Answer:
Since you need to form a question, but place the subject at the end, it means that the entire question will be really inverted, meaning that the order of words will be a little jumbled. This is the way to do it:
Termina a las dos la clase?
As you can see, the subject 'la clase' is placed at the end, and the word order is inverted.
Las calles cruzan en el CRUCE de calles.
