Question 4

Adolescent risk-taking behavior, such as experimenting with substances or reckless driving, is often attributed to a developmental mismatch in the brain. Which of the following best describes this mismatch?

Accepted Answer

B. Rapid development of the limbic system (reward center) preceding the full maturation of the prefrontal cortex (judgment center). — The limbic system, responsible for emotions and reward processing, develops rapidly during adolescence, leading to increased sensation-seeking. However, the prefrontal cortex, crucial for judgment, impulse control, and long-term planning, matures later, creating a temporary imbalance that can contribute to risk-taking behaviors. The prefrontal cortex is not fully developed, and the cerebellum and brainstem play different roles.

Answer

A. Fully developed prefrontal cortex but underdeveloped limbic system.

Answer

C. Complete maturation of the cerebellum leading to impulsive actions.

Answer

D. Underdevelopment of the brainstem affecting emotional regulation.

Question 6

Which of the following factors primarily determines the rate of gas exchange (oxygen and carbon dioxide) across the alveolar-capillary membrane?

Accepted Answer

B. Partial pressure gradient of gases — The rate of gas exchange across the alveolar-capillary membrane is directly proportional to the partial pressure gradient of oxygen and carbon dioxide. Gases move from an area of higher partial pressure to an area of lower partial pressure. Blood pH primarily affects hemoglobin's affinity for oxygen, while lung compliance and tidal volume influence ventilation, not the direct rate of diffusion.

A. Blood pH

Answer

C. Lung compliance

Answer

D. Tidal volume

Question 9

A teacher observes that her students, despite knowing grammar rules, struggle to use English effectively in spontaneous conversations. She wants to adopt a method that prioritizes meaningful interaction and fluency over strict grammatical accuracy in the initial stages. Which language teaching method would be most appropriate for her goal?

Accepted Answer

C. Communicative Language Teaching — Communicative Language Teaching (CLT) emphasizes the development of communicative competence, focusing on meaningful interaction and fluency in real-life contexts. It prioritizes the ability to convey meaning effectively, even if with some grammatical errors, over strict accuracy in initial stages. Grammar-Translation and Audio-Lingual methods typically prioritize accuracy and form, while the Direct Method focuses on natural language acquisition but often still emphasizes correct usage through demonstration.

Answer

A. Grammar-Translation Method

Answer

B. Audio-Lingual Method

Answer

D. Direct Method
