1. In the eighth month of pregnancy, what typically happens?

• A. fetal growth doubles
• B. neuron production increases
• C. the eyes, ears, nose, jaw, and neck form
• D. lanugo typically is shed

Correct answer: D

Rationale: In the eighth month of pregnancy, lanugo typically is shed. Lanugo is the fine, downy hair that covers a fetus's body to help regulate body temperature while in the womb. By the eighth month, many fetuses shed this hair as they prepare for birth. Choices A, B, and C are incorrect because fetal growth doubling, neuron production increasing, and the formation of eyes, ears, nose, jaw, and neck occur in earlier stages of pregnancy, not specifically in the eighth month.

2. What is the function of the corpus luteum?

• A. is where fertilization usually takes place
• B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
• C. is one of two long, thin structures that lead to the hollow, softly lined uterus
• D. is one of two walnut-sized organs located deep inside a woman's abdomen

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.

3. Self-esteem takes on a hierarchical structure in __________.

• A. toddlerhood
• B. preschool
• C. middle childhood
• D. adolescence

Correct answer: C

Rationale: In middle childhood, self-esteem becomes more differentiated and organized into a hierarchy based on various domains of competence. This period marks a time when children start to compare their abilities in different areas, such as academic performance, social skills, and physical abilities. Toddlerhood and preschool years are characterized by the development of basic self-awareness and self-concept, but self-esteem hierarchy typically emerges later in middle childhood and further solidifies in adolescence as individuals navigate complex social dynamics and personal identities.

4. Theorists who contend that powerful negative events in the first few years cannot be fully overcome by later, more positive ones emphasize __________.

• A. plasticity
• B. stability
• C. nurture
• D. discontinuity

Correct answer: B

Rationale: Theorists who emphasize stability argue that powerful negative events early in life cannot be completely overcome by later, more positive experiences. They believe that early experiences have a lasting impact on development and are not easily erased or reversed by subsequent events. This perspective contrasts with the idea of plasticity, which suggests that development can be influenced by experiences at any point in life, and that individuals have the capacity for change and growth throughout the lifespan. 'Nurture' does not directly address the concept of overcoming negative events, while 'discontinuity' refers to developmental stages being separate and distinct, not the idea that negative events early in life persist despite later positive experiences.

5. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.

• A. naturalistic observation
• B. case study
• C. natural experiment
• D. field experiment

Correct answer: D

Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.
