Here is a question about this article: The eligible age-range for contestants is currently fifteen to twenty-eight years old. The initial age limit was sixteen to twenty-four in the first three seasons, but the upper limit was raised to twenty-eight in season four, and the lower limit was reduced to fifteen in season ten. The contestants must be legal U.S. residents, cannot have advanced to particular stages of the competition in previous seasons (varies depending on the season, currently by the semi-final stage until season thirteen), and must not hold any current recording or talent representation contract by the semi-final stage (in previous years by the audition stage).
What is the answer to this question: When was the age limit increased to 28?
****
So... season four

Here is a question about this article: For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.
What is the answer to this question: What percentage of voltage reversal does an AC circuit experience?
****
So... 100% voltage reversal

Here is a question about this article: The following year, when Philip Graves, the Constantinople (modern Istanbul) correspondent of The Times, exposed The Protocols as a forgery, The Times retracted the editorial of the previous year.
What is the answer to this question: A Constantinople correspondent of The Times exposed what anti-Semitic document as a forgery?

So...
The Protocols
