Final answer:
The thesis statement is that students should have lockers, while the topic sentences discuss theft prevention, cleanliness, and health benefits. The conclusion strategy is a call to action.
Step-by-step explanation:
The response to the student's question about the essay concerning lockers for students can be broken down into three parts: identifying the thesis statement, highlighting the topic sentences, and determining the strategy used in the conclusion. The thesis statement that should be highlighted green is: "That is why I think students should have lockers." The three topic sentences to highlight are: "Students should have lockers because it will stop people from stealing their stuff.", "Students also should have lockers so they will have a clean place to put their books.", and "My final reason why I think students should have lockers is so students won't complain about caring everything at once." Lastly, the strategy included in the conclusion is (a) a call for action, where the author urges the reader to contact the principal and demand lockers for the school.
