According to Study 2, the temperature difference between the forest and dune sites at 9 p.m. on a typical summer day is approximately:
A. 0^◦C.
B. 5^◦C.
C. 8^◦C.
D. 15^◦C.

Study 2
Air temperatures were recorded hourly over a 24-hour period at 3 sites: above the deepest part of a large body of water (the lake site), an adjacent sand dune site, and a nearby forest site. Temperatures were recorded on 30 consecutive days during the summer and 30 consecutive days during the winter. Each hourly temperature was averaged for the season. The results are shown in Figure 2.
