➤ How did Smith suggest addressing the imbalance between masters and workers?
Smith favored competitive markets, legal equality, and limits on monopolies and special privileges. He argued removing trade restrictions and political favors would reduce employers’ artificial advantages. He trusted market competition and impartial law to weaken collusion rather than endorsing protected guilds or heavy-handed controls that reinforced master dominance.

➤ Is selenium involved in superoxide dismutase function?
No. Selenium is not a cofactor for superoxide dismutase. Instead, selenium is essential for selenoproteins such as glutathione peroxidases and thioredoxin reductases, which reduce hydrogen peroxide and lipid peroxides and help maintain cellular redox balance downstream of SOD activity.

➤ Why is Piaget’s theory important for teaching and assessment?
Piaget’s theory guides educators to match instruction to developmental levels. Teachers use concrete materials for younger learners, promote exploration, and avoid expecting abstract reasoning too early. Assessment emphasizes observing problem-solving and conceptual change. Scaffolding and hands-on tasks support accommodation and the transition to higher cognitive operations.
