Solution: To form a meaningful sentence, we need to rearrange the parts in a logical sequence. Let's break it down step-by-step based on the given parts:
- S: metal
- R: like most other materials
- Q: expands
- P: when heated
Now, let's arrange them:
- The subject of the sentence is provided by part S: "metal".
- Part R qualifies the subject by comparing it to other materials: "like most other materials".
- Part Q describes the action: "expands".
- Part P explains the condition under which the action occurs: "when heated".
Putting it all together, the sentence becomes: "Metal, like most other materials, expands when heated." This matches the provided correct order: S-R-Q-P.
