Passage: Three years after the destruction of the Death Star, the Rebel Alliance, led by Princess Leia, has set up a new base on the ice planet of Hoth. The Imperial fleet, led by Darth Vader, continues to hunt for the new Rebel base by dispatching probe droids across the galaxy. Luke Skywalker is captured by a wampa while investigating one such probe, but manages to escape from the wampa's lair with his lightsaber. Before Luke succumbs to hypothermic sleep, the Force ghost of his late mentor, Obi-Wan Kenobi, instructs him to go to Dagobah to train under Jedi Master Yoda. Han Solo locates Luke and cuts open the tauntaun he rode there on to keep his friend warm; they wait there until being rescued by a search party the next morning.
Meanwhile, the probe alerts the Imperial fleet to the Rebels' location. The Empire launches a large-scale attack using AT-AT walkers to capture the base, which forces the Rebels to retreat. Han and Leia escape with C-3PO and Chewbacca on the Millennium Falcon, but the ship's hyperdrive malfunctions. They hide in an asteroid field, where Han and Leia grow closer amidst tension and briefly kiss. Vader summons bounty hunters to assist in finding the Falcon. Luke, meanwhile, escapes with R2-D2 in his X-wing fighter and crash-lands on the swamp planet of Dagobah. He meets a diminutive creature who reveals himself to be Yoda; after conferring with Obi-Wan's spirit, Yoda reluctantly accepts Luke as his student. 
Question: Who is told to go train under Yoda?

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?

Ex Output:
Dot.

Passage: Joseph Jackson, patriarch of the Jackson family of musicians, was known for managing the careers of all nine of his children; most notably, the successful career of The Jackson 5. After arranging a recording contract with A&M in 1982 for a then 16-year-old Janet, he oversaw the entire production of her debut album, Janet Jackson, and its follow-up, Dream Street (1984); the latter of which was written and produced by her brothers Marlon and Michael, and Jesse Johnson. Best known as a television actress, she was initially reluctant to begin a recording career. She said, "I was coming off of a TV show that I absolutely hated doing, Fame. I didn't want to do [the first record, Janet Jackson]. I wanted to go to college. But I did it for my father ..." and elaborated that she was often in conflict with her producers. Amidst her professional struggles, she rebelled against her family's wishes by marrying James DeBarge of the family recording group DeBarge in 1984. The Jacksons disapproved of the relationship, citing DeBarge's immaturity and substance abuse. Jackson left her husband in January 1985 and was granted an annulment later that year.Jackson subsequently fired her father as her manager and employed John McClain, then A&M Records' senior vice president of artists and repertoire and general manager. Commenting on the decision, she stated, "I just wanted to get out of the house, get out from under my father, which was one of the most difficult things that I had to do, telling him that I didn't want to work with him again." Joseph Jackson resented John McClain for what he saw as an underhanded attempt to steal his daughter's career out from under him, stating, "I've worked hard for my family. The problem comes, though, when others come in behind you and try to steal them away. The wheels have already been set for Janet Jackson. Anyone who jumps on now will be getting a free ride." McClain responded by saying "I'm not trying to pimp Janet Jackson or steal her away from her father." He subsequently introduced her to the songwriting/production duo of James "Jimmy Jam" Harris III and Terry Lewis, former Prince associates and ex-members of The Time. 
Question: What is the first name of the person who released Dream Street?

Ex Output:

Janet.
