principle of speech

Within Ethos we use the terms Prior (Initial), Derived, & Terminal.
First, define each term in your own words, and then give me three elements or actions that might contribute to a positive "Derived Ethos."

Create a Disjunctive Enthymeme using the following sentence as a Minor Premise (remember - the minor premise is the middle sentence):

"Regular semester classes drag on too long."

Once you've completed the enthymeme, state and apply the appropriate tests.
