第二题

What is the professor’s opinion of past assumption about turtle communication?

AThey were largely based on a flawed study.

BThey were insightful but applied to only a few turtle species.

CThey failed to address turtle communication on land as well as in water.

DThey delayed further research on turtle communication.

第三题

In the study the professor describes, at what point during nesting did researchers begin monitoring leatherback nests for sound?

AWhen the eggs were first laid

BWhen the embryos’ ears were developed enough to hear

CWhen the eggs first started to hatch

DWhen the hatchlings started to communicate with one another

第四题

What does the professor imply when she talks about the sounds emitted from leatherback turtle nests?

ACommunication appears to occur only at certain times of day

BThe complexity of sound is partly dependent on the nest’s distance from the ocean

CEmbryos may emit sounds in order to coordinate group behavior

DThe sounds emitted by embryos are less complex than those emitted by hatchlings

Select 2 answers

A AThey are more likely to avoid capture by predators

BThey have an increased chance of finding food

CThey conserve energy while leaving the nest.

第六题

Why does the professor mention noise pollution?

ATo question whether the results of a study were affected by external factors

BTo suggest a reason why turtle communication can be difficult to study
