The correct answer is A. The theme of tradition is developed through the use of details in the setting such as date, time of the day, and sensory images.
It is clearly stated that June 27 was an important day because it is when the ritual takes place. Jackson meticulously illustrates how people gather in the town centre that morning. The children arrive first because school was over for the summer; next the adults arrive preparing in a ritualistic manner for the event. Jackson continues to highlight the importance of the date and how this ritual has been preserved for generations.
