Explanation:

The statement about maintaining cognitive function and brain mass with exercise is supported by research. Meredith exercises and does mental activities (crosswords), so her brain is likely healthy with little shrinkage. The "True" option aligns with the idea that mental and physical exercise can maintain brain health, including grey matter, similar to how a muscle is maintained. The "False" option incorrectly assumes age alone causes significant shrinkage despite her exercise, which contradicts the given information.

Answer:

True, the brain is like a muscle and can be maintained with mental and physical exercise, including the amount of grey matter.
