1. 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.

2. In the last weeks of pregnancy, __________.

• A. the fetus usually loses weight
• B. most fetuses assume an upside-down position
• C. fetal growth increases dramatically
• D. the fetus relies on its own well-developed immune system

Correct answer: B

Rationale: In the last weeks of pregnancy, most fetuses assume an upside-down position known as the head-down position or vertex presentation. This position is ideal for a smoother labor and delivery process as it helps the baby move through the birth canal. Fetal growth has already slowed down at this stage, so option C is incorrect. Option A is inaccurate as the fetus typically gains weight in the final weeks. Option D is incorrect because the fetus relies on the mother's immune system while in the womb.

3. Today, Albert Bandura's theory stresses the importance of __________.

• A. behavior modification
• B. punishment
• C. cognition
• D. reinforcement

Correct answer: C

Rationale: Albert Bandura's theory stresses the importance of cognition. Bandura's Social Learning Theory emphasizes the role of cognitive processes in learning and behavior, including the influence of observation, modeling, and mental representations. This theory highlights how individuals learn through observation and imitation of others, as well as their own thought processes and beliefs. Choices A, B, and D are incorrect because while behavior modification, punishment, and reinforcement are aspects related to learning theories, they are not the primary focus of Bandura's theory, which revolves around cognition and social learning.

4. Newborn infants who are brain damaged or who have experienced birth trauma often __________.

• A. display disturbed REM-NREM sleep cycles
• B. cry less than those with no brain functioning problems
• C. spend about 20 percent of their total sleep time in REM sleep
• D. have very low or inaudible cries

Correct answer: A

Rationale: Newborn infants who are brain damaged or who have experienced birth trauma often display disturbed REM-NREM sleep cycles. This disruption in the sleep cycle can be a sign of neurological issues and can impact the newborn's overall health and development. Choice B is incorrect because infants with brain damage or birth trauma may actually cry more due to their discomfort or neurological issues. Choice C is incorrect because spending about 20 percent of total sleep time in REM sleep is not necessarily specific to brain-damaged or birth-traumatized infants. Choice D is incorrect because having very low or inaudible cries is not a common characteristic associated with brain damage or birth trauma in infants.

5. What is a major strength of the longitudinal design?

• A. Examine relationships between early and later behaviors
• B. Collect a large amount of data in a short time span
• C. Explore similarities among children of different cohorts
• D. Study participants differing in age at the same point in time

Correct answer: A

Rationale: A major strength of the longitudinal design is that researchers can examine relationships between early and later behaviors. This design allows researchers to observe and track changes in the same participants over an extended period of time, providing valuable insights into developmental trajectories and how behaviors are connected across different stages of life. Choice B is incorrect because longitudinal studies track changes over time, not necessarily collect a large amount of data in a short time span. Choice C is incorrect as it refers to cross-sectional studies rather than longitudinal studies. Choice D is incorrect as it describes a cross-sectional design where participants of different ages are studied at the same time.
