Final answer:
Each December, people globally engage in holiday celebrations associated with the winter solstice, such as Christmas. Ancient structures like Stonehenge were used to mark this significant time. The season also inversely affects day and night cycles near the South Pole. The correct option is d. Everyone celebrates Christmas.
Step-by-step explanation:
Each December, many cultures around the world participate in various holiday celebrations. One pivotal event is the winter solstice, occurring around December 21, which is the shortest day of the year in the Northern Hemisphere. This time was traditionally used for family gatherings, sharing food and drink, and rituals to encourage the return of the sun and warmer weather.
Ancient structures like Stonehenge in England were likely built to track this significant seasonal change. Today, we continue to commemorate this time with holidays such as Christmas, which has both religious significance for Christians and secular aspects of celebration, like the story of Santa Claus. Additionally, in the Southern Hemisphere, and notably near the South Pole, the days and nights are significantly different during this period, with prolonged daylight, which would impact those on research expeditions at that time.
