Chief Money-Miss-Road is a sitting duck

Analyze the question: The phrase "sitting duck" is an idiom. It means a person or thing that is easy to attack or take advantage of, because they are defenseless and exposed. We need the word that means the opposite.

Explain the concept: This is an idiom-antonym question. Do not read the phrase literally (a duck sitting down). First find the idiom's real meaning, then look for its opposite.

Solution:

• Meaning of "sitting duck": an easy target, so vulnerable or defenseless.
• Check each option: • A. vulnerable: This is a synonym, not an opposite. Wrong. • B. invincible: This means impossible to defeat or harm. It is the exact opposite of being an easy target. Correct. • C. lazy: This describes a lack of effort, not the opposite of being an easy target. Wrong. • D. quick-witted: This means mentally sharp. It is not the direct opposite of being vulnerable. Wrong.

Answer: B. invincible

Tip: In "opposite in meaning" questions, the synonym is almost always among the options as a trap. Here, "vulnerable" is the same as "sitting duck," so eliminate it immediately. Always translate the idiom into plain meaning first, then look for the word that points the other way.
