read the text.\nfluoride is a mineral that is added to public drinking water supplies in much of the united states in order to reduce levels of tooth decay. when a tooth is forming, fluoride strengthens the enamel, or outside coating of the teeth. the fluoride mixes with the enamel, making it harder. in addition, when fluoride mixes with saliva, it can protect teeth from sugars, further reducing tooth decay. the centers for disease control (cdc) states that drinking fluoridated water provides additional protection even for people who simply brush with fluoride toothpaste. reports on the impacts of fluoridated drinking water have concluded that it reduces tooth decay by about twenty - five percent.\nwhich organizational structure does this text primarily use?\ncause - effect\ncompare - contrast

Answer

Brief Explanations:

The text first presents fluoride (cause) - added to water. Then it details the effects: strengthens enamel, mixes with saliva to protect teeth, reduces tooth decay (by 25% as per CDC). It shows a cause (fluoride in water) and its resulting effects (tooth protection, decay reduction). There is no comparing or contrasting of two different things (like two different substances' effects on teeth).

Answer:

cause - effect
