Suppose A new study suggests that drinking coffee may reduce the risk of developing Alzheimer's disease. The study followed a group of participants over 10 years, tracking their coffee consumption and cognitive function. The results showed that those who drank at least 3 cups of coffee per day were less likely to develop Alzheimer's compared to those who drank less than 1 cup per day.
Can we infer that "Drinking coffee is guaranteed to prevent Alzheimer's disease."?
