[Q]: Passage: Bernard Chanticleer, called "Big Boy" by his parents, is 19 but still lives with his overbearing, clinging mother and his commanding, disapproving father, who is Curator of Incunabula at the New York Public Library. Bernard also works as a low-level assistant at the library, where his father is constantly monitoring and admonishing him. His father decides it's time he grew up and moved out of the family home in Great Neck and into his own Manhattan apartment. His mother is not happy about letting him go, but acquiesces to her husband and arranges for Bernard to live in a rooming house run by nosy, prudish Miss Nora Thing. Miss Thing inherited the building on the condition that her late brother's aggressive pet rooster be allowed to occupy the fifth floor, which Bernard must pass to get to his room. Miss Thing reassures Bernard's mother that the rooster only attacks girls, especially young pretty girls, to which Bernard's mother responds that her son isn't interested in girls yet, but arranges that Miss Thing will spy on Bernard and report any "female" activity. Bernard's mother also constantly mails locks of her hair to Bernard at his new residence.
Question: Who is said to not like girls?
[A]: Bernard Chanticleer.

[Q]: 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 (191213) 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?
[A]: Jackson.

[Q]: Passage: Percy Aldridge Grainger (born George Percy Grainger; 8 July 1882 20 February 1961) was an Australian-born composer, arranger and pianist who lived in the United States from 1914 on and became a citizen in 1918. In the course of a long and innovative career, he played a prominent role in the revival of interest in British folk music in the early years of the 20th century. Although much of his work was experimental and unusual, the piece with which he is most generally associated is his piano arrangement of the folk-dance tune "Country Gardens".
Grainger left Australia at the age of 13 to attend the Hoch Conservatory in Frankfurt. Between 1901 and 1914 he was based in London, where he established himself first as a society pianist and later as a concert performer, composer and collector of original folk melodies. As his reputation grew he met many of the significant figures in European music, forming important friendships with Frederick Delius and Edvard Grieg. He became a champion of Nordic music and culture, his enthusiasm for which he often expressed in private letters, sometimes in crudely racial or anti-Semitic terms.
In 1914, Grainger moved to the United States, where he lived for the rest of his life, though he travelled widely in Europe and in Australia. He served briefly as a bandsman in the United States Army during the First World War through 191718, and took American citizenship in 1918. After his mother's suicide in 1922, he became increasingly involved in educational work. He also experimented with music machines, which he hoped would supersede human interpretation. In the 1930s he set up the Grainger Museum in Melbourne, his birthplace, as a monument to his life and works, and as a future research archive. As he grew older, he continued to give concerts and to revise and rearrange his own compositions, while writing little new music. After the Second World War, ill health reduced his levels of activity. He considered his career a failure. He gave his last concert in 1960, less than a year before his death.
Question: What is the last name of the person who became a champion of Nordic music and culture?
[A]:
Grainger.
