Correct Answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

Correct Answer: D

Rationale: According to the lifespan perspective, no single period is considered supreme in its impact on the life course. Each stage of life, from prenatal period through adulthood, plays a significant role in shaping an individual's development. Therefore, the correct answer is 'D: no age period.' Choices A, B, and C are incorrect because the lifespan perspective emphasizes that all stages are important and contribute uniquely to an individual's life course.

Correct Answer: A

Rationale: According to Erikson, when parents are over- or undercontrolling, the outcome is a child who feels forced and shamed. This is because overly controlling parents can make the child feel inadequate, leading to a sense of shame and doubt. Choice B, 'acts competently on his own,' is incorrect because overcontrolling parents hinder the child's ability to act independently. Choice C, 'asserts his independence,' is incorrect because overcontrolling parents can actually suppress the child's independence. Choice D, 'feels self-confident,' is incorrect because overcontrolling parenting can undermine the child's confidence and lead to feelings of inadequacy.

Correct Answer: B

Rationale: The correct answer is 'Successful.' Successful aging encompasses achieving desirable outcomes and coping effectively with life's challenges and losses. 'Optimal' could imply a focus solely on achieving the best outcomes without considering challenges and losses. 'Peerless' means unmatched or unrivaled, which does not address coping with challenges. 'Capital' is related to wealth or assets and is not suitable in the context of aging and coping with life's difficulties.

Correct Answer: D

Rationale: The correct answer is D: 'can lead to cognitive deterioration.' Depression, particularly in older adults, can significantly impair cognitive function, leading to further mental health challenges. Choices A, B, and C are incorrect. Depression does not necessarily decline with age, treatment coverage may vary, and depression can indeed be related to physical illness or pain.
