You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.

King Arthur really existed, but when you read the story, you will see it`s a legend, so some parts changed. The point is he really existed.
Did King Arthur really exsist?

110 Volts is nominal and may vary when measured by a voltmeter.  That said, power is supplied using sets of three separate parallel wires that you can see up on most power poles.  The very high voltage there is stepped down using a transformer to supply most houses and businesses with a usable lower voltage.  The voltage between any one of the three wires to ground in a house is 110 Volts for example to light a light bulb.  The voltage between any two wires is 220 Volts and is used for example to power a clothes dryer or kitchen range.  Houses do not use all three wires.  A machine shop may power a large motor by connecting all three wires (in a delta or Y configuration) to obtain 440 Volts.  Therefore the progression of 110, 220, and 440 Volts stems from the use of single, two and three-phase wiring circuits.  Electrical power is conducted cross-country at very high voltages using high tension lines strung in sets of three wires or phases which produces the multiple of 11 you mention.  Incidentally there may be an additional single wire above all the rest to arrest lightning strikes.
Why is the voltage ratinging always a multiple of 11 ?

Walter Payton is my personal favorite. Who knows how good he could have been if he would have played on some decent teams earlier in his career. \n\nHowever some others that might be metioned are:\n\nJim Brown - Excellent choice, can't go wrong with a Brown ;) \n\nand\n\nBarry Sanders - Best moves ever, also played on sorry teams.\n\nOne thing that works against Brown and Sanders is that they retired early, instead of stretching their careers out and maximizing their rushing yardage.\n\nAs far as a running back who flashed brilliantly for a short time.....no one burned brighter for shorter than Earl Campbell.....he was a horse....

Who is the best running back of all time?
