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?

elle a accroché des affiches des Avengers 

Non, Je n'ai faim pas j'ai soi

Is this the correct negativ form: Paul n'a-t-il pas regardé la télé ?

A quick question regarding this sentence, Je n'avais pas L'habitude de prendre le train." My answer was "I don't usually take the train." Like saying that I usually drive so I don't usually take the train." The correct answer was "I didn't usually take the train." That just sounds wrong to my ears. Could it be a typo and should have read "I didn't used to take the train." If not can you please explain the latter sentence. Perhaps with an example of two for context.
