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?

Ex Output:
Jackson.

Passage: It is the Florida Everglades in 1863. Four deserters of the Confederate Army—Sergeant Todd, Plunkett, Cockney and the Kid—are hiding out. The Colonel, a fellow deserter, appears from the brush with a note from an Indian who has arranged to take him to the ocean so he may be taken to Cuba. When the Indian guide is found dead by Seminoles, the foursome reluctantly join forces with the Colonel in order to reach the coast and ride out the rest of the Civil War.
As the group treks through the dangerous Florida everglades, it's revealed that Plunkett has stolen a large amount of gold from the Confederate army, which Cockney wants to steal from him. The group continues its trek, and it is revealed Cockney is drop-dead afraid of snakes, and being in close contact with them sends him into a paralyzed state. Cockney also reveals that the Colonel deserted after giving drunk orders during the Battle of Murfreesboro, leading to a slaughter. A drought ensues, and when the group reaches water, they also find two dead fellow deserters, killed by Seminoles. The Colonel wishes to bury them, but the foursome disagrees, citing the danger of nearby Seminoles. However, the Kid changes their minds. Soon after, the Colonel begins experiencing troubles, getting a fever, and hallucinating. The group sees smoke, and the Sergeant (the leader of the group) goes to investigate and is attacked by a panther. The rest of the group follows and encounters a seemingly abandoned Seminole settlement. The Colonel, in his deranged state, charges head first into the encampment and is shot by an arrow. The Sergeant rejoins the group and they are attacked by Seminoles. Though they escape, the Colonel dies that evening. After the Colonel's death, the Sergeant declares that it's every man for himself. 
Question: What are the names of the people the Sergeant declares it's every many for himself to?

Ex Output:
Plunkett.

Passage: The year 1960 marked another turning point in Shostakovich's life: he joined the Communist Party. The government wanted to appoint him General Secretary of the Composers' Union, but in order to hold that position he was required to attain Party membership. It was understood that Nikita Khrushchev, the First Secretary of the Communist Party from 1953 to 1964, was looking for support from the leading ranks of the intelligentsia in an effort to create a better relationship with the Soviet Union's artists. This event has been interpreted variously as a show of commitment, a mark of cowardice, the result of political pressure, or his free decision. On the one hand, the apparat was undoubtedly less repressive than it had been before Stalin's death. On the other, his son recalled that the event reduced Shostakovich to tears, and he later told his wife Irina that he had been blackmailed. Lev Lebedinsky has said that the composer was suicidal. From 1962, he served as a delegate in the Supreme Soviet of the USSR. Once he joined the Party, several articles he did not write denouncing individualism in music were published in Pravda under his name. In joining the party, Shostakovich was also committing himself to finally writing the homage to Lenin that he had promised before. His Twelfth Symphony, which portrays the Bolshevik Revolution and was completed in 1961, was dedicated to Vladimir Lenin and called "The Year 1917." Around this time, his health began to deteriorate.
Shostakovich's musical response to these personal crises was the Eighth String Quartet, composed in only three days. He subtitled the piece "To the victims of fascism and war", ostensibly in memory of the Dresden fire bombing that took place in 1945. Yet, like the Tenth Symphony, this quartet incorporates quotations from several of his past works and his musical monogram. Shostakovich confessed to his friend Isaak Glikman, "I started thinking that if some day I die, nobody is likely to write a work in memory of me, so I had better write one myself." Several of Shostakovich's colleagues, including Natalya Vovsi-Mikhoels and the cellist Valentin Berlinsky, were also aware of the Eighth Quartet's biographical intent. Peter J. Rabinowitz has also pointed to covert references to Richard Strauss's Metamorphosen in the Eighth Quartet.In 1962 Shostakovich got married for the third time, to Irina Supinskaya. In a letter to Glikman, he wrote "her only defect is that she is 27 years old. In all other respects she is splendid: clever, cheerful, straightforward and very likeable." According to Galina Vishnevskaya, who knew the Shostakoviches well, this marriage was a very happy one: "It was with her that Dmitri Dmitriyevich finally came to know domestic peace... Surely, she prolonged his life by several years." In November he made his only venture into conducting, conducting a couple of his own works in Gorky; otherwise he declined to conduct, citing nerves and ill health. 
Question: What is the first name of the person who was required to attain Party membership in order to hold the position of General Secretary of the Composers' Union?

Ex Output:

Dmitri.
