"Is it a shark or a dolphin?"
Translation:Este un rechin sau un delfin?
No you can't. If you want to add the personal pronoun, you have to add it before the verb. It would be like "El este un rechin sau un delfin ?" It's exactly like if it wasn't a question, because in romanian, to make a question, you just have to add a question mark at the end of the sentence. Yeah, that's simple !
