Question
A behavioral scientist wants to know whether a bird would chirp more if it had a mirror in its cage. He recorded how many chirps he heard 2 hours a day for one week. Then he added a mirror to the cage and recorded the chirps again.
What does he need to do for his experiment to work?
1. record the chirps in the morning on some days and the afternoon on other days
2. use the same method for recording chirps each week
3. keep the cage in the same location each day

For the experiment to work effectively, the behavioral scientist needs to ensure consistency in the conditions under which the chirps are recorded. This means using the same method for recording chirps each week (Option 2) and keeping the cage in the same location each day (Option 3) to minimize environmental variables that could influence the results.
Therefore, the best answer is:
**2 and 3 only**
