Sarah is writing a paper explaining why public schools should provide healthy lunches to students, and she has several potential research questions. Which is her best option?

The best research question should directly support Sarah’s argument that schools should provide healthy lunches. Asking how healthier food could benefit students focuses on the effects of healthy eating on the people the policy would serve. The other questions are less connected: they ask what foods are healthiest, what students prefer, or what the general public wants, rather than why healthy lunches benefit students.
