For this question, choose the option opposite in meaning to the word or phrase in italics A cup of coffee invigorated him

Analyze the question: We need the word opposite in meaning to "invigorated" in the sentence "A cup of coffee invigorated him."

Explain the concept: To invigorate means to give strength, energy, or vitality to someone. Its antonym will therefore mean to make someone weak or drain their energy.

Go through the options:

• A. destroyed: This means to ruin or end something completely. It is not the direct opposite of giving energy, because destroying is about ruining things, not about weakening a person's strength.
• B. energized: This is a synonym of invigorated, so it is the opposite of what we want.
• C. angered: This relates to emotion, not energy or strength, so it has no connection.
• D. debilitated: This means to weaken or make feeble. It is the direct opposite of giving strength and vigour.

Answer: The correct option is D. debilitated.

Tip: In "opposite meaning" questions, first find the synonym in the options (here, energized) and eliminate it, since it is the trap. Then pick the word that points in the reverse direction. You can also remember that debilitate shares a root with debility (weakness), which is the opposite of vigour.
