Step-by-step explanation:
Ancient people interpreted the summer and winter solstices as important celestial events with significant cultural and agricultural implications. The summer solstice, which occurs around June 21 in the northern hemisphere, signified the longest day of the year and was celebrated as a time of abundance and gratitude for the warm weather. It helped agrarian societies determine when to sow their crops and anticipate seasonal rain. On the other hand, the winter solstice, around December 21, marked the shortest day of the year and was observed as a time to endure the lack of sunlight and cold temperatures. It was often associated with rituals to seek the return of light and heat.
