Question

Which of the following is suggested by your authors as helping to substantially improve cognitive health?

A. physical exercise
B. a diet high in beta-amyloids
C. drinking one or two glasses of red wine at least twice a week
D. the cessation of cigarette smoking

Answer 1

Physical exercise is suggested by the authors as a way to substantially improve cognitive health. Regular exercise has been shown to reduce the risk of neurodegenerative disorders and enhance cognitive function in older adults. So, the correct answer is option A.

Step-by-step explanation:

The authors suggest that physical exercise can substantially improve cognitive health. Studies have shown that regular exercise can reduce the risk of developing neurodegenerative disorders such as dementia and enhance cognitive function in older adults.

Exercise promotes neurogenesis, the growth of new brain cells, and increases blood flow and oxygen availability to the brain. These benefits can lead to improvements in memory, learning, attention, and other cognitive functions. So, the correct answer is option A.

Answer 2

Physical exercise is the factor suggested by the authors as substantially improving cognitive health, due to its numerous benefits for brain function and cognition. Option A is correct.

Step-by-step explanation:

Among the options provided, physical exercise is suggested by the authors as helping to substantially improve cognitive health. Exercise, specifically aerobic exercise, has been extensively researched and shown to have a positive impact on cognitive function. Regular physical activity increases blood flow and oxygen to the brain, promotes the growth of new brain cells and neuronal pathways, and enhances levels of neurotransmitters like serotonin. These benefits contribute to enhanced memory retention, information processing, and overall cognition.

Conversely, a diet high in beta-amyloids is not advised as these proteins can aggregate in the brain and are associated with Alzheimer's disease. Drinking wine in moderation may have some health benefits but its effect on cognitive health is not as significant as regular exercise. Lastly, the cessation of cigarette smoking is indeed beneficial for overall health and may help in improving cognitive function, but it is not the most referenced factor in the provided literature when it comes to cognitive improvement as the focus here is on the proactive benefits of physical exercise.
