Answer:
Lighthouse 1 during the day will be warmer, lighthouse 2 during the night will be warmer.
Step-by-step explanation:
As the paragraph stated land absorbs heat and heats up faster than water. So during the day the lighthouse farthest away from the water will be hotter. But then the converse is true also land losses heat faster than water at night. So the water retains the heat from the day better making the lighthouse by the water warmer at night.
