Input: Read this: 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, Ampere's force law, was discovered later by Andre-Marie Ampere 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.
Question: In what year did Faraday convert electrical energy into mechanical energy?

Output: 1821

Input: Read this: Prussia emerged from the war as a great power whose importance could no longer be challenged. Frederick the Great's personal reputation was enormously enhanced, as his debt to fortune (Russia's volte-face after Elizabeth's death) and to the British subsidy were soon forgotten while the memory of his energy and his military genius was strenuously kept alive. Russia, on the other hand, made one great invisible gain from the war: the elimination of French influence in Poland. The First Partition of Poland (1772) was to be a Russo-Prussian transaction, with Austria only reluctantly involved and with France simply ignored.
Question: What was the general opinion of Frederick the Great military acumen?

Output: his military genius was strenuously kept alive

Input: Read this: The only indigenous mammals of Bermuda are five species of bats, all of which are also found in the eastern United States: Lasionycteris noctivagans, Lasiurus borealis, Lasiurus cinereus, Lasiurus seminolus and Perimyotis subflavus. Other commonly known fauna of Bermuda include its national bird, the Bermuda petrel or cahow. It was rediscovered in 1951 after having been thought extinct since the 1620s. It is important as an example of a Lazarus species. The government has a programme to protect it, including restoration of a habitat area. The Bermuda rock skink was long thought to have been the only indigenous land vertebrate of Bermuda, discounting the marine turtles that lay their eggs on its beaches. Recently through genetic DNA studies, scientists have discovered that a species of turtle, the diamondback terrapin, previously thought to have been introduced, pre-dated the arrival of humans in the archipelago. As this species spends most of its time in brackish ponds, some question whether it should be classified as a land vertebrate to compete with the skink's unique status.
Question: What is the national bird of Bermuda?

Output: Bermuda petrel or cahow

Input: Read this: Central Tucson is bicycle-friendly. To the east of the University of Arizona, Third Street is bike-only except for local traffic and passes by the historic homes of the Sam Hughes neighborhood. To the west, E. University Boulevard leads to the Fourth Avenue Shopping District. To the North, N. Mountain Avenue has a full bike-only lane for half of the 3.5 miles (5.6 km) to the Rillito River Park bike and walk multi-use path. To the south, N. Highland Avenue leads to the Barraza-Aviation Parkway bicycle path.
Question: How long does N Mountain Ave have a bike lane?

Output:
half of the 3.5 miles (5.6 km) to the Rillito River Park
