Which statement best explains the relationship between new forms of entertainment in the 1920s and the fads of the era?

Radio broadcasts and films reached large audiences, so people could quickly learn about popular dances, fashions, and other fads. This makes “The availability of radio and film helped spread the word about new fads” the best explanation. The other choices either claim entertainment itself was only a fad or describe an unrelated end to 1920s rebellion.
