Which of these is LEAST associated with the 1920s?
A: flappers
B: football
C: jazz
D: speakeasies
Of course jazz was VERY popular in the 1920s as it was at its big moments.
Speakeasies were originated from (1920-1933) so we have definite proof that those were of that time.
Flappers were a generation of young ladies in the 1920s from the West that usually wore short skirts, listened to jazz, etc.
So we have proof that the only plausible answer here is
B : Football
