O Dialogue develops characterization and mood.

Explanation:

Dialogue is a conversational exchange between at least two individuals and an artistic and showy structure that portrays such an exchange. Successful dialogue should do numerous things on the double, not just pass on data, but also informative message.  

The motivation behind why writers use discourse in their bits of writings is to assist the peruser with getting to know the character while likewise uncovering the character's feelings and activities.  In any case, the principle thought of utilizing discourse is to show reality, for example, a discussion between characters.  

Dialogue should do one of three things and they are:

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in the first case the pronoun it probably refers to the car but it has not been mentioned before so we should replace it for the car. in doing so the statement becomes clear.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
