Input: Read this: The first known European explorer to reach Bermuda was Spanish sea captain Juan de Bermudez in 1503, after whom the islands are named. He claimed the apparently uninhabited islands for the Spanish Empire. Paying two visits to the archipelago, Bermudez never landed on the islands, but did create a recognisable map of the archipelago. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription in Portuguese Rock (previously called Spanish Rock). Subsequent Spanish or other European parties are believed to have released pigs there, which had become feral and abundant on the island by the time European settlement began. In 1609, the English Virginia Company, which had established Jamestown in Virginia (a term originally applied to all of the North American continent) two years earlier, permanently settled Bermuda in the aftermath of a hurricane, when the crew and passengers of the Sea Venture steered the ship onto the surrounding reef to prevent its sinking, then landed ashore.

Input: Read this: Baptism is a requirement for being considered a member of Jehovah's Witnesses. Jehovah's Witnesses do not practice infant baptism, and previous baptisms performed by other denominations are not considered valid. Individuals undergoing baptism must affirm publicly that dedication and baptism identify them "as one of Jehovah's Witnesses in association with God's spirit-directed organization," though Witness publications say baptism symbolizes personal dedication to God and not "to a man, work or organization." Their literature emphasizes the need for members to be obedient and loyal to Jehovah and to "his organization,"[note 2] stating that individuals must remain part of it to receive God's favor and to survive Armageddon.
Question: What is the name of one of the Jehovah's Witnesses publications?

Output: unanswerable

Input: Read this: Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.
Question: Why didn't the companies circumvent the authentication system?

Output: unanswerable

Input: Read this: International friendlies give team managers the opportunity to experiment with team selection and tactics before the tournament proper, and also allow them to assess the abilities of players they may potentially select for the tournament squad. Players can be booked in international friendlies, and can be suspended from future international matches based on red cards or accumulated yellows in a specified period. Caps and goals scored also count towards a player's career records. In 2004, FIFA ruled that substitutions by a team be limited to six per match in international friendlies, in response to criticism that such matches were becoming increasingly farcical with managers making as many as 11 substitutions per match.
Question: What do friendlies allow managers to experiment with?

Output:
team selection and tactics
