1. Brain growth is especially dramatic during __________, when the brain more than doubles in size.

• A. the first year
• B. the second year
• C. middle childhood
• D. adolescence

Correct answer: A

Rationale: Brain growth is especially dramatic during the first year of life when the brain more than doubles in size. This period is characterized by rapid neural development and growth. The brain doesn't double in size during the second year, making choice B incorrect. Middle childhood and adolescence do not represent periods where the brain more than doubles in size, making choices C and D incorrect, respectively.

2. What is the longest stage of labor?

• A. Delivery of the baby
• B. Delivery of the placenta
• C. Dilation and effacement of the cervix
• D. Release of epinephrine and cortisol

Correct answer: C

Rationale: The correct answer is C: Dilation and effacement of the cervix. This stage can last for hours, especially for first-time mothers, as the cervix needs to dilate and efface to allow for the baby's passage through the birth canal. Once the cervix is fully dilated and effaced, the woman can begin pushing during the second stage of labor to deliver the baby. The delivery of the baby itself is usually a shorter process compared to the time taken for the cervix to dilate and efface. Choices A, B, and D are incorrect because they represent other stages within the labor process that come after the dilation and effacement of the cervix.

3. Children in middle childhood are in Piaget's _______ stage, which extends from about 7 to 11 years.

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. formal operational

Correct answer: C

Rationale: The correct answer is C: concrete operational. During the concrete operational stage, children start to engage in logical thinking about concrete events. This stage typically occurs between the ages of 7 to 11 years. Choices A, B, and D are incorrect. The sensorimotor stage (choice A) is the first stage in Piaget's theory, occurring from birth to about 2 years old. The preoperational stage (choice B) follows the sensorimotor stage and occurs roughly from ages 2 to 7 years. The formal operational stage (choice D) is the final stage in Piaget's theory, where abstract thinking and hypothetical reasoning develop, usually beginning around age 11.

4. Developmental science is __________ because it has grown through the combined efforts of people from many fields of study.

• A. interdisciplinary
• B. empirical
• C. applied
• D. theoretical

Correct answer: A

Rationale: Correct answer: Developmental science is interdisciplinary because it integrates knowledge from multiple fields like psychology, biology, and sociology. The term 'empirical' refers to information gained from observation or experimentation, which is not the focus of this question. 'Applied' and 'theoretical' do not capture the essence of developmental science requiring inputs from various disciplines.

5. __________ may heighten the effects of a high-fat diet.

• A. Sex hormones
• B. Over-the-counter medications
• C. Free radicals
• D. Low body weight

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.
