Question: Passage: In October, MacDonald introduced Thomson to Dr. James MacCallum. A frequent visitor to the Ontario Society of Artists' (OSA) exhibitions, MacCallum was admitted to the Arts and Letters Club in January 1912. There, he met artists such as John William Beatty, Arthur Heming, MacDonald and Harris. MacCallum eventually persuaded Thomson to leave Rous and Mann and start a painting career. In October 1913, MacCallum introduced Thomson to A. Y. Jackson, later a founder of the Group of Seven. MacCallum recognized Thomson's and Jackson's talents and offered to cover their expenses for one year if they committed themselves to painting full time. MacCallum and Jackson both encouraged Thomson to "take up painting seriously, [but] he showed no enthusiasm. The chances of earning a livelihood by it did not appear to him promising. He was sensitive and independent, and feared he might become an object of patronage." MacCallum wrote that when he first saw Thomson's sketches, he recognized their "truthfulness, their feeling and their sympathy with the grim fascinating northland ... they made me feel that the North had gripped Thomson as it had gripped me since I was eleven when I first sailed and paddled through its silent places." He described Thomson's paintings as "dark, muddy in colour, tight and not wanting in technical defects". After Thomson's death, MacCallum helped preserve and advocate for his work.Thomson accepted MacCallum's offer under the same terms offered to Jackson. He travelled around Ontario with his colleagues, especially to the wilderness of Ontario, which was to become a major source of inspiration. Regarding Algonquin Park, he wrote in a letter to MacCallum: "The best I can do does not do the place much justice in the way of beauty." He ventured to rural areas near Toronto and tried to capture the surrounding nature. He may have worked as a fire ranger on the Mattagami reserve. Addison and Little suggest that he guided fishing tours, although Hill finds this unlikely since Thomson had only spent a few weeks in the Park the previous year. Thomson became as familiar with logging scenes as with nature in the Park and painted them both.While returning to Toronto in November 1912, Thomson stopped in Huntsville. The visit was possibly to meet with Winfred Trainor, a woman whose family owned a cottage on Canoe Lake in Algonquin Park. Trainor was later rumoured to have been engaged to Thomson with a wedding planned for the late 1917, although little is known about their relationship.Thomson first exhibited with the OSA in March 1913, selling his painting Northern Lake (1912–13) to the Ontario Government for $250 (equivalent to CAD$5,600 in 2018). The sale afforded him time to paint and sketch through the summer and fall of 1913. 
Question: What was the last name of the person who was a founder of the Group of Seven?

Answer: Jackson.


Question: 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.


Question: Passage: Following the release of The Final Cut, Waters embarked on a solo career. In 1984, he released his first solo album, The Pros and Cons of Hitch Hiking, a project about a man's dreams across one night that dealt with Waters' feelings about monogamy and family life versus "the call of the wild". In the end the character, Reg, chooses love and matrimony over promiscuity. The album featured guitarist Eric Clapton, jazz saxophonist David Sanborn, and artwork by Gerald Scarfe. Kurt Loder described The Pros And Cons of Hitch Hiking as a "strangely static, faintly hideous record". Rolling Stone rated the album a "rock bottom one star". Years later, Mike DeGagne of AllMusic praised the album for its "ingenious symbolism" and "brilliant use of stream of consciousness within a subconscious realm", rating it four out of five stars.Waters began touring in support of the album, aided by Clapton, a new band, new material, and a selection of Pink Floyd favourites. Waters débuted his tour in Stockholm on 16 June 1984. The tour suffered from poor ticket sales and some performances at larger venues were cancelled; Waters estimated that he lost £400,000 on the tour. In March 1985, Waters went to North America to play smaller venues with the Pros and Cons Plus Some Old Pink Floyd Stuff—North America Tour 1985. The Pros and Cons of Hitch Hiking has been certified Gold by the RIAA.In 1986, Waters contributed songs and a score to the soundtrack of the animated movie When the Wind Blows, based on the Raymond Briggs book of the same name. His backing band featuring Paul Carrack was credited as The Bleeding Heart Band. In 1987, Waters released Radio K.A.O.S., a concept album based on a mute man named Billy from an impoverished Welsh mining town who has the ability to physically tune into radio waves in his head. Billy first learns to communicate with a radio DJ, and eventually to control the world's computers. Angry at the state of the world in which he lives, he simulates a nuclear attack. Waters followed the release with a supporting tour also in 1987. 
Question: What is the last name of the person whose backing band was credited as The Bleeding Heart Band?

Answer:
Waters.
