Question: Assuming an absolutely dry environment in the center of the Sahara Desert with the same temperature and atmospheric pressure as in the image, if a tuning fork is struck at the sound source in both places at the same time, in which environment would a distant observer hear the sound first?
A. In the environment shown in the image
B. In the Sahara Desert environment
C. They would be heard at the same time in both environments
D. Cannot be determined, because sound speed is also affected by altitude
Clues:
1. A stream of water is flowing over rocks in the foreground and middle ground.
2. The scene is a dense forest with numerous trees with green leaves.
3. There is lush green vegetation and undergrowth on the banks of the stream and throughout the forest floor.
4. Beams of sunlight are visible passing through the tree canopy, indicating the presence of atmospheric particles like mist or water vapor that scatter the light.
5. Rocks in and near the stream appear wet and some are covered in what looks like green moss.
