Answer: "The seagulls caught the food we threw to them."
Explanation: Since an active voice tells us what someone does, the sentence, "The seagulls caught the food we threw to them." uses an active voice.
Because a passive voice tells us what is done to something, the sentences "Sand had been blown all over the wooden deck of the restaurant.", "We were overcome by the smell of fresh ocean air and the sight of the glistening sand.", and "All of the shrimp had been eaten." use a passive voice.
Active voice presents the subject and action almost immediately, so the second sentence is written in active voice.
