Two scientists want to determine if dolphins vocally mimic the pitch of our voices in attempt to communicate. The scientists track each time a given dolphin's vocalization matches the pitch of their voices when the scientists are talking, but not directly communication with the dolphin. Then, they record the pitch of another dolphin's vocalization when the scientists are talking directly to the dolphin. Both times the scientists talked for 3 minutes. Identify each of the following parts of this experiment below by matching them together.
