On February 2 of each year, the United States observes the unusual holiday Groundhog Day, a day of hope that winter is over and spring is beginning. The tradition has been officially observed in the US since the 1800s and is believed to have developed from European folk traditions in which a bear, fox, badger, or even hedgehog would serve as the symbolic metrologist. Although other cultures and towns observe Groundhog Day (or something similar) the town of Punxsutawney, Pennsylvania takes special pride in being home to the one true forecasting, the groundhog, Punxsutawney Grounding Club to perpetuate the joyful rituals and events surrounding Groundhog Day. Over the years, these rituals and events have come to include a scavenger hunt, a talent show, and a ball. Legend has it that on Groundhog Day the official weather-forecasting groundhog awakens from hibernation and comes out of his burrow to look for his shadow. If he sees his shadow, six more weeks of winter are to come and Punxsutawney Phil goes back to bed. However, if he does not see his shadow, Punxsutawney Phil takes this as a sign that spring has arrived and he remains above ground. Of course, common sense tells us that February 2 is too early for spring to begin and that while animals may be attuned to various elements of nature from which humans might learn, they are unlikely to act on their instincts based on a schedule set by the Gregorian calendar. Nevertheless, a visit to Pennsylvania to the Punxsutawney Phil and all the fun inspires each year might provide the loath of hope needed to reach the end of winter. What source would be most useful in determining reliability of Punxsutawney Phil’s predictions over a number of years?
A. A historical survey of customs in Pennsylvania
B. An encyclopedia entry on mammals in the northeast U.S
C. A record of weather patterns in the last decade
D. A memoir from a member of the Groundhog Club
Weather patterns in the last decade would determine the reliability of the predictions of the symbolic metrology of the Groundhog’s day.
Therefore, the Correct Answer is C.
