1. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.

• A. long-lived predatory fish; mercury
• B. freshwater fish; lead
• C. long-lived predatory fish; polychlorinated biphenyls
• D. freshwater fish; radiation

Correct answer: A

Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.

2. Which statement describes a limitation of the clinical method?

• A. It may not yield observations typical of participants’ behavior in everyday life.
• B. Researchers cannot control conditions under which participants are observed.
• C. The findings cannot be applied to individuals other than the participant.
• D. It does not usually yield rich, descriptive insights into factors that affect development. Answer: C Page Ref: 30 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate

Correct answer: C

Rationale: The statement that describes a limitation of the clinical method is that the findings cannot be applied to individuals other than the participant. The clinical method typically involves in-depth studies of individual participants, which may limit generalizability to a broader population. This means that the findings from a clinical study may not be applicable to other individuals who are not directly involved in the study.

3. In an investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early __________ than children who experienced a full-length prenatal period.

• A. showed lower reading and math scores at a third-grade follow-up
• B. were less likely to suffer from childhood obesity
• C. were less likely to suffer from neurological impairments
• D. showed higher language and social/emotional scores in early childhood

Correct answer: A

Rationale: In the investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early showed lower reading and math scores at a third-grade follow-up compared to children who experienced a full-length prenatal period. This suggests that being born slightly premature can have an impact on cognitive development, leading to educational challenges later on. Choices B, C, and D are incorrect because the study specifically highlighted lower reading and math scores, not a reduced likelihood of suffering from childhood obesity or neurological impairments, or improved language and social/emotional scores in early childhood.

4. According to Erikson, if the psychological conflict of adolescence is resolved negatively, a young person experiences __________.

• A. mistrust
• B. isolation
• C. inferiority
• D. role confusion

Correct answer: D

Rationale: Erikson's theory of psychosocial development states that during adolescence, individuals face the conflict of identity vs. role confusion. If this conflict is resolved negatively, adolescents experience role confusion. Role confusion occurs when adolescents fail to develop a clear sense of identity, leading to uncertainty about their future roles. Choices A, B, and C are incorrect because they correspond to earlier stages of Erikson's stages of psychosocial development (mistrust corresponds to infancy, isolation to early adulthood, and inferiority to middle childhood), not adolescence.

5. Among all Western nations, which country has the highest percentage of extremely poor children?

• A. the United States
• B. Canada
• C. Germany
• D. France

Correct answer: A

Rationale: The correct answer is 'the United States.' According to the information provided, the United States has the highest percentage of extremely poor children among Western nations. This is supported by the extract, which states that the United States leads in this aspect. Choices B, C, and D are incorrect as the question specifically asks for the country with the highest percentage of extremely poor children among Western nations, which is the United States.
