Step-by-step explanation:
In Spanish, you can form three types of questions.
To form a question with Intonation, you simply change the way you say it, raising your voice at the end; this translates to adding question marks when you need to write the question.
You can also form a question by adding a Question Tag at the end of an affirmation. Question tags examples can be: ¿verdad?; ¿no es cierto?.
Last but not least, to form a question you can use Inversion: to do this you simply have to switch the order of the subject and the verb.
