You will state what each person should do to get ready for a party you're throwing. You must use the verb "deber" along with an infinitive verb phrase. For example: Q: Luisa y Roberto: traer las mesas A: Luisa y Roberto deben traer las mesas. Notice I conjugated the verb "deber" but I left the verb phrase IN THE INFINITIVE! Think of "deber" like the verb "querer" or "poder": verbs that follow them must stay in the infinitive. Watch accents and spelling!
