1. Despite growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father, Betty is a successful, happy, and healthy adult. Betty's ability to adapt effectively in the face of threats to development is known as __________.

• A. assimilation
• B. resilience
• C. age-graded development
• D. multidimensional development

Correct answer: B

Rationale: Betty's ability to adapt effectively despite facing challenges during her childhood such as growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father demonstrates resilience. Resilience refers to the capacity to achieve positive outcomes despite adverse circumstances. Betty's successful, happy, and healthy adulthood showcases her resilience in navigating and overcoming the threats to her development. Choice A, assimilation, does not fit the context of adapting effectively to adverse circumstances. Assimilation is a cognitive process related to incorporating new information into existing schemas. Choice C, age-graded development, refers to typical developmental changes that occur in a culture at a particular age. Choice D, multidimensional development, encompasses the idea that development is influenced by multiple factors across various dimensions, which is not directly related to Betty's ability to adapt effectively despite facing challenges.

2. 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.

3. As a generation, the baby boomers are __________ than any previous mid- or late-life cohort.

• A. healthier, but less educated
• B. more educated, but less wealthy
• C. more self-focused, but less healthy
• D. healthier, better educated, and financially better off Answer: D Page Ref: 13 Box: CULTURAL INFLUENCES: The Baby Boomers Reshape the Life Course Skill Level: Remember Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Moderate

Correct answer: D

Rationale: The baby boomers are healthier, better educated, and financially better off than any previous mid- or late-life cohort. This generation has generally enjoyed higher levels of education, advancements in healthcare, and increased economic opportunities, leading to improved overall well-being compared to earlier generations.

4. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.

• A. T cells
• B. B cells
• C. telomeres
• D. antigens

Correct answer: D

Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.

5. 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.
