Read the letter to the editor and then answer the question.

As a parent, I’m concerned that students are buying fizzy drinks in the school cafeteria every day, which affects their ability to learn. Too much sugar and caffeine makes it challenging for our students to concentrate. In addition, fizzy drink consumption can contribute to long-term health problems such as obesity and diabetes. I am not suggesting that Vairengte’s schools should dictate what students eat and drink, but I do believe our schools should promote and foster healthy lifestyles, including proper nutrition. Students should be allowed to bring their own fizzy drinks from home, but offering fizzy drinks in our cafeterias is unacceptable.
