1. During the second month of pregnancy, __________.

• A. the umbilical cord first appears as a primitive body stalk
• B. touch sensitivity extends to most of the body
• C. the heart develops separate chambers
• D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.

2. During the second trimester, a white, cheeselike substance called __________ emerges on the skin.

• A. lanugo
• B. corpus luteum
• C. vernix
• D. chorion

Correct answer: C

Rationale: During the second trimester of pregnancy, a white, cheeselike substance called vernix emerges on the skin of the developing fetus. Vernix is a protective layer that helps prevent the skin from becoming waterlogged during the time in the amniotic fluid. Choice A, lanugo, is incorrect as lanugo refers to the fine, soft hair that covers the body of a fetus. Choice B, corpus luteum, is incorrect as it is a temporary endocrine structure involved in the menstrual cycle. Choice D, chorion, is incorrect as it is one of the membranes that surround the embryo and later the fetus.

3. Central to Piaget's theory is the concept of __________.

• A. imitation
• B. adaptation
• C. self-efficacy
• D. scaffolding

Correct answer: B

Rationale: Central to Piaget's theory is the concept of adaptation, which refers to the process by which individuals adjust to new information and experiences by modifying their existing cognitive structures. Piaget believed that this process of adaptation involved two key components: assimilation, where individuals incorporate new information into their existing schemas, and accommodation, where individuals adjust their schemas to fit new information. This concept highlights the dynamic nature of cognitive development and the importance of interaction between individuals and their environment in shaping intellectual growth. Choice A, 'imitation,' is incorrect as Piaget's theory focuses on how individuals actively construct their understanding of the world through their interactions with it, rather than simply imitating others. Choice C, 'self-efficacy,' is not the central concept in Piaget's theory; self-efficacy is a concept from Bandura's social cognitive theory. Choice D, 'scaffolding,' is associated with Vygotsky's sociocultural theory, not Piaget's theory.

4. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

• A. The death of a spouse causes a decline in the surviving partner's physical health.
• B. The death of a spouse is related to a decline in the surviving partner's physical health.
• C. A decline in a surviving partner's physical health can cause the death of a spouse.
• D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

5. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.

• A. heavier but shorter
• B. heavier and longer
• C. lighter but longer
• D. lighter and shorter

Correct answer: B

Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.
