1. The force of blood flowing through the __________ keeps it firm.

• A. amnion
• B. umbilical cord
• C. yolk sac
• D. embryonic disk

Correct answer: B

Rationale: The force of blood flowing through the umbilical cord keeps it firm. The umbilical cord is the connection between the placenta and the fetus, providing essential nutrients and oxygen to the developing baby. Blood flow through the umbilical cord helps maintain its structure and function throughout the prenatal period. Choices A, C, and D are incorrect as they do not play a role in providing nutrients and oxygen to the developing baby or in maintaining its firmness.

2. Which statement about epidural analgesia is true?

• A. It numbs the entire lower half of the body.
• B. It limits pain reduction to the pelvic region.
• C. It strengthens uterine contractions.
• D. It shortens the length of labor.

Correct answer: B

Rationale: The correct statement about epidural analgesia is that it limits pain reduction to the pelvic region by blocking nerve signals from that specific area, providing pain relief during labor and delivery. Choice A is incorrect because epidural analgesia does not numb the entire lower half of the body. Choice C is incorrect because epidural analgesia does not strengthen uterine contractions; in fact, it may sometimes weaken them. Choice D is incorrect because epidural analgesia does not shorten the length of labor; it can sometimes prolong labor.

3. Which sense is the least-developed in newborn babies?

• A. Taste
• B. Sound
• C. Vision
• D. Touch

Correct answer: C

Rationale: Vision is the least-developed sense in newborn babies. While newborns can see, their vision is not as developed as their other senses at birth. Taste, sound, and touch are more developed senses in newborns compared to vision. Over time, through visual stimulation and experiences, a baby's vision gradually improves and develops.

4. Alfred Binet and Theodore Simon __________.

• A. wrote the first book of its time on aging
• B. were among the first to make child development knowledge meaningful to parents
• C. regarded development as a maturational process
• D. constructed the first successful intelligence test Answer: D Page Ref: 14 Skill Level: Remember Topic: Scientific Beginnings Difficulty Level: Moderate

Correct answer: D

Rationale: Alfred Binet and Theodore Simon constructed the first successful intelligence test, known as the Binet-Simon scale, in an effort to measure a child's intelligence level. This test was groundbreaking at the time and laid the foundation for the development of future intelligence tests.

5. The two main types of designs used in all research on human behavior are __________ and __________.

• A. observational; experimental
• B. correlational; experimental
• C. observational; correlational
• D. variable; observational Answer: B Page Ref: 31 Skill Level: Remember and limitations of each. Topic: Studying Development Difficulty Level: Easy

Correct answer: B

Rationale: The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research examines the relationship between two or more variables without establishing causation, while experimental research involves manipulating one variable to observe the effect on another variable. These two types of designs are fundamental in understanding and studying human behavior.
