Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: By 1911, Winnipeg was Canada's third-largest city. However, the city faced financial difficulty when the Panama Canal opened in 1914. The canal reduced reliance on Canada's rail system for international trade; the increase in shipping traffic helped Vancouver to surpass Winnipeg in both prosperity and population by the end of World War I.
More than 30,000 workers walked off their jobs in May 1919 in what came to be known as the Winnipeg general strike. The strike was a product of postwar recession, labour conditions, the activity of union organizers and a large influx of returning World War I soldiers seeking work. After many arrests, deportations, and incidents of violence, the strike ended on 21 June 1919 when the Riot Act was read and a group of Royal Canadian Mounted Police officers charged a group of strikers. Two strikers were killed and at least thirty others were injured on the day that became known as Bloody Saturday; the event polarized the population. One of the leaders of the strike, J. S. Woodsworth, went on to found Canada's first major socialist party, the Co-operative Commonwealth Federation, which later became the New Democratic Party.The Manitoba Legislative Building, constructed mainly of Tyndall stone, opened in 1920; its dome supports a bronze statue finished in gold leaf, titled "Eternal Youth and the Spirit of Enterprise" (commonly known as the "Golden Boy"). The stock market crash of 1929 and the Great Depression resulted in widespread unemployment, worsened by drought and low agricultural prices. The Depression ended after the start of World War II in 1939.
What current political party did J.S. Woodsworth find?
