Analyze the question: This tests your knowledge of idioms. The idiom is "a good head on one's shoulders."

Explain the concept: The idiom "to have a good head on your shoulders" means a person is sensible, practical, and able to make sound judgments. It is not about physical looks, speed of thinking, or behaviour alone. It is about having good common sense and wisdom.

Work through the options:

• A. thinks fast: This is about speed of thought. The idiom is about sound judgment, not speed. ✗
• B. is sensible: This matches the idiom's meaning of being level-headed and having good judgment. ✓
• C. is very beautiful: This is about physical appearance and has nothing to do with the idiom. ✗
• D. is well behaved and diligent: This is close in context, since such a child may do well in school. But the idiom does not directly mean good behaviour or hard work. It means good sense. ✗

Answer: The sentence says the daughter will do well in school because she is sensible and has sound judgment.

Exam tip: For idiom questions, don't translate word by word ("head" and "shoulders" have nothing to do with the meaning). Think of the whole phrase. Also remember similar idioms: "level-headed" means calm and sensible, and "head in the clouds" means unrealistic.
