At first glance, the notion of communication being both presentational and representational is difficult to grasp. Explain the difference.

What will be an ideal response?

When people speak to others, they have a number of words—their entire
vocabulary, in fact—that can be used to construct their message. They will choose
some words and not choose other words; they will arrange the chosen words in a
certain way and not in other ways—both presentational acts. However, their selection of
words and the arrangement of those words are meaningful acts. Their use of words and
their construction of messages do not just represent ideas and information; these acts
present their view of the world to others—the representational side of communication.
