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?
answer:
Dot.

Passage: Sherman 'Tank' Turner is a help line operator and a ladies man with a hobby: If a guy loses a girl and wants her back, he gets in touch with Tank and pays him to take the girl on a bad date.  Throughout the evening Tank inevitably behaves in the most moronic fashion causing the girl to realize that her ex was not really such a bad guy after all and get back to their ex.
He shares an apartment with his step cousin Dustin who has fallen for his colleague Alexis. Dustin takes Alexis on a date and confesses his love but she insists they remain friends. After the date Dustin explains his situation to Tank who volunteers his services as a good friend (instead of having to pay for his services as usual). Dustin initially turns him down, not wanting Tank to be close to Alexis, but the next day sees Alexis flirting with another co-worker and begs Tank to take Alexis out. He accepts.
Tank bumps into Alexis and they arrange to go out.  He behaves badly all night but Alexis is too drunk to care. When he drops her off she expects him to come in but he resists the temptation out of loyalty to Dustin. Alexis calls Dustin but when they meet she explains that her date with Tank has motivated her to see other men.  Dustin sends Alexis roses and an apology poem in Tank's name.

Tank goes to see Alexis and they end up having casual sex on a regular basis while Dustin begins a series of desperate attempts to stay friends with her after all. 
Question: What is the alias of the person who volunteers his services to his cousin?

Passage: In Billings, Montana, a police officer arrives and discovers Woody Grant walking on the shoulder of the roadway. Woody is picked up by his son David, who learns that Woody wants to go to Lincoln, Nebraska, to collect a million dollar sweepstakes prize he believes he has won. When David sees the sweepstakes letter, he knows immediately that it is a mail scam designed to get gullible people to purchase magazine subscriptions. David brings his father home, where his mother Kate becomes increasingly annoyed by Woody's insistence on collecting the money.
After Woody is picked up again trying to get to Nebraska, David and his brother Ross discuss putting Woody in a retirement home. David pays a visit with his ex-girlfriend, Noel, who returns his belongings and refuses to move back in with him. Their conversation is cut short by a call from Kate reporting that Woody has taken off once again. David retrieves Woody and decides to drive him all the way to Lincoln, much to Kate's dismay.
While in Rapid City, South Dakota, Woody goes on a bender and hits his head while stumbling back to their motel room. David takes him to the hospital to get his head stitched up. David learns that they will be passing through Woody's hometown of Hawthorne, Nebraska, and suggests they spend the night with Woody's family. Woody is against the idea, but they end up going anyway.
They stay with Woody's brother Ray, his wife, and their two sons, Cole and Bart. Woody and David visit a mechanic shop Woody once co-owned, followed by some beers at a bar. When David brings up Woody's alcoholism and problems within the family—with Woody implying that he did not love Kate nor really want children—they get into an argument. At another bar, they meet Ed Pegram, whom the family blames for stealing Woody's air compressor decades ago. Over David's objections, Woody mentions winning the money and the barflies toast his good fortune. The next day, they learn that the news has spread through the town like wildfire. 
Question: What is Woody Grant's brothers name?

Ray.
