Final answer:
The researcher gives two reasons for tracking the lion recovery: to document the response of the lions to restoration efforts and to identify factors limiting their recovery.
Step-by-step explanation:
In the film, the researcher gives two reasons for tracking the lion recovery. First, it is important to track the lions to document the response of the lions to restoration of the park. This helps to understand how the lion population is recovering and whether the restoration efforts are successful. Second, tracking the lions allows researchers to identify factors limiting recovery of the lions. By studying their behavior and habitat, researchers can determine what factors are affecting the recovery of the lion population.
