To find the answer to your first question about a new form of signage in Canada during the 1920s, we need to look for a word that is four letters long and has the letter "E" as the second letter. One possible answer could be "neon." Neon signs were first introduced in the 1920s and gained popularity during that time. These signs used neon gas to produce vibrant colors and were commonly used for advertising and outdoor displays.

Regarding your second question about the leader in the Winnipeg General Strike, we are looking for a three-letter word with the last letter being "U." The leader of the Winnipeg General Strike in 1919 was Arthur "Ginger" Goodwin, who was a fervent labor activist and represented the striking workers.

Lastly, for Canada's involvement in an international group during the 1920s, we need to find a six-letter word with the last letter being "E." The answer is most likely "League," referring to the League of Nations. The League of Nations was an international organization established in 1920 as part of the Treaty of Versailles after World War I. Its goal was to maintain peace and promote international cooperation. Canada was a founding member of the League of Nations, highlighting its involvement in international affairs during the 1920s.
