Input: Read this: Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.
Question: What do hysteresis synchronous motors' rotors do when slip rate decreases?

Output: becomes temporarily magnetized


QUES: The climate in Southeast Alaska is a mid-latitude oceanic climate (Köppen climate classification: Cfb) in the southern sections and a subarctic oceanic climate (Köppen Cfc) in the northern parts. On an annual basis, Southeast is both the wettest and warmest part of Alaska with milder temperatures in the winter and high precipitation throughout the year. Juneau averages over 50 in (130 cm) of precipitation a year, and Ketchikan averages over 150 in (380 cm). This is also the only region in Alaska in which the average daytime high temperature is above freezing during the winter months.

How much precipitation does Juneau receive each month?

QUES: During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.

In its 2011 report, conducted in partnership with IDC and Ipsos Public Affairs, the BSA stated: "Over half of the world's personal computer users – 57 percent – admit to pirating software." The ninth annual "BSA Global Software Piracy Study" claims that the "commercial value of this shadow market of pirated software" was worth US$63.4 billion in 2011, with the highest commercial value of pirated PC software existent in the U.S. during that time period (US$9,773,000). According to the 2011 study, Zimbabwe was the nation with the highest piracy rate, at 92%, while the lowest piracy rate was present in the U.S., at 19%.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who else did the BSA issues a report in 2011 with?
Ah, so.. IDC and Ipsos Public Affairs


Question: At the beginning of World War I, East Prussia became a theatre of war when the Russian Empire invaded the country. The Russian Army encountered at first little resistance because the bulk of the German Army had been directed towards the Western Front according to the Schlieffen Plan. Despite early success and the capture of the towns of Rastenburg and Gumbinnen, in the Battle of Tannenberg in 1914 and the Second Battle of the Masurian Lakes in 1915, the Russians were decisively defeated and forced to retreat. The Russians were followed by the German Army advancing into Russian territory.
Try to answer this question if possible: In what year was the First Battle of the Masurian Lakes?
Answer: unanswerable


Context and question: Greece has tended to lag behind its European Union partners in terms of Internet use, with the gap closing rapidly in recent years. The percentage of households with access to the Internet more than doubled between 2006 and 2013, from 23% to 56% respectively (compared with an EU average of 49% and 79%). At the same time, there has been a massive increase in the proportion of households with a broadband connection, from 4% in 2006 to 55% in 2013 (compared with an EU average of 30% and 76%). However, Greece also has the EU's third highest percentage of people who have never used the Internet: 36% in 2013, down from 65% in 2006 (compared with an EU average of 21% and 42%).
What percentage of people in Greece have never stopped using the Internet as of 2013?
