- Because energy is being transferred from the sun to the ground and then from the ground to the girl, but not because energy is being transferred directly from the sun to the girl
- Because energy is being transferred from the sun to the air and then from the air to the girl, but not because energy is being transferred directly from the sun to the girl
- Because the sun is shining on the girl, not because energy is being transferred from the sun to the girl
