Here is a question about this article: Utrecht city has an active cultural life, and in the Netherlands is second only to Amsterdam. There are several theatres and theatre companies. The 1941 main city theatre was built by Dudok. Besides theatres there is a large number of cinemas including three arthouse cinemas. Utrecht is host to the international Early Music Festival (Festival Oude Muziek, for music before 1800) and the Netherlands Film Festival. The city has an important classical music hall Vredenburg (1979 by Herman Hertzberger). Its acoustics are considered among the best of the 20th-century original music halls.[citation needed] The original Vredenburg music hall has been redeveloped as part of the larger station area redevelopment plan and in 2014 has gained additional halls that allowed its merger with the rock club Tivoli and the SJU jazzpodium. There are several other venues for music throughout the city. Young musicians are educated in the conservatory, a department of the Utrecht School of the Arts. There is a specialised museum of automatically playing musical instruments.
What is the answer to this question: What is the name of the music hall
****
So... The city has an important classical music hall Vredenburg

The problem: Answer a question about this article:
In the First World War, Devonport was the headquarters of Western Approaches Command until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force. It was an important embarkation point for US troops for D-Day. The city was heavily bombed by the Luftwaffe, in a series of 59 raids known as the Plymouth Blitz. Although the dockyards were the principal targets, much of the city centre and over 3,700 houses were completely destroyed and more than 1,000 civilians lost their lives. This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II.
How many homes were totally destroyed in the Plymouth Blitz?
****
The answer: over 3,700

Problem: Please answer a question about the following article about Napoleon:
Critics argue Napoleon's true legacy must reflect the loss of status for France and needless deaths brought by his rule: historian Victor Davis Hanson writes, "After all, the military record is unquestioned17 years of wars, perhaps six million Europeans dead, France bankrupt, her overseas colonies lost." McLynn notes that, "He can be viewed as the man who set back European economic life for a generation by the dislocating impact of his wars." However, Vincent Cronin replies that such criticism relies on the flawed premise that Napoleon was responsible for the wars which bear his name, when in fact France was the victim of a series of coalitions which aimed to destroy the ideals of the Revolution.
Which historian counters criticism of Napoleon by suggesting that the wars he fought were the responsibility of enemies of the Revolution, rather than that of Napoleon?
A: Vincent Cronin

Question: Read this and answer the question

Hopkins School, a private school, was founded in 1660 and is the fifth-oldest educational institution in the United States. New Haven is home to a number of other private schools as well as public magnet schools, including Metropolitan Business Academy, High School in the Community, Hill Regional Career High School, Co-op High School, New Haven Academy, ACES Educational Center for the Arts, the Foote School and the Sound School, all of which draw students from New Haven and suburban towns. New Haven is also home to two Achievement First charter schools, Amistad Academy and Elm City College Prep, and to Common Ground, an environmental charter school.

As one of the oldest school which was founded in 1660, what is it's name?
Answer: Hopkins School

Problem: Most clothing appears to have been made of animal skins, as indicated by finds of large numbers of bone and antler pins which are ideal for fastening leather. Wool cloth and linen might have become available during the later Neolithic, as suggested by finds of perforated stones which (depending on size) may have served as spindle whorls or loom weights. The clothing worn in the Neolithic Age might be similar to that worn by Otzi the Iceman, although he was not Neolithic (since he belonged to the later Copper age).
What were perforated stones used for?
The answer is the following: spindle whorls or loom weights

Input: Article: Since the armature windings of a direct-current or universal motor are moving through a magnetic field, they have a voltage induced in them. This voltage tends to oppose the motor supply voltage and so is called "back electromotive force (emf)". The voltage is proportional to the running speed of the motor. The back emf of the motor, plus the voltage drop across the winding internal resistance and brushes, must equal the voltage at the brushes. This provides the fundamental mechanism of speed regulation in a DC motor. If the mechanical load increases, the motor slows down; a lower back emf results, and more current is drawn from the supply. This increased current provides the additional torque to balance the new load.

Now answer this question: EMP is proportional to what?

Output:
the running speed of the motor
