to monitor their eating habits to monitor their roaming habits to monitor their sleeping habits to monitor their reproductive habits
I gave my students this multiple choice question: Many endangered animals are captured, tagged, and then released back into their environment. The tag may be a piece of coded plastic or metal that is placed somewhere safe on the body. Which is the most likely reason to tag an animal?

Only one answer is correct among these 4 choices:
- to monitor their eating habits
- to monitor their roaming habits
- to monitor their sleeping habits
- to monitor their reproductive habits

Could you tell me which one is correct?
