Input: Zinc
Zinc is an essential mineral perceived by the public today as being of "exceptional biologic and public health importance", especially regarding prenatal and postnatal development. Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children it causes growth retardation, delayed sexual maturation, infection susceptibility, and diarrhea. Enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc can cause ataxia, lethargy and copper deficiency.

How many people are affected by zinc deficiency?
Output: two billion

Input: Airport
Airports are divided into landside and airside areas. Landside areas include parking lots, public transportation train stations and access roads. Airside areas include all areas accessible to aircraft, including runways, taxiways and aprons. Access from landside areas to airside areas is tightly controlled at most airports. Passengers on commercial flights access airside areas through terminals, where they can purchase tickets, clear security check, or claim luggage and board aircraft through gates. The waiting areas which provide passenger access to aircraft are typically called concourses, although this term is often used interchangeably with terminal.

Where can passengers purchase tickets?
Output: terminals

Input: Richard Feynman
After the success of quantum electrodynamics, Feynman turned to quantum gravity. By analogy with the photon, which has spin 1, he investigated the consequences of a free massless spin 2 field, and derived the Einstein field equation of general relativity, but little more. The computational device that Feynman discovered then for gravity, "ghosts", which are "particles" in the interior of his diagrams that have the "wrong" connection between spin and statistics, have proved invaluable in explaining the quantum particle behavior of the YangMills theories, for example, QCD and the electro-weak theory.

What equation did Feyman derive?
Output: Einstein field equation of general relativity

Input: Cyprus
Greek Cypriots and Turkish Cypriots share a lot in common in their culture but also have differences. Several traditional food (such as souvla and halloumi) and beverages are similar, as well as expressions and ways of life. Hospitality and buying or offering food and drinks for guests or others are common among both. In both communities, music, dance and art are integral parts of social life and many artistic, verbal and nonverbal expressions, traditional dances such as tsifteteli, similarities in dance costumes and importance placed on social activities are shared between the communities. However, the two communities have distinct religions and religious cultures, with the Greek Cypriots traditionally being Greek Orthodox and Turkish Cypriots traditionally being Sunni Muslims, which has partly hindered cultural exchange. Greek Cypriots have influences from Greece and Christianity, while Turkish Cypriots have influences from Turkey and Islam.

What religion do Greek Cypriots usually practice?
Output:
Greek Orthodox
