Final answer:
Pete will use the approach of envisioning an audience by using personal, firsthand knowledge or empathy to gain insight.
Step-by-step explanation:
When Pete is creating a picture of his audience for his message to parents, he will likely use the approach of envisioning an audience by using personal, firsthand knowledge or empathy to gain insight.
By drawing on his own experience as a superintendent, and as a parent and concerned resident, Pete can put himself in the shoes of the parents he is calling. This allows him to better understand their thoughts, feelings, and concerns, and tailor his message accordingly. For example, Pete can imagine how he would feel as a parent if his child achieved the prestigious title of valedictorian. He can envision the sense of pride, joy, and accomplishment that the parents would feel, and use this understanding to frame his greeting in a way that conveys his genuine appreciation and congratulations.
