Example Input: The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.
Example Output: How were the Famicom controllers attached to the console?

Example Input: In 1914, advertising executive Albert Lasker obtained a large block of the club's shares and before the 1916 season assumed majority ownership of the franchise. Lasker brought in a wealthy partner, Charles Weeghman, the proprietor of a popular chain of lunch counters who had previously owned the Chicago Whales of the short-lived Federal League. As principal owners, the pair moved the club from the West Side Grounds to the much newer Weeghman Park, which had been constructed for the Whales only two years earlier, where they remain to this day. The Cubs responded by winning a pennant in the war-shortened season of 1918, where they played a part in another team's curse: the Boston Red Sox defeated Grover Cleveland Alexander's Cubs four games to two in the 1918 World Series, Boston's last Series championship until 2004.
Example Output: Who obtained a large block of the Cub's shares in 1914?

Example Input: Unsure of his future, he first contemplated returning to London to complete his studies, but decided to return to Boston as a teacher. His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. While he was working as a private tutor, one of his most famous pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. She was later to say that Bell dedicated his life to the penetration of that "inhuman silence which separates and estranges." In 1893, Keller performed the sod-breaking ceremony for the construction of the new Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf".
Example Output:
What city did Bell decide to return to?
