Respuesta :
D is the answer because it offers no evidence and support to the claim that an open campus is a good idea.
The correct answer is D. The cafeteria serves students’ favorite meal, pasta with breadsticks, on Fridays.
Explanation:
An appropriate supporting detail should prove or explain how the main idea or point is true. This implies a supporting detail to "Springville High should have an open campus" should show the importance or advantages of an open campus or a campus that allows students to go out during lunchtime or similar. In this context, the detail that is least supportive is "The cafeteria serves students’ favorite meal, pasta with breadsticks, on Fridays" because this detail only explains the menu of the cafeteria but not the advantage or positive aspects of an open campus. Indeed, different from other details this detail is not related to the main topic, and therefore it does not support the main idea.
