In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: During his stay in Puerto Rico, Thompson acquired a fairly fluent, although informal and at times incorrect, use of Spanish, which he has continued throughout his career. Several early Pixies songs, including "Isla de Encanta" and "Vamos", reference his experiences in San Juan, and the lyrics are often heavily seasoned with the island's slang. The island's influence in his work is most notable in the song "Isla De Encanta", named after the island's motto, "Isla Del Encanto". Other Pixies songs drawn from his experiences there include "Vamos" (Come On Pilgrim), "Oh My Golly!", "Where Is My Mind?" (Surfer Rosa), "Crackity Jones" (Doolittle) and the B-side "Bailey's Walk". Several of his songs contain Spanish lyrics, most notably in the Pixies' first album, Come On Pilgrim, and a Spanish translation of "Evil Hearted You" by The Yardbirds. From his later works with the Pixies onwards, his use of Spanish drifted westward, reflecting places and aspects of the state of California and its culture.Thompson's lyrics are noted for their obscure references to off-beat topics such as outer space, UFOs, and The Three Stooges—the last of these being the subject of "Two Reelers", a song from Teenager of the Year. Lyrics with a focus on science fiction were particularly prominent on the later Pixies records, as well as his early solo albums. With the Catholics, his lyrics have tended towards historical topics; for example, the song "St. Francis Dam Disaster" (from Dog in the Sand) details the catastrophic collapse of the St. Francis Dam near Los Angeles in March 1928, and the All My Ghosts EP featured an account of the Humboldt County Massacre of Wiyot Indians in 1860 near Eureka, California. 
Question: What is the name of the island whose motto is, "Isla Del Encanto," after which the Pixies song is named?
Example Output: Puerto Rico.

Example Input: Passage: The film starts off with a scene from the novel Moby Dick, with a whaler on a stormy sea in the 19th century, chasing "the white whale". It turns out that the scene comes from the imagination of Dot, while she is sitting with the book. She goes out to play with Nelson the dolphin in his pool, and he teaches her how to stay underwater for long periods of time and to communicate underwater, as well as the history and evolution of sea creatures.
While they play together, Nelson hears the wail of a beached whale named "Tonga" from the local coast, and jumps out of his pool, over the cliff beside, and dives into the ocean on the other side, to check what is going on, with Dot coming along. Dot walks up on land to talk with Tonga, but becomes upset as two boys, Alex and Owen, stand and throw sand on the whale. The boys say that they only want to push the whale back to the sea. Together, they try to push Tonga back to the water, but fail. They decide to gather as many kids as possible, in order to help the whale as much as they can.
While Alex and Owen start to gather help, Dot sits beside Tonga, trying to converse. Tonga explains that her family has been killed by whalers, and she is the only survivor, but has lost the will to live. Dot explains that she and others want to help Tonga, and tries to by having Tonga placed in the same pool as Nelson to let her recover. Dot then realizes that they do not have a transport facility for a whale. Meanwhile, a crooked fishmonger becomes interested in Tonga as a possible "Fish" source. 
Question: What is the first name of the character who learns about the history and evolution of sea creatures?
Example Output: Dot.

Example Input: Passage: "Halo" was composed by Ryan Tedder, lead vocalist of OneRepublic, together with Evan "Kidd" Bogart and Beyoncé. In an interview for HitQuarters, Kidd narrated the events that led to writing the song. OneRepublic canceled their tour after Tedder had broken his Achilles tendon and had undergone surgery. The following day, the band sent Tedder to Los Angeles. There, he and Kidd were socializing when Tedder expressed his desire to write a song. Kidd was initially opposed to the idea because Tedder was supposed to be recuperating, but the pair went to Tedder's studio. During the writing sessions, singer Ray LaMontagne was the primary inspiration for "Halo". Kidd suggested they create a song in the style of LaMontagne's "Shelter" for Beyoncé and her husband Jay-Z, and proposed the title "Halo" after hearing Tedder play "angelic" chords. They wrote the song in three hours.According to Simon Cowell, owner of the music production company Syco Entertainment, Bogart and Tedder intended "Halo" for his client, singer Leona Lewis, who could not record the song because of her tight schedule. Cowell was upset that Beyoncé chose to record the song. David Balls, editor of the British media website Digital Spy, asked Tedder during an interview whether "Halo" had initially been written for Lewis. Tedder answered that he had only tentatively offered the track to Lewis, after Beyoncé waited a long time before recording it. He commented:
There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyoncé. What happened was that Beyoncé waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it". I sent it to them and they flipped on it. They loved it and instantly said they wanted to do it. I was like, "Wait, wait, wait, no, it's not free yet!". 
Question: What is the first name of the person who underwent surgery?
Example Output:
Ryan.
