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. Alexis calls Tank at work and berates him for leaving early the previous night.  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?

Ex Output:
Tank.

Passage: Bartlett decided to send a team back to establish the exact location of the island that the Anderson party had approached, and to determine if Anderson had actually landed there. An injury to his knee ruled Mamen out from this mission, which was undertaken by ship's steward Ernest Chafe, with the Inuit pair, Kataktovik and Kuraluk. Chafe's group came within 2 miles (3 km) of Herald Island before being stopped by open water. A careful examination through binoculars revealed no signs of the missing party, and Chafe concluded that Anderson and company had not reached the island. Chafe and his party then returned to Shipwreck Camp.Meanwhile, on 4 February, Mackay and his group (Murray and Beuchat, joined by seaman Stanley Morris) announced they were leaving the next day, to seek land. Mackay presented Bartlett with a letter dated 1 February that began: "We, the undersigned, in consideration of the present critical situation, desire to make an attempt to reach the land." The letter requested appropriate supplies, and concluded by emphasising that the journey was on their own initiative and absolving Bartlett from all responsibilities. Bartlett allocated them a sledge, a tent, six gallons of oil, a rifle and ammunition and food for 50 days. They left on 5 February; the last sighting of them was a few days later, by Chafe and the Inuit, returning from their abortive trip to Herald Island. They found Mackay's party struggling to make headway, with some of their provisions lost and clothing and other equipment discarded to lighten their load. Beuchat in particular was in a distressed state, nearly delirious and in the throes of hypothermia. However, the party refused assistance and rejected Chafe's pleas that they return with him to Shipwreck Camp. Thereafter the only hint of their fate was a sailor's scarf belonging to Morris, later found buried in an ice floe. It was assumed that the four had either been crushed by the ice, or had fallen through it. 
Question: What were the last names of the people in Mackay's group?

Ex Output:
Murray.

Passage: The movie begins with a scooter chase between Harry and his nan because she didn't know it was him. Afterwards, Harry is sent to get a chicken for lunch, but they fire a machine gun at him and throw a grenade, which Harry throws into the chicken shed, blowing them up. Nan tells Harry the story of his twin brother, Otto, which Harry claims to have heard before. 
Suddenly, Harry and Nan then discover that their beloved pet hamster Abu is ill after he vomits a green substance on them, so they take him to the vet. He is almost put down until Harry takes him back home. Ed the vet and his assistant, Kisko, are working for Harry's neo-Nazi twin brother Otto who was abandoned by Nan in the 1970s, claiming it was because she couldn't look after them both, and was raised by Alsatians.
After another failed attempt to capture Abu (by disguising as a priest and a nun), Harry and Nan decide to take him on a trip in their Rover P6 to Blackpool for a week before he dies (when Abu really wanted to visit the home of Rihanna). Ed and his assistant pursue them on the road, until they arrive in "Blackpole" by mistake. The next day, Harry and Nan take Abu on a personal guided tour around the nuclear power plant by the cleaner.

While walking on the beach they encounter Barney Cull, a member of the Shell People.
