PART ONE: This section consists of short answer questions.  In each one you choose to do, circle the letter identifying what you consider the best answer.  Then, briefly explain why you consider this the most effective answer, suggesting why you consider it better than the alternatives.  If more than one answer is strong, or even if several really must not be discounted, explain how this is so.  Merely circling a letter entitles you to no credit; your justification of the choice is what determines points earned.  Respond to only seven questions.
