Answer:
The response which shows that Desmond's supervisor is engaged in effective listening is:
d. I'll call the police right away and ask the to help with the bridge closure and diverting traffic.
Step-by-step explanation:
To show that he was listening effectively to what Desmond said, his supervisor must address the most important topics discussed by Desmond. His response must show that he understands the situation and takes it seriously. And that is why letters A, B, C, and E are inappropriate. Some of them show that he is not listening at all, while others show that he does not care. For instance, it is utterly inappropriate for the supervisor to prioritize his vacation over people's safety.
The best response is found in option D. Here, the supervisor clearly grasps the urgency of the situation. He understands people are in danger and does not postpone any actions. Quite the contrary, he states that he will contact the police so that they can close the bridge immediately.
