Problem: Please answer a question about the following article about London:
The 2011 census recorded that 2,998,264 people or 36.7% of London's population are foreign-born making London the city with the second largest immigrant population, behind New York City, in terms of absolute numbers. The table to the right shows the most common countries of birth of London residents. Note that some of the German-born population, in 18th position, are British citizens from birth born to parents serving in the British Armed Forces in Germany. With increasing industrialisation, London's population grew rapidly throughout the 19th and early 20th centuries, and it was for some time in the late 19th and early 20th centuries the most populous city in the world. Its population peaked at 8,615,245 in 1939 immediately before the outbreak of the Second World War, but had declined to 7,192,091 at the 2001 Census. However, the population then grew by just over a million between the 2001 and 2011 Censuses, to reach 8,173,941 in the latter enumeration.
London is second only to what city in terms of its foreign population?
A: New York City

Question: Read this and answer the question

An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by metallic bonding character. An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure. Zintl phases are also sometimes considered alloys depending on bond types (see also: Van Arkel-Ketelaar triangle for information on classifying bonding in binary compounds).

What is solid solution metal elements classified as?
Answer: a single phase

Problem: In The Use of Knowledge in Society (1945), Hayek argued that the price mechanism serves to share and synchronise local and personal knowledge, allowing society's members to achieve diverse, complicated ends through a principle of spontaneous self-organization. He contrasted the use of the price mechanism with central planning, arguing that the former allows for more rapid adaptation to changes in particular circumstances of time and place. Thus, he set the stage for Oliver Williamson's later contrast between markets and hierarchies as alternative co-ordination mechanisms for economic transactions. He used the term catallaxy to describe a "self-organizing system of voluntary co-operation". Hayek's research into this argument was specifically cited by the Nobel Committee in its press release awarding Hayek the Nobel prize.
Which type of economy did Hayek believe the price mechanism to be less effective with?
The answer is the following: central planning

In 1945, the British entrepreneur J. Arthur Rank, hoping to expand his American presence, bought into a four-way merger with Universal, the independent company International Pictures, and producer Kenneth Young. The new combine, United World Pictures, was a failure and was dissolved within one year. Rank and International remained interested in Universal, however, culminating in the studio's reorganization as Universal-International. William Goetz, a founder of International, was made head of production at the renamed Universal-International Pictures Inc., which also served as an import-export subsidiary, and copyright holder for the production arm's films. Goetz, a son-in-law of Louis B. Mayer decided to bring "prestige" to the new company. He stopped the studio's low-budget production of B movies, serials and curtailed Universal's horror and "Arabian Nights" cycles. Distribution and copyright control remained under the name of Universal Pictures Company Inc.
In what year was United World Pictures founded?
1945

Input: Tucson, Arizona
The Tucson Padres played at Kino Veterans Memorial Stadium from 2011 to 2013. They served as the AAA affiliate of the San Diego Padres. The team, formerly known as the Portland Beavers, was temporarily relocated to Tucson from Portland while awaiting the building of a new stadium in Escondido. Legal issues derailed the plans to build the Escondido stadium, so they moved to El Paso, Texas for the 2014 season. Previously, the Tucson Sidewinders, a triple-A affiliate of the Arizona Diamondbacks, won the Pacific Coast League championship and unofficial AAA championship in 2006. The Sidewinders played in Tucson Electric Park and were in the Pacific Conference South of the PCL. The Sidewinders were sold in 2007 and moved to Reno, Nevada after the 2008 season. They now compete as the Reno Aces.

Where did the Padres move when the Escondido stadium fell through?
Output: El Paso, Texas

Problem: Please answer a question about the following article about Mandolin:
Much of mandolin development revolved around the soundboard (the top). Pre-mandolin instruments were quiet instruments, strung with as many as six courses of gut strings, and were plucked with the fingers or with a quill. However, modern instruments are louderusing four courses of metal strings, which exert more pressure than the gut strings. The modern soundboard is designed to withstand the pressure of metal strings that would break earlier instruments. The soundboard comes in many shapesbut generally round or teardrop-shaped, sometimes with scrolls or other projections. There is usually one or more sound holes in the soundboard, either round, oval, or shaped like a calligraphic F (f-hole). A round or oval sound hole may be covered or bordered with decorative rosettes or purfling.
Were premandolins quiet or loud instruments?
A:
quiet instruments
