Input: Transistor
Discrete transistors are individually packaged transistors. Transistors come in many different semiconductor packages (see image). The two main categories are through-hole (or leaded), and surface-mount, also known as surface-mount device (SMD). The ball grid array (BGA) is the latest surface-mount package (currently only for large integrated circuits). It has solder "balls" on the underside in place of leads. Because they are smaller and have shorter interconnections, SMDs have better high-frequency characteristics but lower power rating.

What is a ball grid array composed of?
Output: solder "balls" on the underside in place of leads

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 created the first electrostatic device?
Output: Andrew Gordon

Input: Zhejiang
On Thursday, September 15, 2011, more than 500 people from Hongxiao Village protested over the large-scale death of fish in a nearby river. Angry protesters stormed the Zhejiang Jinko Solar Company factory compound, overturned eight company vehicles, and destroyed the offices before police came to disperse the crowd. Protests continued on the two following nights with reports of scuffles, officials said. Chen Hongming, a deputy head of Haining's environmental protection bureau, said the factory's waste disposal had failed pollution tests since April. The environmental watchdog had warned the factory, but it had not effectively controlled the pollution, Chen added.

How many company vehicles did angry protesters overturn at the Zhejiang Jinko Solar Company?
Output: eight

Input: Westminster Abbey
Since 1066, when Harold Godwinson and William the Conqueror were crowned, the coronations of English and British monarchs have been held there. There have been at least 16 royal weddings at the abbey since 1100. Two were of reigning monarchs (Henry I and Richard II), although, before 1919, there had been none for some 500 years.

How many royal weddings have occurred at the abbey?
Output:
16
