Suppose a new study claims that eating chocolate every day can improve memory and cognitive function. The study involved participants who consumed a small piece of dark chocolate daily for three months. Researchers found that those who ate chocolate showed significant improvement in memory tests compared to those who did not. However, critics argue that the study did not control for other factors that may have influenced the results.
Can we infer that "Eating chocolate daily has a negative impact on memory and cognitive function"? Yes, no, or maybe?
