Input: Read this: 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.
Question: What are the layers of semiconductor in a BJT?

Output: an emitter, a base, and a collector

QUES: Translations of sung textswhether of the above type meant to be sung or of a more or less literal type meant to be readare also used as aids to audiences, singers and conductors, when a work is being sung in a language not known to them. The most familiar types are translations presented as subtitles or surtitles projected during opera performances, those inserted into concert programs, and those that accompany commercial audio CDs of vocal music. In addition, professional and amateur singers often sing works in languages they do not know (or do not know well), and translations are then used to enable them to understand the meaning of the words they are singing.

Who can translations of a sung text aid?
What is the answer?
ANS: audiences, singers and conductors

QUES: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.
What is done during recordings to help reduce unwanted sounds?

ANS: amplitude of low frequencies is reduced

On January 9, 1957, Karachay Autonomous Oblast and Chechen-Ingush Autonomous Soviet Socialist Republic were restored by Khrushchev and they were transferred from the Georgian SSR back to the Russian SFSR.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who transferred the Chechen-Ingush Autonomous Soviet Socialist Republic in 1957?
Ah, so.. Khrushchev

Question:
India: Due to concerns about pro-Tibet protests, the relay through New Delhi on April 17 was cut to just 2.3 km (less than 1.5 miles), which was shared amongst 70 runners. It concluded at the India Gate. The event was peaceful due to the public not being allowed at the relay. A total of five intended torchbearers -Kiran Bedi, Soha Ali Khan, Sachin Tendulkar, Bhaichung Bhutia and Sunil Gavaskar- withdrew from the event, citing "personal reasons", or, in Bhutia's case, explicitly wishing to "stand by the people of Tibet and their struggle" and protest against the PRC "crackdown" in Tibet. Indian national football captain, Baichung Bhutia refused to take part in the Indian leg of the torch relay, citing concerns over Tibet. Bhutia, who is Sikkimese, is the first athlete to refuse to run with the torch. Indian film star Aamir Khan states on his personal blog that the "Olympic Games do not belong to China" and confirms taking part in the torch relay "with a prayer in his heart for the people of Tibet, and ... for all people across the world who are victims of human rights violations". Rahul Gandhi, son of the Congress President Sonia Gandhi and scion of the Nehru-Gandhi family, also refused to carry the torch.
Try to answer this question if possible: How many runners carried the torch in New Delhi?
Answer: 70

Problem: The causes of the Franco-Prussian War are deeply rooted in the events surrounding the unification of Germany. In the aftermath of the AustroPrussian War of 1866, Prussia had annexed numerous territories and formed the North German Confederation. This new power destabilized the European balance of power established by the Congress of Vienna in 1815 after the Napoleonic Wars. Napoleon III, then the emperor of France, demanded compensations in Belgium and on the left bank of the Rhine to secure France's strategic position, which the Prussian chancellor, Otto von Bismarck, flatly refused. Prussia then turned its attention towards the south of Germany, where it sought to incorporate the southern German kingdoms, Bavaria, Wurttemberg, Baden and Hesse-Darmstadt, into a unified Prussia-dominated Germany. France was strongly opposed to any further alliance of German states, which would have significantly strengthened the Prussian military.
What are the causes of the Franco-Prussian War deeply rooted in?

Answer:
the unification of Germany
