Which definition of lore best matches the most common definition given by the dictionary entry?

The answer is "a lesson".
The idea of learning/teaching comes up 2 times, while the face idea, the tale idea, and the superstition idea each only come up once.
Answer:
A Lesson
Explanation:
Lore can be a tale, but it is so much more than that. Another dictionary definition for lore is: "a body of traditions and knowledge on a subject or held by a particular group, typically passed from person to person by word of mouth."
Here, it is quite clear that it is knowledge, but it can be much more than a tale. So lesson most likely is the one that fits.
