In a Kerala classroom where students struggle with English pronunciation, a teacher decides to use minimal pairs to improve their listening and speaking skills. Which language teaching method is this teacher most likely employing?

Accepted Answer

B. Audio-Lingual Method — The Audio-Lingual Method is the correct answer because it relies heavily on drills, repetition, and minimal pairs to develop listening and speaking skills, as seen in the teacher's approach. Task-Based Learning (A) focuses on completing real-world tasks, the Silent Way (C) uses non-verbal techniques like Cuisenaire rods, and the Lexical Approach (D) emphasizes learning language chunks, making them less relevant to this specific scenario.

Question 8

A high school counselor observes that many adolescents engage in impulsive, risky behaviors despite understanding the potential negative consequences. Which of the following best explains this phenomenon from a neurodevelopmental perspective?

Accepted Answer

B. The limbic system, associated with emotion and reward, matures earlier than the prefrontal cortex. — Neuroscientific research indicates that the limbic system, responsible for emotions, rewards, and impulsivity, develops and matures earlier in adolescence compared to the prefrontal cortex, which is responsible for executive functions like planning, impulse control, and risk assessment. This developmental imbalance can lead to a period where adolescents are more prone to impulsive and risky behaviors, as the emotional drive often overrides nascent rational control.

Answer

A. Adolescents have fully developed prefrontal cortices, leading them to seek thrill.

Answer

C. Hormonal imbalances in adolescence permanently impair rational decision-making.

Answer

D. Adolescents are consciously choosing to ignore risks for social acceptance.

Question 9

During muscle contraction, which ion is released from the sarcoplasmic reticulum and binds to troponin, initiating the sliding filament mechanism?

Accepted Answer

C. Calcium (Ca2+) — Calcium ions (Ca2+) are essential for muscle contraction. Upon nerve stimulation, Ca2+ is released from the sarcoplasmic reticulum and binds to troponin, causing a conformational change that exposes myosin-binding sites on the actin filaments, allowing the sliding filament mechanism to proceed. Sodium and potassium are crucial for nerve impulse transmission and muscle action potentials, and chloride helps maintain membrane potential.

Answer

A. Sodium (Na+)

Answer

B. Potassium (K+)

Answer

D. Chloride (Cl-)
