Correct Answer: B

Rationale: The correct answer is B. Resilience plays a crucial role in mental health outcomes by enabling individuals to navigate and overcome stressors effectively, thus reducing the probability of developing mental disorders. Choice A is incorrect as resilience does have a positive impact on mental health. Choice C is incorrect as resilience is highly relevant to mental health outcomes. Choice D is incorrect because while resilience is important, it is not the only factor influencing mental health.

Correct Answer: D

Rationale: The best advice is to look for aggression toward peers as the best predictor of juvenile delinquency and dropping out of school. Option A is incorrect because being popular or a class clown doesn't necessarily indicate delinquency. Option B is incorrect as not all silent, depressed loners end up as dropouts. Option C is incorrect as research shows that early signs of aggression can predict future delinquent behavior and school dropout rates, making it feasible to intervene early.

Correct Answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

Correct Answer: B

Rationale: The correct answer is B: 'necessary cause.' A necessary cause must be present for a disorder to occur. In the context of developing chicken pox, being exposed to the virus is a necessary condition for contracting the disease. Choices A, C, and D are incorrect. A 'risk factor' increases the probability of developing a disease but is not essential for its occurrence. A 'sufficient cause' can produce the outcome on its own, which is not the case with exposure to the chicken pox virus. A 'contributory cause' adds to other causes to produce an effect, but in this scenario, exposure to the virus is crucial by itself.

Correct Answer: B

Rationale: Neurotransmitters are chemicals that influence mood, thought, and behavior, playing a significant role in mental health. Choice A is incorrect as neurotransmitters do have a notable effect on behavior. Choice C is incorrect as neurotransmitters have a major role in mental health. Choice D is incorrect as neurotransmitters do not solely determine intelligence levels.
