Final answer:
Traveling storytellers in the fifteenth century often recited stories in town squares, a central public venue for gatherings and entertainment.
Step-by-step explanation:
In the fifteenth century, traveling storytellers often recited parables and humorous stories in various public venues. One of the most common places for these performances was the town square, which served as a central gathering area where people from all walks of life could come together. Unlike churches, which were primarily for religious worship, or taverns and marketplaces, which had their own specific functions related to trade and socializing, the town square provided a neutral space that was ideal for storytelling and reaching a wide audience. Thus, the correct answer is a) Town squares.
