Match each advanced vocabulary word in the left column with the word most nearly opposite in meaning (antonym) in the right column based on standard academic English usage.
- Perspicacious (demonstrating keen insight and quick mental discernment)Obtuse
- Supercilious (behaving with haughty disdain or arrogant superiority)Deferential
- Recalcitrant (obstinately defiant of authority or discipline)Compliant
- Ephemeral (lasting for a very brief, fleeting duration)Enduring
Answer
Perspicacious matches with Obtuse; Supercilious matches with Deferential; Recalcitrant matches with Compliant; Ephemeral matches with Enduring.
Each left-column vocabulary term is paired precisely with its true semantic opposite: 'perspicacious' (keen/sharp) contrasts with 'obtuse' (dull/insensitive); 'supercilious' (haughty/arrogant) contrasts with 'deferential' (respectful/humble); 'recalcitrant' (unruly/defiant) contrasts with 'compliant' (submissive/obedient); and 'ephemeral' (transient/short-lived) contrasts with 'enduring' (lasting/permanent).
