Answer: The organizational principle that Janine demonstrated in her speech is the Recency Effect.
Explanation:
This type of organizational principle is when the order of the speech helps to form a judgment. When someone uses the recency effect, they are using the last of the speech to deliver the most memorable part, so that it is more likely to be remembered. This will leave a lasting impression on the people in the audience. The most recent and new information in the speech should be given last, instead of at the beginning. Many times during a speech, especially if it is to long, the audience will forget. Using this principle, they will remember the most important news.
