what is one possible advantage of hearing the characters voices as opposed to silently reading the scene?
hearing allows listeners to interpret the body language of each of the characters.
hearing allows listeners to understand the thoughts of each of the characters.
hearing allows listeners to associate a voice with each of the characters.
hearing allows listeners to focus on the actions of each of the characters.

Explanation:

When hearing characters' voices, listeners can assign a unique vocal - identity to each character, which is not possible in silent reading. Body language is not directly related to hearing voices only. Thoughts are usually not conveyed just by voices. Actions are also not the main advantage of hearing voices over silent reading.

Answer:

Hearing allows listeners to associate a voice with each of the characters.
