Suppose A new study has found that regular consumption of green tea can help improve memory and cognitive function in older adults. The study, conducted by researchers at a university in Japan, surveyed over 500 participants aged 60 and above, and found that those who drank at least two cups of green tea per day showed significant improvements in memory tests compared to those who did not consume green tea regularly.
Can we infer that "Green tea has no impact on memory and cognitive function in older adults."? Yes, no, or maybe?
