Explanation:

Looking at the "Average Perch Height in Trees" row, when there were no Brown Anoles, the average perch height was 70 cm. When Brown Anoles were present, the average perch height was 120 cm. This shows that after the Brown Anoles invaded (since one column is without Brown Anoles and one is with), over time, the green anoles' average perch height increased.

Answer:

C. After the brown anoles invaded, over time, the green anoles' average perch height increased.
