Input: John Kerry
Alexandra was born days before Kerry began law school. In 1982, Julia asked Kerry for a separation while she was suffering from severe depression. They were divorced on July 25, 1988, and the marriage was formally annulled in 1997. "After 14 years as a political wife, I associated politics only with anger, fear and loneliness" she wrote in A Change of Heart, her book about depression. Thorne later married Richard Charlesworth, an architect, and moved to Bozeman, Montana, where she became active in local environmental groups such as the Greater Yellowstone Coalition. Thorne supported Kerry's 2004 presidential run. She died of cancer on April 27, 2006.

When did Kerry and his wife divorce?
Output: July 25, 1988

Input: Electric motor
Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s. The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Ampère's force law, was discovered later by André-Marie Ampère in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century.

Who discovered the principles of magnetic and electric interactions?
Output: André-Marie Ampère

Input: YouTube
During the same court battle, Viacom won a court ruling requiring YouTube to hand over 12 terabytes of data detailing the viewing habits of every user who has watched videos on the site. The decision was criticized by the Electronic Frontier Foundation, which called the court ruling "a setback to privacy rights". In June 2010, Viacom's lawsuit against Google was rejected in a summary judgment, with U.S. federal Judge Louis L. Stanton stating that Google was protected by provisions of the Digital Millennium Copyright Act. Viacom announced its intention to appeal the ruling.

Who was the residing judge of the lawsuit?
Output: Louis L. Stanton

Input: Gramophone record
It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.

Was it common to hear electric recordings on phonographs?
Output:
not unusual
