Task: Question Answering
Input (English): Passage: With MacCallum's year of financial support over, Thomson's financial future became uncertain. He briefly looked into applying for a position as a park ranger, but balked after seeing that it could take months for the application to go through. Instead, he considered working in an engraving shop over the winter. He made little effort to sell his paintings, preferring to give them away, though he brought in some money from the paintings he sold. In mid-November, he donated In Algonquin Park to an exhibition organized to raise money for the Canadian Patriotic Fund. It was sold to Marion Long for $50 (equivalent to CAD$1,100 in 2018).In the spring of 1915, Thomson returned to Algonquin Park earlier than he had in any previous year and had already painted twenty-eight sketches by April 22. From April through July, he spent much of his time fishing, assisting groups on several different lakes, and sketching when he had time. In July, he was invited to send paintings to the Nova Scotia Provincial Exhibition in September. Because he was in Algonquin Park, his friends selected three works to send—two unidentified works from 1914 and the sketch Canadian Wildflowers. From the end of September to mid-October, he spent his time at Mowat, a village on the north end of Canoe Lake. By November, he was at Round Lake with Tom Wattie and Dr. Robert McComb. In late November, he returned to Toronto and moved into a shack behind the Studio Building that Harris and MacCallum fixed up for him, renting it for $1 a month.In 1915, MacCallum commissioned MacDonald, Lismer and Thomson to paint decorative panels for his cottage on Go-Home Bay. In October of that year, MacDonald went up to take dimensions. Thomson produced four panels which were probably meant to go over the windows. In April 1916, when MacDonald and Lismer went to install them, they found that MacDonald's measurements were incorrect and the panels did not fit. 
Question: What is the name of the person who made little effort in selling his paintings?
Output (English): Thomson.
