Task: Question Generation
Input (English): Passage: Thomson's most famous paintings are his depictions of pine trees, particularly The Jack Pine and The West Wind. David Silcox has described these paintings as "the visual equivalent of a national anthem, for they have come to represent the spirit of the whole country, notwithstanding the fact that vast tracts of Canada have no pine trees", and as "so majestic and memorable that nearly everyone knows them". Arthur Lismer described them similarly, saying that the tree in The West Wind was a symbol of the Canadian character, unyielding to the wind and emblematic of steadfastness and resolution.Thomson had a great enthusiasm for trees and worked to capture their forms, their surrounding locations, and the effect of the seasons on them. He normally depicted trees as amalgamated masses, giving "form structure and colour by dragging paint in bold strokes over an underlying tone". His favourite motif was of a slight hill next to a body of water. His enthusiasm is especially apparent in an anecdote from Ernest Freure, who invited Thomson to camp on an island on Georgian Bay:
One day while we were together on my island, I was talking to Tom about my plans for cleaning up the dead wood and trees and I said I was going to cut down all the trees but he said, "No, don't do that, they are beautiful."
The theme of the single tree is common in Art Nouveau, while the motif of the lone, heroic tree goes back even further to at least Caspar David Friedrich and early German Romanticism. Thomson may also have been influenced by the work of MacDonald while working at Grip Limited. MacDonald in turn was influenced by the landscape art of John Constable, whose work he likely saw while in England from 1903 to 1906. Constable's art influenced Thomson's as well, something apparent when Constable's Stoke-by-Nayland (c. 1810–11) is compared with Thomson's Poplars by a Lake.Thomson's earlier paintings were closer to literal renderings of the trees in front of him, and as he progressed the trees became more expressive as Thomson amplified their individual qualities. Byng Inlet, Georgian Bay shows the broken, high-keyed colour that Thomson and his colleagues experimented with later in his career, and is similar to Lismer's Sunglow. While Lismer only applied the technique to the water, Thomson applied it throughout the composition. According to MacCallum, Thomson worked on Pine Island, Georgian Bay over an extended period. He wrote that this painting had "more emotion and feeling than any other of [Thomson's] canvases". In contrast, MacDonald found it "rather commonplace in color & composition & not representative of Thomson at his best".
Output (English): What piece of art is used to compare to Thomson's Poplars by a Lake to prove that he was inspired by the landscape artist?
