1. 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.

2. Men with even tiny amounts of dioxin in their bloodstream father __________.

• A. nearly twice as many girls as boys
• B. nearly three times as many boys as girls
• C. more twins and triplets than unaffected men
• D. fewer children than unaffected men

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.

3. By age 2, children __________.

• A. take turns in face-to-face interaction
• B. can infer a speaker's indirectly expressed intention
• C. adjust their speech to fit the age of their listeners
• D. adjust their speech to fit the social status of their listeners

Correct answer: C

Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.

4. Which factor fosters a more positive, coherent early self-concept?

• A. Permissive parenting
• B. A warm, sensitive parent-child relationship
• C. Authoritarian parenting
• D. Strong identification with an other-sex parent

Correct answer: B

Rationale: A warm, sensitive parent-child relationship is crucial in fostering a positive and coherent early self-concept in children. This type of relationship provides support, security, and emotional guidance, helping children develop a strong sense of self-worth and self-identity. Permissive parenting (Choice A) may lead to confusion and inconsistency in discipline, impacting the child's self-concept negatively. Authoritarian parenting (Choice C), characterized by strict rules and a lack of warmth, can result in a child feeling insecure and having a negative self-concept. Strong identification with an other-sex parent (Choice D) may influence gender identity development but may not directly impact the early self-concept in the same way a warm and sensitive parent-child relationship does.

5. Longitudinal research can identify common patterns as well as individual differences in development because the investigator __________.

• A. studies groups of participants differing in age at the same point in time
• B. randomly assigns participants to treatment conditions
• C. tracks the performance of each person over time
• D. conducts quasi-experiments, comparing conditions that already exist

Correct answer: C

Rationale: Longitudinal research involves tracking the performance of each person over time. By doing so, researchers can observe common patterns in development among a group of individuals and also identify individual differences in how each person progresses over time. This methodology allows researchers to gather data on the same individuals repeatedly, offering insights into how development unfolds over the lifespan. Choices A, B, and D are incorrect because longitudinal research focuses on observing individuals over time rather than studying groups at a single point, randomly assigning participants to treatments, or conducting quasi-experiments.
