Problem: New Haven, Connecticut:

New Haven has many architectural landmarks dating from every important time period and architectural style in American history. The city has been home to a number of architects and architectural firms that have left their mark on the city including Ithiel Town and Henry Austin in the 19th century and Cesar Pelli, Warren Platner, Kevin Roche, Herbert Newman and Barry Svigals in the 20th. The Yale School of Architecture has fostered this important component of the city's economy. Cass Gilbert, of the Beaux-Arts school, designed New Haven's Union Station and the New Haven Free Public Library and was also commissioned for a City Beautiful plan in 1919. Frank Lloyd Wright, Marcel Breuer, Alexander Jackson Davis, Philip C. Johnson, Gordon Bunshaft, Louis Kahn, James Gamble Rogers, Frank Gehry, Charles Willard Moore, Stefan Behnisch, James Polshek, Paul Rudolph, Eero Saarinen and Robert Venturi all have designed buildings in New Haven. Yale's 1950s-era Ingalls Rink, designed by Eero Saarinen, was included on the America's Favorite Architecture list created in 2007.

What division of Yale University is credited with nurturing the architectural component of New Havens economy?

A: The Yale School of Architecture

Problem: Hayek's influence on the development of economics is widely acknowledged. Hayek is the second-most frequently cited economist (after Kenneth Arrow) in the Nobel lectures of the prize winners in economics, which is particularly striking since his own lecture was critical of the field of orthodox economics and neo-classical modelisation. A number of Nobel Laureates in economics, such as Vernon Smith and Herbert A. Simon, recognise Hayek as the greatest modern economist. Another Nobel winner, Paul Samuelson, believed that Hayek was worthy of his award but nevertheless claimed that "there were good historical reasons for fading memories of Hayek within the mainstream last half of the twentieth century economist fraternity. In 1931, Hayek's Prices and Production had enjoyed an ultra-short Byronic success. In retrospect hindsight tells us that its mumbo-jumbo about the period of production grossly misdiagnosed the macroeconomics of the 19271931 (and the 19312007) historical scene". Despite this comment, Samuelson spent the last 50 years of his life obsessed with the problems of capital theory identified by Hayek and Bohm-Bawerk, and Samuelson flatly judged Hayek to have been right and his own teacher, Joseph Schumpeter, to have been wrong on the central economic question of the 20th century, the feasibility of socialist economic planning in a production goods dominated economy.
Which economist is cited the most by winners of the Nobel prize in that field?

Answer: Kenneth Arrow

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
BJTs have three terminals, corresponding to the three layers of semiconductoran emitter, a base, and a collector. They are useful in amplifiers because the currents at the emitter and collector are controllable by a relatively small base current. In an npn transistor operating in the active region, the emitterbase junction is forward biased (electrons and holes recombine at the junction), and electrons are injected into the base region. Because the base is narrow, most of these electrons will diffuse into the reverse-biased (electrons and holes are formed at, and move away from the junction) basecollector junction and be swept into the collector; perhaps one-hundredth of the electrons will recombine in the base, which is the dominant mechanism in the base current. By controlling the number of electrons that can leave the base, the number of electrons entering the collector can be controlled. Collector current is approximately (common-emitter current gain) times the base current. It is typically greater than 100 for small-signal transistors but can be smaller in transistors designed for high-power applications.
How many electrons are injected into the base region?
A: unanswerable

Context and question: In 1454 King Casimir IV granted the Nieszawa Statutes (Polish: "statuty cerkwicko-nieszawskie"), clarifying the legal basis of voivodship sejmiks (local parliaments). The king could promulgate new laws, raise taxes, or call for a levee en masse (pospolite ruszenie) only with the consent of the sejmiks, and the nobility were protected from judicial abuses. The Nieszawa Statutes also curbed the power of the magnates, as the Sejm (national parliament) received the right to elect many officials, including judges, voivods and castellans. These privileges were demanded by the szlachta as a compensation for their participation in the Thirteen Years' War.
Why did the szlachta demand privileges?
Answer: their participation in the Thirteen Years' War.

Question: Community Training Centres (CTCs) have been established within the primary schools on each atoll. The CTCs provide vocational training to students who do not progress beyond Class 8 because they failed the entry qualifications for secondary education. The CTCs offer training in basic carpentry, gardening and farming, sewing and cooking. At the end of their studies the graduates can apply to continue studies either at Motufoua Secondary School or the Tuvalu Maritime Training Institute (TMTI). Adults can also attend courses at the CTCs.
Is there an answer to this question: What from of education do Community Training Centres provide?

Answer: vocational training

Question: There are occasional brief hints and allusions in his longer works however that Avicenna considered philosophy as the only sensible way to distinguish real prophecy from illusion. He did not state this more clearly because of the political implications of such a theory, if prophecy could be questioned, and also because most of the time he was writing shorter works which concentrated on explaining his theories on philosophy and theology clearly, without digressing to consider epistemological matters which could only be properly considered by other philosophers.
Is there an answer to this question: What did Avicenna fear about stating his theories on biology more clearly?

Answer:
unanswerable
