1. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.

• A. is harmful only when combined with other teratogens
• B. can increase the risk of childhood cancer
• C. rarely causes lasting damage
• D. is safe during the last trimester

Correct answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.

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. Who is generally regarded as the founder of the child study movement?

• A. Charles Darwin
• B. G. Stanley Hall
• C. Alfred Binet
• D. Sigmund Freud

Correct answer: B

Rationale: G. Stanley Hall is generally regarded as the founder of the child study movement. He established the first American research laboratory dedicated to child psychology and education, helping to pioneer the scientific study of child development. Choices A, C, and D are incorrect as they were not primarily associated with founding the child study movement. Charles Darwin is known for his contributions to the theory of evolution, Alfred Binet is famous for developing the first intelligence test, and Sigmund Freud is renowned for his work in psychoanalysis.

4. Fraternal twins are ____________.

• A. genetically identical
• B. no more alike than ordinary siblings
• C. less common than other types of multiple offspring
• D. less likely with each additional birth

Correct answer: B

Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.

5. According to the continuous view of development, the difference between the immature and the mature is simply one of amount or complexity.

• A. nature
• B. discontinuous
• C. nurture
• D. continuous

Correct answer: D

Rationale: The correct answer is D. According to the continuous view of development, the difference between the immature and the mature is seen as simply one of amount or complexity. This view suggests that development is a gradual and continuous process where individuals steadily acquire new abilities without abrupt changes or stages. Choices A, B, and C are incorrect because nature, discontinuous, and nurture do not align with the description provided in the question. Nature typically refers to genetic or biological factors, discontinuous implies stages or abrupt changes, and nurture relates to environmental influences, none of which are synonymous with the continuous view of development.
