Suppose [England], Sep 30 (Reuters): A new study from the University of Manchester has found that regular consumption of green tea can help improve brain function and memory in older adults. The study, which involved 200 participants over the age of 60, found that those who drank green tea daily showed significant improvements in cognitive tests compared to those who did not consume green tea. Researchers believe that the antioxidants and caffeine in green tea may play a role in these cognitive benefits.
Can we infer that "All participants in the study were over the age of 70"? Yes, no, or maybe?
