou description de tous les muscles du corps humain (1746). Outside ancien régime France, natural history was an important part of medicine and industry, encompassing the fields of botany, zoology, meteorology, hydrology and mineralogy. Students in Enlightenment universities and academies were taught these subjects to prepare them for careers as diverse as medicine and theology. As shown by M D Eddy, natural history in this context was a very middle class pursuit and operated as a fertile trading zone for the interdisciplinary exchange of diverse scientific ideas.
Question: Who wrote the Histoire naturelle des insectes?

Output:
René-Antoine Ferchault de Réaumur
