Exam-style question
Try this first
For Bulk properties of solids, which option best supports this approved objective using a clear unit focus: Distinguish elastic deformation from plastic deformation?.
- A.Distinguish elastic deformation from plastic deformation. This answer stays within Bulk properties of solids and uses the correct unit focus.
- B.A vague response that names the topic but does not apply the A-Level Physics reasoning.
- C.A neighbouring-topic response that belongs outside Bulk properties of solids.
- D.A response that confuses the quantity, unit, graph feature, evidence, or conclusion required here.
Model answer
What a good answer should say
- The correct option is Distinguish elastic deformation from plastic deformation.
- This answer stays within Bulk properties of solids and uses the correct unit focus.
Explanation
Why this works
This answer stays within Bulk properties of solids and uses the correct unit focus." because it directly supports the approved learning objective: Distinguish elastic deformation from plastic deformation. The other options are weaker because they are vague, use the wrong context, or confuse a nearby A-Level Physics quantity, unit, graph feature, evidence point, or conclusion in Mechanics and materials.
