[EX Q]: Passage: Born without an immune system, Jimmy Livingston is forced to live in a sterilized dome in his bedroom, earning him the nickname "Bubble Boy" by his neighbors. Jimmy's overbearing and devout Christian mother only exposes him to Highlights magazine and the Land of the Lost for entertainment. When he is a teenager, a girl named Chloe moves in next door. Jimmy is immediately taken with her, and eventually befriends her despite his mother's discouragement.
Chloe visits Jimmy and tells him that she is leaving for Niagara Falls to marry her  boyfriend, Mark, in three days. Jimmy  realizes that Chloe cares for him. Realizing how much he cares for her, Jimmy builds a mobile bubble suit and runs away from home, determined to stop the wedding.
On the first day of his journey, he's unable to afford a bus ride to Niagara Falls, but is picked up by an overly enthusiastic cult on a pilgrimage towards enlightenment. By this time, Jimmy's mother has discovered her son missing, so she and her husband set off to find Jimmy.
While traveling through the desert, Jimmy meets Slim, a  biker with a flat tire. Jimmy offers to fix the flat with some patches and the two become friends. Elsewhere, Gil, the leader of the cult Jimmy met, has revealed that their messiah is "the round one," and that whoever rejects him will suffer. The group who abandoned Jimmy set off to find him. Jimmy and Slim have traveled to Las Vegas for traveling money. However, Slim gets caught up in the Vegas life so Jimmy goes on without him.

[EX Q]: 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 A]: Dot.

[EX Q]: Passage: Fields plays a hot-tempered dentist who terrorizes his patients, who verbally/physically abuses his assistants and golfing-caddies alike, and whose daughter desires to marry an ice-delivery man. Fields disapproves of this match, especially after the starry-eyed daughter attempts to elope with her lover. Fields locks his daughter in her upstairs bedroom which is located above his dental office, where she proceeds to stamp her feet, causing plaster chunks to fall as he attempts to treat his patients.  Various patients with unusual physical traits (a tall "horse"-faced woman, a tiny, heavily-bearded man [Fields is obliged to use a stethoscope to locate the man's mouth]) arrive at the office, and he attempts to use his dental drill on them without any apparent pain killer. With one of his patients (Elise Cavanna), he engages in an intimate wrestling match as he attempts to extract a painful tooth.
Eventually the ice-delivery man procures a tall ladder and aids the dentist's daughter to escape from her dormitory window.  Fields observes the lovers just as they are prepared to run off, and --- under pressure from the sizable crowd that has gathered at the foot of the ladder --- grudgingly withdraws his opposition to the match.  The film ends with Fields --- who had previously  threatened to purchase an electric refrigerator instead of ordering ice each day --- contemptuously ordering his now-future-son-in-law to deliver "fifty pounds of ice, and be quick about it", prompting the daughter to joyfully embrace her fiance. 
Question: What is the name of the person who tries to treat his patients while his daughter stomps on the floor?
[EX A]:
Fields.
