PrepTest 84, Section 2, Question 10
Various studies have concluded that song overlapping, the phenomenon where one bird begins a song while another of its species is singing, is a signal of aggression. These studies are based solely on receiver-response tests, which seek to derive conclusions about the intent of a signal based on how others respond to it. However, any response�even no response�can be interpreted as a reaction to perceived aggression. Therefore, _______.

Which one of the following most logically completes the argument?
birds do not respond in a predictable manner to signals of aggression
receiver-response tests can provide no insight into bird behavior
song overlapping is likely not a signal of aggression
song overlapping has no communicative function
the conclusion of these studies is unconvincing
