Final answer:
The Groundhog Day tradition is entertaining because it includes fun events such as a scavenger hunt, talent show, and ball, and revolves around the whimsical legend of a weather-predicting groundhog.
Step-by-step explanation:
The evidence from the passage that supports the inference that Groundhog Day is an entertaining tradition is 'Over the years, these events have come to include a scavenger hunt, a talent show, and a ball'. These activities suggest that the day is about more than just predicting the weather; it's a day filled with fun and community engagement, indicative of a celebratory tradition. The legend of the forecasting groundhog itself adds to the entertainment value, as does the special pride the town of Punxsutawney takes in their groundhog, Punxsutawney Phil.
