Question

S1: Metals are today being replaced by polymers in many applications.  S6: Many Indian Institutes of science and Technology run special programmes on polymer science.
P: Above all, they are cheaper and easier to process making them a viable alternative to metals.
Q: Polymers are essentially long chains of hydrocarbon molecules.
R: Today polymers as strong as metals have been developed.
S: These have replaced the traditional chromium-plated metallic bumpers in cars.
Proper sequence:

Accepted Answer

A. QRSP

1. S1 says metals are being replaced by polymers; first explain WHAT polymers are.
2. Q defines polymers; R says strong polymers exist; S gives the bumpers example; P clinches with cheaper + easier to process.
3. Sequence QRSP flows from definition to strength to example to overall reason, ending naturally at S6.
