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. Breastfeeding for just a few weeks ________.

• A. is a rare practice among American women
• B. leads directly to later obesity
• C. is not helpful because, in the beginning, breastfeeding causes constipation
• D. offers some protection against respiratory and intestinal infections

Correct answer: D

Rationale: Breastfeeding for even a short period offers infants protection against respiratory and intestinal infections. Choice A is incorrect because breastfeeding is not a rare practice among American women. Choice B is incorrect as there is no direct link between breastfeeding for a few weeks and later obesity. Choice C is incorrect as breastfeeding does not cause constipation in infants; in fact, it can help prevent constipation.

3. Newborn infants who are brain damaged or who have experienced birth trauma often __________.

• A. display disturbed REM-NREM sleep cycles
• B. cry less than those with no brain functioning problems
• C. spend about 20 percent of their total sleep time in REM sleep
• D. have very low or inaudible cries

Correct answer: A

Rationale: Newborn infants who are brain damaged or who have experienced birth trauma often display disturbed REM-NREM sleep cycles. This disruption in the sleep cycle can be a sign of neurological issues and can impact the newborn's overall health and development. Choice B is incorrect because infants with brain damage or birth trauma may actually cry more due to their discomfort or neurological issues. Choice C is incorrect because spending about 20 percent of total sleep time in REM sleep is not necessarily specific to brain-damaged or birth-traumatized infants. Choice D is incorrect because having very low or inaudible cries is not a common characteristic associated with brain damage or birth trauma in infants.

4. Which statement about a blastocyst is true?

• A. It consists of a single cell.
• B. It is a structure that feeds the developing organism.
• C. Between the seventh and ninth days, it burrows deep into the uterine lining.
• D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

5. Tammy's father is an exceptional gymnast. When Tammy was just a toddler, her father believed that Tammy already showed great promise as a gymnast. Tammy's father probably believes that athletic ability is mostly determined by __________.

• A. nurture
• B. stages
• C. nature
• D. early experiences

Correct answer: C

Rationale: Tammy's father likely believes that athletic ability is mostly determined by nature because he believes she showed great promise at a young age, indicating a natural talent or genetic predisposition towards gymnastics. This suggests that he attributes Tammy's abilities to her inherent qualities rather than her upbringing or experiences (nurture). While stages and early experiences can play a role in skill development, in this context, the emphasis is on innate abilities, making 'nature' the most suitable choice.
