Answer:
An email to Sam's grandparents describing the winning run he made to win his Little League championship game this afternoon would most likely try to get the reader to have an emotional response to the story.
Step-by-step explanation:
Sam is writing an email to his grandparents about his important achievement - he won the Little League championship game. When we do something as great as winning a championship, we are overcome with emotion and want to share that with other people. This is why Sam's email will be full of emotion and try to get the reader to have an emotional response to the story as well.
