Show summary

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. ██████ ██████ ██████ ██ ███ ████ ██ ██████ ███████████ ██████ ███████ ████ ████████ ██████ █████ ████ █████ ███ ██ ████ ██████ ██ ██████ █████ ███████ ████ █████ ██████████ ████████

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.
