Final answer:
While both tall tales and myths often include exaggeration, a larger than life hero, and seemingly impossible tasks, the element they do not universally share is a humorous tone. Myths may have humor but are primarily intended to convey cultural values and explanations of the world, unlike tall tales which are more focused on amusement.
Step-by-step explanation:
Tall tales and myths share many elements, such as exaggeration, a larger than life central hero, and seemingly impossible tasks. However, not all myths carry a humorous tone, which is typically found in tall tales. Myths are often seen as sacred stories that encode important beliefs, values, and morals of a culture. They may have elements of humor, but their primary intent is not always to amuse. Rather, myths serve to explain the world, promote religion, or imbue society with values. Therefore, the element that tall tales and myths do not universally share is a humorous tone.
The purpose of myths is multifaceted; they can aim to guide, instruct, or entertain. Creation myths serve as an excellent example, often explaining the origins of the world and the elements within it in a tone that is serious rather than humorous. The imagery and narrative within myths are built on the foundation of cultural significance and societal impact.
