What are some well written sentences of an introduction, body, and closure for a college student's Oral Communications Persuasive Speech presentation on the vending machines throughout the buildings on her college campus?

In the introduction to this speech, the speaker must state her opinion clearly and powerfully. For example, she must state something along the lines of the following: "Vending machines must be placed throughout the campus to ensure that students have access to food and drink when the dining services are closed" (the speaker could also advocate for no vending machines on campus). The introduction must succinctly state the speaker's opinion and the overall reason for her opinion. In the body of the speech, she must clearly explain the reasons for her opinion in more detail, perhaps detailing the reasons that students must have access to vending machines and the hours when they cannot access other food or drink. It may be helpful for the student to enumerate her reasons; for example, she can state that there are three reasons that vending machines are necessary and explain each reason in depth. In the closure of her speech, she must summarize her opinion and provide a call to action. For example, she can tell the audience that they should contact the university president to advocate for more vending machines on campus.
