The correct answer is B.
Using indirect dialogue allows Twain to compress and shorten the conversation. By using fewer words (instead of including the exact dialogue), Twain can keep the scene short and move on to a more interesting part of the story.
If the dialogue were written out exactly as it was spoken, it would take a lot longer to read, since many animals are speaking to the donkey in this scene.
The answer would be "to help you decipher symbols and scale."
Without the key, a lot of the symbols would be quite confusing and you wouldn't know if it was 5 miles or 500 miles. Everything else is implied throughout the map, but the key's purpose is definitely to help you decipher symbols and scale.

This effect can influence riots and revolutions to end the Hunger Games and to end the emotional effects.
