In the exercise “La Super Chambre de ma Fille”, I filled the blank in the following sentence with the word “affiches” for “posters” but it marked my answer as Incorrect and said I should have used the word “posters”.   Doesn’t “affiches” also mean posters?

Hi

Please could you tell me how Reims should be pronounced

In this context, could you also use 'certains courent, les autres crient' ?

thank you

why? Rue is feminine. Or why not just à .  Or is this another one of those times when french just works that way and there's no logical reason?
