Problem: Queen (band):

That year, Queen began The Works Tour, the first tour to feature keyboardist Spike Edney as an extra live musician. The tour featured nine sold-out dates in October in Bophuthatswana, South Africa, at the arena in Sun City. Upon returning to England, they were the subject of outrage, having played in South Africa during the height of apartheid and in violation of worldwide divestment efforts and a United Nations cultural boycott. The band responded to the critics by stating that they were playing music for fans in South Africa, and they also stressed that the concerts were played before integrated audiences. Queen donated to a school for the deaf and blind as a philanthropic gesture but were fined by the British Musicians' Union and placed on the United Nations' blacklisted artists.

Who fined Queen for donating to a school for the deaf and blind?

A: British Musicians' Union


Problem: It was only in the 1980s that digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission. During this time, there was also research into other forms of digital video and audio communication. Many of these technologies, such as the Media space, are not as widely used today as videoconferencing but were still an important area of research. The first dedicated systems started to appear in the market as ISDN networks were expanding throughout the world. One of the first commercial videoconferencing systems sold to companies came from PictureTel Corp., which had an Initial Public Offering in November, 1984.
What is the minimum bit rate for compressed video and audio transmission?

Answer: 128 kilobits/s


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Certain technological inventions of the period – whether of Arab or Chinese origin, or unique European innovations – were to have great influence on political and social developments, in particular gunpowder, the printing press and the compass. The introduction of gunpowder to the field of battle affected not only military organisation, but helped advance the nation state. Gutenberg's movable type printing press made possible not only the Reformation, but also a dissemination of knowledge that would lead to a gradually more egalitarian society. The compass, along with other innovations such as the cross-staff, the mariner's astrolabe, and advances in shipbuilding, enabled the navigation of the World Oceans, and the early phases of colonialism. Other inventions had a greater impact on everyday life, such as eyeglasses and the weight-driven clock.
Which invention with military applications helped bring about the nation state?
A: gunpowder


Context and question: A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole. In absence of such current reversal, the motor would brake to a stop. In light of significant advances in the past few decades due to improved technologies in electronic controller, sensorless control, induction motor, and permanent magnet motor fields, electromechanically commutated motors are increasingly being displaced by externally commutated induction and permanent-magnet motors.
What switches the input of most DC motors?
Answer: commutator


Question: However, Avicenna posited the brain as the place where reason interacts with sensation. Sensation prepares the soul to receive rational concepts from the universal Agent Intellect. The first knowledge of the flying person would be "I am," affirming his or her essence. That essence could not be the body, obviously, as the flying person has no sensation. Thus, the knowledge that "I am" is the core of a human being: the soul exists and is self-aware. Avicenna thus concluded that the idea of the self is not logically dependent on any physical thing, and that the soul should not be seen in relative terms, but as a primary given, a substance. The body is unnecessary; in relation to it, the soul is its perfection. In itself, the soul is an immaterial substance.
Is there an answer to this question: In Avicenna's work "Floating Man", what is the perimeter of a human being?

Answer: unanswerable


Question: The first department store in the Philippines is the Hoskyn's Department Store of Hoskyn & Co. established in 1877 in Iloilo by the Englishman Henry Hoskyn, nephew of Nicholas Loney, the first British vice-consul in Iloilo. Some of the earliest department stores in the Philippines were located in Manila as early as 1898 with the opening of the American Bazaar, which was later named Beck's. During the course of the American occupation of the Philippines, many department stores were built throughout the city, many of which were located in Escolta. Heacock's, a luxury department store, was considered as the best department store in the Orient. Other department stores included Aguinaldo's, La Puerta del Sol, Estrella del Norte, and the Crystal Arcade, all of which were destroyed during the Battle of Manila in 1945. After the war, department stores were once again alive with the establishment of Shoemart (now SM), and Rustan's. Since the foundation of these companies in the 1950s, there are now more than one hundred department stores to date. At present, due to the huge success of shopping malls, department stores in the Philippines usually are anchor tenants within malls. SM Supermalls and Robinsons Malls are two of the country's most prominent mall chains, all of which has Department Store sections.
Is there an answer to this question: When was the last department store in the Philippines opened?
