The Lewis structure of PF3 shows that the central phosphorus atom has __________ nonbonding and __________ bonding electron pairs.
Is the answer 1, 3
Is it 1 because it asked for PAIRS- so there are two electrons not bonded- so one pair?

Yes, I think so. The person making the question could have made it clearer by writing "phosphorus atom has ???? non-bonding electron pairs and ?????bonding electron pairs."
