Forma correcta de escribir una pregunta de la que sospechas la respuesta?

Question

In a question where we suspect to know the answer, where do I have to put the closing question mark:

Answer 1

Could you explain more if this doesn't answer your question?

The question marks in Spanish are similar to those in English (with the exception of the beginning '¿' at the start of a question). So in that regard it would go at the end of the phrase.

Eg.

Son las tres. ¿Verdad?

or

¿Ya son las tres?
