Which word means 'Someone who shows off learning'?

• A. Perfunctory
• B. Pedant
• C. Perfidious
• D. Obstinate

Answer: (B)

The concept here is identifying a term for someone who flaunts their learning. The word that fits best is pedant. A pedant is someone who overemphasizes formal knowledge and correctness, often correcting others or focusing on trivial details to display their learning. This negative sense distinguishes it from simply being learned; the idea is the show of knowledge rather than genuine understanding.

Perfunctory describes something done with minimal effort or care, not about displaying learning. Perfidious means deceitful or treacherous. Obstinate means stubborn and unwilling to change one's mind. These don’t capture the sense of someone who parades their knowledge as a form of showmanship the way pedant does.
