Response is the goal, the basic intent, and the
final purpose of persuasion.
Advertising, for example, is meant to sell a product. Some ads may
be clever, witty, entertaining or educational, but if they don't
sell the product, they are not effective.
Certainly any "image building" ad, or
any "soft sell," or even any pleasant, inoffensive ad
could be defended or justified (by its creators) as achieving some
kind of vague goal. But, most commercial advertising is designed
to sell specific products, during a specific time, at a specific
cost-effectiveness.
If this isn't achieved, agencies lose their customers.
People lose their jobs.
Ads usually seek a simple response such as "buy,"
or the simple first step of a buying sequence: "Send for..."
or "See your dealer..." or "Call (800)...."
Making the response easy
is one of the persuader's most important jobs. It's not very useful
to call for a difficult, complex, or impossible response.
Removing obstacles to a response also includes
removing any fears or mistrust; thus, the importance of building
confidence in the speakers and the products.
Persuaders seek to make response easy, to limit
our options, and to use triggering words, or simple directives telling
us what to do.
Common response verbs include:
act
ask your doctor
buy
apply
call (toll free)
choose
click
come to
drink

Exposition usually does not seek an immediate
specific response.
In exposition, the goal is information-transfer and this information
is usually a means, later, to another end.
However, in addition to such specific utilitarian purposes,
much expository writing transfers information which may have no
specific identifiable purpose other than the reader's general
understanding of the subject.
Yet, such general understanding is a vital part of any civilization,
and of the "liberal education" of an individual.
People need to accumulate and pass on a great
deal of information, and a great variety of histories, analyses,
and interpretations of events in order to get a broader understanding
of a complex world.
The response that exposition usually seeks is
that of assent, belief, and acceptance.
Thus, the ideals of accuracy, credibility, and reasonableness
can be helped by the clarity and coherence of composition.
Persuasion is audience-centered,
usually seeks a specific response, and is judged on its effectiveness.
Exposition is topic-centered,
often seeks a more general assent, and is
usually judged on its intrinsic merits.
