Input: Read this: J. Barrie Jones suggests that "amongst the works that Chopin intended for concert use, the four ballades and four scherzos stand supreme", and adds that "the Barcarolle Op. 60 stands apart as an example of Chopin's rich harmonic palette coupled with an Italianate warmth of melody." Temperley opines that these works, which contain "immense variety of mood, thematic material and structural detail", are based on an extended "departure and return" form; "the more the middle section is extended, and the further it departs in key, mood and theme, from the opening idea, the more important and dramatic is the reprise when it at last comes."
Question: What piece does J. Barrie Jones pinpoint as a great example of Chopin's palette?

Output: the Barcarolle Op. 60

Input: Read this: In 2001, Fuller, Cowell, and TV producer Simon Jones attempted to sell the Pop Idol format to the United States, but the idea was met with poor response from United States television networks. However, Rupert Murdoch, head of Fox's parent company, was persuaded to buy the show by his daughter Elisabeth, who was a fan of the British show. The show was renamed American Idol: The Search for a Superstar and debuted in the summer of 2002. Cowell was initially offered the job as showrunner but refused; Lythgoe then took over that position. Much to Cowell's surprise, it became one of the hit shows for the summer that year. The show, with the personal engagement of the viewers with the contestants through voting, and the presence of the acid-tongued Cowell as a judge, grew into a phenomenon. By 2004, it had become the most-watched show in the U.S., a position it then held on for seven consecutive seasons.
Question: Who talked Rupert Murdoch into buying American Idol for FOX?

Output:
his daughter Elisabeth
