answer the question in the same yhat you would answer "is it
that..." in English. "Est-ce que" is not a complete question but
calls for the object of the question. Est-ce que tu as garé la
voiture ? is "did you park the car?" Est-ce que la voiture est
garée ? is "is the car parked?" Est-ce que la voiture est bleue,
ou est-ce qu'elle est rouge ? is "Is the car blue, or is it
red?
