Example Input: Passage: Wyatt Frame, an executive with the pop music record label MegaRecords, is confronted on a private jet by boy band DuJour over a strange backing track they discovered on their recent single. Wyatt and the plane's pilot parachute out of the jet, leaving it to crash and "kill" the band. 
Wyatt lands outside of the town of Riverdale, and begins searching for a band to replace DuJour. He discovers struggling local rock band The Pussycats: lead vocalist and guitarist Josie McCoy, drummer Melody Valentine, and bassist Valerie Brown. The group accept Wyatt's immediate offer of a major record deal despite its seeming implausibility, and are flown to New York City with their manager Alexander, his sister Alexandra, and Josie's friend Alan M. The group is rebranded "Josie and the Pussycats", to Valerie's chagrin.
Meanwhile, MegaRecords CEO Fiona meets with world government representatives. She details how the United States government has conspired with the music industry to add subliminal messages as backing tracks to pop music to brainwash teenagers into buying consumer products. The government theorizes that the economy can be stimulated by channeling the disposable income of young people into trendy and expensive goods; music artists who discover the truth are "killed".
The band's first single is released, and due to subliminal messaging, is an instant success. Valerie begins to resent the attention the label gives Josie, while Melody's uncanny behavioral perception makes her suspicious of Fiona. Fiona orders Wyatt to kill Valerie and Melody before they uncover the conspiracy; they are sent to a fake appearance on Total Request Live where Carson Daly attempts to kill them, though they survive due to his incompetence. 
Question: Who discovered a strange backing track on their recent single?
Example Output: DuJour.

Example Input: Passage: "Freedom of the seas" is a principle in international law dating from the seventeenth century. It stresses freedom to navigate the oceans and disapproves of war fought in international waters. Today, this concept is enshrined in the United Nations Convention on the Law of the Sea (UNCLOS), the third version of which came into force in 1994. Article 87(1) states: "The high seas are open to all states, whether coastal or land-locked." Article 87(1) (a) to (f) gives a non-exhaustive list of freedoms including navigation, overflight, the laying of submarine cables, building artificial islands, fishing and scientific research. The safety of shipping is regulated by the International Maritime Organization. Its objectives include developing and maintaining a regulatory framework for shipping, maritime safety, environmental concerns, legal matters, technical co-operation and maritime security.UNCLOS defines various areas of water. "Internal waters" are on the landward side of a baseline and foreign vessels have no right of passage in these. "Territorial waters" extend to 12 nautical miles (22 kilometres; 14 miles) from the coastline and in these waters, the coastal state is free to set laws, regulate use and exploit any resource. A "contiguous zone" extending a further 12 nautical miles allows for hot pursuit of vessels suspected of infringing laws in four specific areas: customs, taxation, immigration and pollution. An "exclusive economic zone" extends for 200 nautical miles (370 kilometres; 230 miles) from the baseline. Within this area, the coastal nation has sole exploitation rights over all natural resources. The "continental shelf" is the natural prolongation of the land territory to the continental margin's outer edge, or 200 nautical miles from the coastal state's baseline, whichever is greater. Here the coastal nation has the exclusive right to harvest minerals and also living resources "attached" to the seabed. 
Question: How many kilometres does the does the coastal nation have sole exploitation rights over natural resources?
Example Output:
370 kilometres.
