1. What is one strength of the cross-sectional design?

Correct answer: C

Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.

2. Which statement about the human immunodeficiency virus (HIV) is true?

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.

3. Dr. Bigelow is interested in studying musical prodigies. Which method is best suited for this type of research?

Correct answer: C

Rationale: A case study would be the best method for Dr. Bigelow to study musical prodigies. In a case study, the researcher can closely examine and analyze the unique characteristics, abilities, and behaviors of individual subjects. This method allows for in-depth exploration of a specific phenomenon, making it ideal for investigating exceptional cases such as musical prodigies. Naturalistic observation involves observing subjects in their natural environment without interference, which may not provide the detailed insights needed for studying musical prodigies. Clinical interviews focus on gathering information through structured questioning, not ideal for studying unique talents. Structured interviews involve asking a set of predetermined questions, which may not allow for the depth of exploration required for studying musical prodigies.

4. New evidence suggests that __________.

Correct answer: D

Rationale: The correct answer is D because the statement aligns with the concept of reciprocal influences in human development. The new evidence suggests that individuals are not only influenced by the contexts in which they develop but also contribute to shaping those contexts. This idea highlights the dynamic and interactive nature of human development, emphasizing the bidirectional relationship between individuals and their environments.

5. People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to __________ influences.

Correct answer: B

Rationale: People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to history-graded influences. These influences refer to the events and conditions that are common to a particular historical era and can significantly shape the development and experiences of individuals who live through them. The post-World War II era, economic prosperity, and social changes during the baby boom period are examples of historical events that have had a lasting impact on this generation.
