Question 1 (2 points)
Read the paragraph from the section "How Scientists Listen To Sounds Underwater."
The scientists then analyzed these recordings. They noted the loss of sound over distances and the levels of background noise.
They think that without background noise, rasps from large lobsters could be heard up to 3 kilometers (1.9 miles) away.
However, experts are still not sure if the lobsters' own hearing is good enough to detect these sounds across long distances.
