    Is the alarm that sounds when you open the door while the lights are on in your car an OR circuit or an AND circuit, and why?

    Which of the two statements is true?
    1) It comes on when either the lights are on OR the door is open.

    2) It comes on when both the lights are on AND the door is open.
