What is the concentration of fluoridation in school water compared to community water?

1.5x
2.5x
3.5x
4.5x

The correct answer is: 4.5x

Community water typically has a concentration of 0.7-1.2 parts per million (ppm) of fluoridation, while schools are required to have a slightly higher concentration of 1.2-1.5 ppm. Therefore, the concentration of fluoridation in school water is roughly 4.5 times higher than in community water. This is to ensure that children, who spend a large portion of their day at school, are receiving enough fluoride to protect their teeth from cavities. The other options (A, B, and C) are incorrect because they are not proportionally higher than the range of fluoridation concentration in community water.
