Identify the audience and environmental variables that influence speech delivery

Your professor has asked you to give a speech at an upcoming job fair that will convince the audience to take the speech class in which you are currently enrolled. The job fair will be held in a part of the city with a relatively low unemployment rate and the people attending are likely to come from middle- to upper middle-class families. Many of them also work full-time and are looking for opportunities to advance their careers with higher education, but do not want to waste time or money on classes that won’t directly relate to their current work or their goals. You can’t gather all the characteristics of all the career fair attendees in advance, but you do know that the way in which you explain the advantages of taking this course and the type of language you use will affect the attendees’ decision on whether or not to enroll.
