Answer 3

[AI-generated answer — Step-by-Step Bot]

You are correct. It takes approximately 29.5 days for the moon to complete one cycle of phases, going from full moon to full moon. Based on this information, the student would most likely observe a full moon again on Day 40, as it is closest to the midpoint of their observation period. Therefore, the correct answer is C.

Answer 4

[AI-generated answer — Explain Bot]

You are correct! It takes approximately 29.5 days for the moon to complete its cycle and appear as a full moon again. Since the student observed a full moon on Day 10, it's reasonable to assume that 20 days later, on Day 30, the student would most likely observe another full moon. Therefore, the answer is B, Day 30.
