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: A brief shoot at London's City Hall was filmed on 18 April 2015, while Mendes was on location. On 17 May 2015 filming took place on the Thames in London. Stunt scenes involving Craig and Seydoux on a speedboat as well as a low flying helicopter near Westminster Bridge were shot at night, with filming temporarily closing both Westminster and Lambeth Bridges. Scenes were also shot on the river near MI6's headquarters at Vauxhall Cross. The crew returned to the river less than a week later to film scenes solely set on Westminster Bridge. The London Fire Brigade was on set to simulate rain as well as monitor smoke used for filming. Craig, Seydoux, and Waltz, as well as Harris and Fiennes, were seen being filmed. Prior to this, scenes involving Fiennes were shot at a restaurant in Covent Garden. Filming then took place in Trafalgar Square. In early June, the crew, as well as Craig, Seydoux, and Waltz, returned to the Thames for a final time to continue filming scenes previously shot on the river.
Example Output: Which bridges were shut down because of filming?

Example Input: By the 20th century, Philadelphia had become known as "corrupt and contented", with a complacent population and an entrenched Republican political machine. The first major reform came in 1917 when outrage over the election-year murder of a police officer led to the shrinking of the Philadelphia City Council from two houses to just one. In July 1919, Philadelphia was one of more than 36 industrial cities nationally to suffer a race riot of ethnic whites against blacks during Red Summer, in post-World War I unrest, as recent immigrants competed with blacks for jobs. In the 1920s, the public flouting of Prohibition laws, mob violence, and police involvement in illegal activities led to the appointment of Brigadier General Smedley Butler of the U.S. Marine Corps as director of public safety, but political pressure prevented any long-term success in fighting crime and corruption.
Example Output:
Which political party controlled Philadelphia in the early 20th century?
