Input: Alloy
Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The electrical and thermal conductivity of alloys is usually lower than that of the pure metals. The physical properties, such as density, reactivity, Young's modulus of an alloy may not differ greatly from those of its elements, but engineering properties such as tensile strength and shear strength may be substantially different from those of the constituent materials. This is sometimes a result of the sizes of the atoms in the alloy, because larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors, helping the alloy resist deformation. Sometimes alloys may exhibit marked differences in behavior even when small amounts of one element are present. For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. Some alloys are made by melting and mixing two or more metals. Bronze, an alloy of copper and tin, was the first alloy discovered, during the prehistoric period now known as the bronze age; it was harder than pure copper and originally used to make tools and weapons, but was later superseded by metals and alloys with better properties. In later times bronze has been used for ornaments, bells, statues, and bearings. Brass is an alloy made from copper and zinc.

Copper and zinc combine to make what?
Output: Brass

Input: Oklahoma City
Oklahoma City also has several major national and state highways within its city limits. Shields Boulevard (US-77) continues from E.K. Gaylord Boulevard in downtown Oklahoma City and runs south eventually connecting to I-35 near the suburb of Moore. Northwest Expressway (Oklahoma State Highway 3) runs from North Classen Boulevard in north-central Oklahoma City to the northwestern suburbs.

What boulevard turns into E.K Gaylord Boulevard?
Output: Shields Boulevard

Input: Pub
The history of pubs can be traced back to Roman taverns, through the Anglo-Saxon alehouse to the development of the modern tied house system in the 19th century.

What Roman businesses were analogous to modern day pubs?
Output: taverns

Input: Galicia (Spain)
The most important Galician fishing port is the Port of Vigo; It is one of the world's leading fishing ports, second only to Tokyo, with an annual catch worth 1,500 million euros. In 2007 the port took in 732,951 metric tons (721,375 long tons; 807,940 short tons) of fish and seafood, and about 4,000,000 metric tons (3,900,000 long tons; 4,400,000 short tons) of other cargoes. Other important ports are Ferrol, A Coruna, and the smaller ports of Marin and Vilagarcia de Arousa, as well as important recreational ports in Pontevedra and Burela. Beyond these, Galicia has 120 other organized ports.

Which Japanese fishing port is Galicia's second to?
Output:
Tokyo
