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: 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: Object-relations theory is a psychodynamic theory that focuses on how individuals interact with others and their internalized relationships. Choice A is incorrect because object-relations theory goes beyond observable behaviors to explore internalized relationships. Choice C is incorrect because object-relations theory does not primarily emphasize cognitive processes. Choice D is incorrect because object-relations theory is not a cognitive-behavioral theory focused on changing thought patterns.

Correct Answer: B

Rationale: The correct answer is B. Authoritative parents are warm and communicative while also setting firm limits, creating a balanced and nurturing environment. Authoritarian parents, on the other hand, are controlling, less communicative, and tend to set strict rules without much room for discussion. This approach may lead to children becoming irritable and moody due to the lack of warmth and excessive control. Choices A and C incorrectly mix up the characteristics of authoritative and authoritarian parenting. Choice D, although mentioning irritable children, does not accurately capture the key differences between authoritative and authoritarian parenting styles.

Correct Answer: A

Rationale: In understanding abnormal behavior, it is crucial to differentiate between necessary, sufficient, and contributory causes. Necessary causes are those that are required for a disorder to develop, meaning that without them, the disorder would not occur. However, their presence does not guarantee the occurrence of the disorder. Sufficient causes, on the other hand, are those that alone can guarantee the development of a disorder, but they are not the only factors that can lead to it. Contributory causes are factors that increase the likelihood of a disorder but are not essential on their own nor do they guarantee the disorder. Therefore, choice A is the correct answer as it accurately describes the role of necessary causes in the development of abnormal behavior. Choices B, C, and D are incorrect as they misrepresent the definitions and roles of sufficient and contributory causes in causing abnormal behavior.
