1. Dr. Anderson wants to conduct a study to determine the cause-and-effect relationship between domestic violence and anger in children. Dr. Anderson should use a(n) __________ design.

• A. structured
• B. observational
• C. correlational
• D. experimental

Correct answer: D

Rationale: Dr. Anderson should use an experimental design to determine the cause-and-effect relationship between domestic violence and anger in children. In an experimental design, the researcher manipulates the independent variable (in this case, exposure to domestic violence) to observe its effect on the dependent variable (anger in children). This design allows for the establishment of a cause-and-effect relationship by controlling for other variables that may influence the outcomes. Observational design (Choice B) involves observing subjects in their natural environment without interference, correlational design (Choice C) examines the relationship between variables without manipulating them, and structured design (Choice A) typically refers to a study with predetermined procedures and data collection methods, which may not be suitable for establishing cause-and-effect relationships.

2. Nine-year-old Krista gives part of her allowance to charity and collects canned goods for the food bank through her scout troop. Krista is developing __________.

• A. pride
• B. empathy
• C. guilt
• D. inferiority

Correct answer: B

Rationale: The correct answer is B: empathy. Empathy is the ability to understand and share the feelings of others, which is a crucial social development in childhood. In this scenario, Krista's actions of giving to charity and collecting goods for the food bank demonstrate her growing empathy towards those in need. Choice A, pride, does not capture the essence of understanding and sharing others' feelings. Choice C, guilt, is not appropriate as there is no indication that Krista feels guilty about her actions. Choice D, inferiority, is unrelated to the positive behavior displayed by Krista.

3. 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.

4. Unlike adults, newborn babies __________.

• A. have a limited sense of smell
• B. see nearby objects most clearly
• C. prefer unfamiliar voices to familiar ones
• D. see unclearly across a wide range of distances

Correct answer: B

Rationale: Unlike adults, newborn babies see nearby objects most clearly. This is due to the fact that newborns have a limited ability to focus their eyes on objects that are farther away. Their visual acuity is not fully developed at birth, leading to clearer vision of objects situated at a close distance. Choice A is incorrect because newborn babies have a well-developed sense of smell. Choice C is incorrect as newborns typically show a preference for familiar voices, such as their mother's voice. Choice D is incorrect as newborns do not see unclearly across a wide range of distances; rather, their vision is clearer for nearby objects.

5. The third stage of labor lasts about __________.

• A. 5 to 10 minutes
• B. 20 to 50 minutes
• C. 4 to 6 hours
• D. 12 to 14 hours

Correct answer: A

Rationale: The correct answer is A: 5 to 10 minutes. The third stage of labor typically lasts about 5 to 10 minutes. This stage begins after the baby is born and ends when the placenta is delivered. It is the shortest stage of labor compared to the first and second stages. Choice B, 20 to 50 minutes, is incorrect as it is too long for the duration of the third stage. Choice C, 4 to 6 hours, and Choice D, 12 to 14 hours, are also incorrect as they are significantly longer than the actual duration of the third stage of labor.
