This means that the speaker wishes the listener …

Analyze the question: "More power to your elbow" is an idiom. You are not meant to read it literally, because it has nothing to do with the elbow itself. The question asks what the speaker wishes the listener.

Explain the concept: The idiom "more power to your elbow" is an expression of encouragement or congratulation. It means "may you keep up your energy, strength, and success in what you are doing." It is similar to saying "well done, keep it up!" or "may your strength and effort increase."

Step-by-step solution:

1. A. a higher position: The idiom has nothing to do with rank or promotion. ❌
2. B. good health: This would match "I wish you good health," a different expression. ❌
3. C. greater attempts: This does not match the meaning. The idiom does not ask someone to try more times. ❌
4. D. more muscles: This is the literal reading, which is the trap. The idiom is figurative. ❌
5. E. more strength: This matches the idiom's meaning of wishing someone more strength, energy, and success in their work. ✅

The idiom originally referred to the strength of the elbow, as in lifting a drinking glass or working with the arm. It came to mean "may your strength and ability increase."

Answer: E. more strength

Exam tip: When an English question gives an idiom in quotation marks, avoid the option that reads it literally (here, "more muscles"). Idioms almost always have a figurative meaning. Look for the option that captures the general sense, here encouragement and strength.
