Engine noise from boats travelling through killer whales’ habitats ranges in frequency from 100 hertz to 3,000 hertz, an acoustical range that overlaps that in which the whales communicate through screams and squeals. Though killer whales do not seem to behave differently around running boat engines, engine noise from boats can be loud enough to damage their hearing over time. Therefore, _______.

Summary
Engine noise from boats traveling through killer whales’ habitats ranges from a frequency that overlaps with the acoustical range in which the whales communicate with each other. Although the whales do not act differently when the engine noise is present, the noise can be loud enough to cause hearing damage over time. Therefore… (the correct answer will be the conclusion).

Strongly Supported Conclusions
The engine noise could impact how killer whales communicate with each other after enough time.

A
younger killer whales are better able to tolerate engine noise from boats than older whales are
This is not supported by the stimulus and requires some unreasonable assumptions to make it work. You must assume that younger killer whales have been exposed to engine noise for a shorter period of time than older ones.
B
killer whales are less likely to attempt to communicate with one another when boat engines are operating nearby
The stimulus does say anything about what killer whales prefer.
C
noise from boat engines may impair killer whales’ ability to communicate
The stimulus says that engine noise *can* damage hearing loss over time. Killer whales communicate through screams and squeals. So, it is easy to support that boat engines could eventually impair the whales’ ability to communicate.
D
killer whales are most likely to prefer areas where boat traffic is present, but light
There is no support anywhere in the stimulus about what killer whales “prefer.”
E
killer whales would probably be more successful in finding food if boats did not travel through their habitats
You have to assume that killer whales communicate to find food. There is no evidence in the stimulus that supports this assumption.
