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,_______.
Which one of the following most logically completes theargument?
(A) younger killer whales are better able totolerate engine noise from boats than older whales are - WRONG. No differentiation as such is ascertainable from thepassage.
(B) killer whales are less likely to attempt tocommunicate with one another when boat engines are operatingnearby - WRONG. "less likely" may be because of its inability or may be behaviour because of boat enginenoise.
(C) noise from boat engines may impair killer whales’ ability tocommunicate - CORRECT. Correct sequence of flow as per passage.
