A student needs one sentence to introduce a counterclaim before a rebuttal. The topic is whether agriculture field trips should be added to environmental science courses. The writer favors the view that farm visits would help students see food systems and sustainability concepts in practice, while the opposing side reasons that field trips require transportation, permission forms, and backup plans that can be difficult to coordinate. Which sentence should the student use? Select the sentence that is accurate, fair, and not yet a rebuttal.
