Which sentence in the passage should be revised for wordiness?
Have you ever wondered what’s in your water? At first glance, you may think there is nothing—it’s just water! But for many people in cities and towns across America, the water is fluoridated. Fluoridation is the process in which fluoride is added to water supplies to help people fight tooth decay. Fluoride has a positive and healthy effect on teeth. It makes teeth stronger, tougher, harder, and much less likely to ever develop cavities or get excess plaque buildup.
Fluorides are compounds that contain the mineral fluorite. They are found in the earth. Almost all water naturally contains some level of fluoride, even if it is a small amount. However, some areas have water supplies that have naturally higher levels of fluoride. Scientists in the 1930s found that people who drank water with more fluoride had fewer cavities.
Today, more than half of the tap water used in the United States is fluoridated. The decision to fluoridate is left up to individual cities. When a community decides whether to fluoridate the water supply, the topic can become controversial. Some people claim there is a link between fluoride and health problems. But others argue there is not enough evidence to support this claim.
