Which adjective best describes Hoshino's speech?

• A. Polite
• B. Formal
• C. Vulgar
• D. Loud

Answer: (C)

Hoshino’s speech is best described as vulgar because his language is crude, earthy, and full of slang and coarse expressions that reflect a working-class, unrefined style. He speaks bluntly and without polish, often pressing into topics with a directness that isn’t polite or formal. This contrasts with polite speech, which would emphasize courtesy and consideration, and formal speech, which uses careful grammar and reserved phrasing. Loud would focus on volume, which isn’t the central characteristic here; the defining feature is the rough, uncensored register of his words. So, vulgar captures the tone and register of how he talks.
