Input: Valencia
Public transport is provided by the Ferrocarrils de la Generalitat Valenciana (FGV), which operates the Metrovalencia and other rail and bus services. The Estacio del Nord (North Station) is the main railway terminus in Valencia. A new temporary station, Estacion de Valencia-Joaquin Sorolla, has been built on land adjacent to this terminus to accommodate high speed AVE trains to and from Madrid, Barcelona, Seville and Alicante. Valencia Airport is situated 9 km (5.6 mi) west of Valencia city centre. Alicante Airport is situated about 170 km (110 mi) south of Valencia.

What group runs Valencia's public transit?
Output: Ferrocarrils de la Generalitat Valenciana

Input: Capacitor
Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.

How can electrolytic capacitors be safely used after having been stored unused for a long time?
Output: by gradually applying the operating voltage

Input: Kanye West
West's middle-class background, flamboyant fashion sense and outspokenness have additionally set him apart from other rappers. Early in his career, he was among the first rappers to publicly criticize the preponderance of homophobia in hip hop. The sales competition between rapper 50 Cent's Curtis and West's Graduation altered the direction of hip hop and helped pave the way for new rappers who did not follow the hardcore-gangster mold. Rosie Swash of The Guardian viewed the sales competition as a historical moment in hip-hop, because it "highlighted the diverging facets of hip-hop in the last decade; the former was gangsta rap for the noughties, while West was the thinking man's alternative." Rolling Stone credited West with transforming hip hop's mainstream, "establishing a style of introspective yet glossy rap [...]", and called him "as interesting and complicated a pop star as the 2000s produceda rapper who mastered, upped and moved beyond the hip-hop game, a producer who created a signature sound and then abandoned it to his imitators, a flashy, free-spending sybarite with insightful things to say about college, culture and economics, an egomaniac with more than enough artistic firepower to back it up." His 2008 album 808s & Heartbreak polarized both listeners and critics upon its release, but was commercially successful and impacted hip hop and pop stylistically, as it laid the groundwork for a new wave of artists who generally eschewed typical rap braggadocio for intimate subject matter and introspection, including Frank Ocean, The Weeknd, Drake, Future, Kid Cudi, Childish Gambino, Lil Durk, Chief Keef, and Soulja Boy. According to Ben Detrick of XXL magazine, West effectively led a new wave of artists, including Kid Cudi, Wale, Lupe Fiasco, Kidz in the Hall, and Drake, who lacked the interest or ability to rap about gunplay or drug-dealing.

Who said that Kanye West effectively led a new wave of artists that weren't only interested in rapping about gunplay or drug dealing?
Output: Ben Detrick

Input: Economy of Greece
The evolution of the Greek economy during the 19th century (a period that transformed a large part of the world because of the Industrial Revolution) has been little researched. Recent research from 2006 examines the gradual development of industry and further development of shipping in a predominantly agricultural economy, calculating an average rate of per capita GDP growth between 1833 and 1911 that was only slightly lower than that of the other Western European nations. Industrial activity, (including heavy industry like shipbuilding) was evident, mainly in Ermoupolis and Piraeus. Nonetheless, Greece faced economic hardships and defaulted on its external loans in 1826, 1843, 1860 and 1894.

What transformed a large part of the world in the 19th century?
Output:
Industrial Revolution
