Task: Question Generation
Input (English): Background Paragraph: Our knowledge of electromagnets developed from a series of observations. In 1820, Hans Oersted discovered that a current-carrying wire produced a magnetic field. Later in the same year, André-Marie Ampere discovered that a coil of wire acted like a permanent magnet and François Arago found that an iron bar could be magnetized by putting it inside of a coil of current-carrying wire. Finally, William Sturgeon found that leaving the iron bar inside the coil greatly increased the magnetic field. 
Story: Kelsey is bored in class, and sees a coil of wire with electricity running through it. There is a box of random pieces of iron on the teacher's desk so she goes and picks up two of them. Piece A she simply puts on her desk to use later, and Piece B she slowly passes through the coil of wire.
Output (English): Which piece of iron is more magnetized?
