Example Input: Devonport Dockyard is the UK's only naval base that refits nuclear submarines and the Navy estimates that the Dockyard generates about 10% of Plymouth's income. Plymouth has the largest cluster of marine and maritime businesses in the south west with 270 firms operating within the sector. Other substantial employers include the university with almost 3,000 staff, as well as the Tamar Science Park employing 500 people in 50 companies. Several employers have chosen to locate their headquarters in Plymouth, including Hemsley Fraser.
Example Output: About what percentage of Plymouth's income comes from the Dockyard?

Example Input: In 1955, the diaries of Napoleon's valet, Louis Marchand, were published. His description of Napoleon in the months before his death led Sten Forshufvud in a 1961 paper in Nature to put forward other causes for his death, including deliberate arsenic poisoning. Arsenic was used as a poison during the era because it was undetectable when administered over a long period. Forshufvud, in a 1978 book with Ben Weider, noted that Napoleon's body was found to be remarkably well preserved when moved in 1840. Arsenic is a strong preservative, and therefore this supported the poisoning hypothesis. Forshufvud and Weider observed that Napoleon had attempted to quench abnormal thirst by drinking large amounts of orgeat syrup that contained cyanide compounds in the almonds used for flavouring.
Example Output: When were the diaries of Napoleon's valet published?

Example Input: The basic MP3 decoding and encoding technology is patent-free in the European Union, all patents having expired there. In the United States, the technology will be substantially patent-free on 31 December 2017 (see below). The majority of MP3 patents expired in the US between 2007 and 2015.
Example Output:
Where is the basic MP3 decoding and technology patent free?
