Which of the following could you have seen if you had lived in the United States in the 1920s? soldiers marching off to the trenches in the Great War

engineers boarding ships to go build the Panama Canal

flappers listening to jazz and doing the Charleston

people standing in long lines at telegraph offices

I’d go with C. Jazz and the dance “The Charleston” were big and new in the 1920s.

Not A, because The Great War, World War I, ended in 1918.

Not B, because the Panama Canal was built from 1904 to 1914.

Regarding D: Telegraphs were sent from the 1840s-1977. If the question is supposed to have more than one answer, this would be a good second answer. But if the question has only one answer, go with C.
