TASK DEFINITION: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
PROBLEM: passage: During the 19th century many of the smaller German and Italian states were ruled by Dukes or Grand Dukes. But at present, with the exception of the Grand Duchy of Luxembourg, there are no dukes ruling as monarchs. Duke remains the highest hereditary title (aside from titles borne by the reigning or formerly reigning dynasty) in Portugal (though now a republic), Spain, and the United Kingdom. In Sweden, members of the Royal Family are given a personal dukedom at birth. The Pope, as a temporal sovereign, has also, though rarely, granted the title of Duke or Duchess to persons for ''services'' to the Holy See. In some realms the relative status of ''duke'' and ''prince'', as titles borne by the nobility rather than by members of reigning dynasties, varied--e.g., in Italy and the Netherlands.
question: do you have to be married to be a duke?

SOLUTION: No

PROBLEM: passage: Damon Salvatore is a fictional character in The Vampire Diaries novel series. He is portrayed by Ian Somerhalder in the television series. Initially, Damon is the main antagonist in the beginning of the show and later became a protagonist. After the first few episodes, Damon begins working alongside his younger brother, Stefan Salvatore, to resist greater threats and gradually Elena begins to consider him a friend. His transition was completed after his younger brother Stefan, who is also a vampire, convinces him to drink blood. Damon thus vows to make his brother's life sorrowful -- thus further causing a century-long rift between the two brothers, centering around Katherine and eventually a love triangle with Elena Gilbert. After on-again/off-again relationship with both brothers, Elena chooses to be with Damon in the series finale.
