Which of following is true about the urban people of Western Canada during the early years of the century?

During the early years of this century, wheat was seen as the very lifeblood of Western Canada. When crops were good, the economy was good; when the crops failed, there was depression. People on city streets watched the yields and the price of wheat with almost as much feeling as if they were growers. The marketing of wheat became an increasingly favorite topic of conversation.
     War set the stage for the most dramatic events in marketing the western crop. For years, farmers mistrusted speculative grain selling as carried on through the Winnipeg Grain Ex change. Wheat prices were generally low in the autumn, but farmers could not wait for markets to improve. It had happened too often that they sold their wheat soon after harvest when farm debts were coming due, only to see prices rising and speculators getting rich. On various occasions, producer groups asked for firmer controls, but governments had no wish to become in volved, at least not until wartime wheat prices threatened to run wild.
     Anxious to check inflation and rising living costs, the federal government appointed a board of grain supervisors to handle deliveries from the crops of 1917 and 1918. Grain Ex change trading was suspended, and farmers sold at prices fixed by the board. To handle the crop of 1919, the government appointed the first Canada Wheat Board, with full authority to buy, sell, and set prices.
