One-word substitution (vocabulary): Choose the correct term for “a writing style in which a writer makes a display of his knowledge.” Select the single best word that matches the stylistic description.

Reasoning through options Pedantic — overly concerned with minute details and the display of academic knowledge; textbook-perfect match. Verbose — uses too many words; wordiness, not necessarily knowledge display. Pompous — self-important tone; not specifically about scholarly showiness. Ornate — highly decorated/elaborate style; again, not necessarily about knowledge display.

Final Answer Pedantic
