Input: Read this: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.
Question: What requires a four-phase transmission with at least two underground wires?

Output: unanswerable

QUES: Detroit is cited as the birthplace of techno music in the early 1980s. The city also lends its name to an early and pioneering genre of electronic dance music, "Detroit techno". Featuring science fiction imagery and robotic themes, its futuristic style was greatly influenced by the geography of Detroit's urban decline and its industrial past. Prominent Detroit techno artists include Juan Atkins, Derrick May, and Kevin Saunderson. The Detroit Electronic Music Festival, now known as "Movement", occurs annually in late May on Memorial Day Weekend, and takes place in Hart Plaza. In the early years (2000-2002), this was a landmark event, boasting over a million estimated attendees annually, coming from all over the world to celebrate Techno music in the city of its birth.

Where does "Movement" take place?
What is the answer?
ANS: Hart Plaza

QUES: Mary's special position within God's purpose of salvation as "God-bearer" (Theotokos) is recognised in a number of ways by some Anglican Christians. All the member churches of the Anglican Communion affirm in the historic creeds that Jesus was born of the Virgin Mary, and celebrates the feast days of the Presentation of Christ in the Temple. This feast is called in older prayer books the Purification of the Blessed Virgin Mary on February 2. The Annunciation of our Lord to the Blessed Virgin on March 25 was from before the time of Bede until the 18th century New Year's Day in England. The Annunciation is called the "Annunciation of our Lady" in the 1662 Book of Common Prayer. Anglicans also celebrate in the Visitation of the Blessed Virgin on 31 May, though in some provinces the traditional date of July 2 is kept. The feast of the St. Mary the Virgin is observed on the traditional day of the Assumption, August 15. The Nativity of the Blessed Virgin is kept on September 8.
On what date do most Anglicans celebrate the Visitation of the Blessed Virgin?

ANS: 31 May

The most accurate timekeeping devices are atomic clocks, which are accurate to seconds in many millions of years, and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium, most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133Cs atom.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which system bases its unit of time on the properties of vibrations?
Ah, so.. unanswerable

Question: The Wagner tuba, a modified member of the horn family, appears in Richard Wagner's cycle Der Ring des Nibelungen and several other works by Strauss, Bela Bartok, and others; it has a prominent role in Anton Bruckner's Symphony No. 7 in E Major. Cornets appear in Pyotr Ilyich Tchaikovsky's ballet Swan Lake, Claude Debussy's La Mer, and several orchestral works by Hector Berlioz. Unless these instruments are played by members doubling on another instrument (for example, a trombone player changing to euphonium for a certain passage), orchestras will use freelance musicians to augment their regular rosters.
Try to answer this question if possible: What is the name of the modified member of the horn family appearing in several works by Strauss?
Answer: The Wagner tuba

Question: Although the Arenafootball2 league played its tenth season in 2009, a conference call in December 2008 resulted in enough votes from owners and cooperation from the AFLPA for the AFL to suspend the entire 2009 season in order to create "a long-term plan to improve its economic model". In doing so, the AFL became the second sports league to cancel an entire season, after the National Hockey League cancelled the 2004-05 season because of a lockout. The AFL also became the third sports league to lose its postseason (the first being Major League Baseball, which lost its postseason in 1994 because of a strike). Efforts to reformat the league's business model were placed under the leadership of Columbus Destroyers owner Jim Renacci and interim commissioner Policy.
Try to answer this question if possible: Who owned the Columbus Destroyers in 2008?
Answer:
Jim Renacci
