I believe that the correct answer is D because it is already stated once that they need the sirens so it is giving us a fact that has already been stated.
Answer:
Passage 1 is first person.
Passage 2 is Third person.
Passage 3 is Third person.
Passage 4 is second person.
Explanation:
The first person sentence starts with my or I. This is situation in which a narrator wants to mention something about himself. Second person is you. The narrator directly communicates and refers to the other person. Third person is when narrator mentions he or she. In this situation narrator is talking about someone who is not direct object.
A school of anchovies or a gaggle of geese or even a pod of orca whales would be a population. A population refers to all members of the same species.
