Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- A city tested two road surfaces on similar streets.
- Surface P needed repair after 4 years.
- Surface Q needed repair after 9 years.
- Surface Q cost 30% more to lay.
The student wants to compare how long the two surfaces lasted. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. Surface Q lasted 9 years before needing repair, more than twice the 4 years of Surface P.Correct
- B. Surface Q cost 30% more to lay.
- C. The city tested two road surfaces.
- D. Surface P needed repair after 4 years.
Answer: A. Surface Q lasted 9 years before needing repair, more than twice the 4 years of Surface P.

- B. Surface Q cost 30% more to lay.
- Cost, not lifetime.
- C. The city tested two road surfaces.
- The setup, no result.
- D. Surface P needed repair after 4 years.
- One figure can't compare.
