"Croyez-vous que ce sont les mêmes ?"
Translation:Do you think they are the same?
The statement-as-question is common in spoken French; somewhat less so in English. But when the French uses a standard question format, e.g., inversion, be sure to put your translation in the form of a standard question in English. Remember that the statement-as-question form is only used in spoken language--not in writing.
