Which of the following is an incorrect description of the function of dialogue ?

it conveys information
it influences characters
it relates an experience
it describes an action

I would say that what is not a main function of dialogue is describing an action and the main function is sharing information, especially where there are two strongly opposed points of view such as in a labour dispute or say in the present dispute between the right and left wing sides in Venezuela, iin such a way that the two sides can seek at least one perhaps small area that they can agree on and then try to move forward from there. Also, in these situations the experiences of the two sides need to be presented openly and honestly so that a compromise can be reached. In the process of the above, the characters of the disputants can change from being confrontational to conciliatory.
