Costs: Spoiled food, damaged food, suitable storage. Benefits: Better athletics, better academics, less diabetes, lower obesity.
Explanation:
A cost refers to something that is paid, invested, or gave up when an alternative is chosen. On the other hand, a benefit refers to a positive effect related to a decision or election. In this context, elements such as spoiled food, damaged food, and suitable storage are costs of including healthy food in the school lunch, considering this is the "price" for including healthy food as this needs to be stored correctly and the risk it spoils or damages is higher.
On the other hand, elements such as better athletics or academics as well as less diabetes and obesity are benefits or positive effects because these factors increase the health of students; this is explained in "schools with healthy lunch programs have lower rates of childhood obesity and diabetes.... better in academics and sports".
