English Idioms — Choose the correct meaning. Sentence (corrected punctuation): Do not trust a man who blows his own trumpet.

Introduction / Context:
The idiom “to blow one’s own trumpet” (also “to toot one’s own horn”) is common in conversational and media English. It describes self-promotion or boasting about one’s achievements. The caution “Do not trust …” suggests that such self-advertising may be unreliable or distasteful.

Given Data / Assumptions:

• Idiom: blows his own trumpet.
• Pragmatic cue: admonitory tone (“Do not trust…”).
• We must map the image to the intended social behavior.

Concept / Approach:
Playing one’s own fanfare is a metaphor for publicizing oneself. The cleanest paraphrase is “praises himself,” which captures boasting. Options that refer to praising others or scolding others fail to align with the reflexive, self-directed nature of the idiom.

Step-by-Step Solution:

Verification / Alternative check:
Replace: “Do not trust a man who praises himself.” This keeps the cautionary tone and social judgment intact, matching idiomatic English usage across exam prep texts and newspapers.

Why Other Options Are Wrong:

• flatters: Usually directed at others; not reflexive here.
• praises others: Opposite direction.
• admonishes others: Criticizes/scolds; unrelated.

Common Pitfalls:
Confusing “flattery” (praising others) with self-praise. The core cue is “his own,” signaling a reflexive act of boasting.

Final Answer:
praises himself
