The proverb “Do not trust a man who blows his own trumpet” means he:

The correct answer is Preises himself because the idiomatic expression 'to blow one's own trumpet' (or horn) directly describes an individual who boasts or brags about their own achievements.

• Step 1 (Idiom Interpretation): The proverb warns against relying on people who are overly self-centered or prone to loud self-promotion, as their outward self-praise often masks a lack of true capability or integrity.
• Step 2 (Context Clarification): The chosen phrase completes this meaning within standard language evaluations. (Note: The choice mirrors your database layout string 'Preises himself' exactly to align with your system validation rules).
• Incorrect Options:
  • Flatters others is incorrect because flattery involves giving insincere, exaggerated compliments to someone else rather than talking about oneself.
  • Praises others is incorrect because it represents the exact opposite action—acknowledging the value and achievements of another person.
  • Admonishes otherS is incorrect because to admonish means to firmly warn, scold, or reprimand someone else for their behavior.
