Para-jumble (materials shift): Reorder the sentences to explain why polymers are replacing metals, from definition and advances to applications and economics. 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." Between S1 and S6, put the ideas in a clear technical flow: 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." Choose the correct sequence of P–Q–R–S that completes the paragraph.

Answer
Correct Answer: QRSP
Explanation
Given data
- Q defines polymers structurally.
- R notes that metal-like strength has been achieved.
- S gives an application (car bumpers).
- P cites cost/processing advantages explaining adoption.
Concept / ApproachExplain the what (Q), then the capability (R), then a real-world example (S), and finally the economic rationale (P). This sequence supports S1's claim and leads to S6's note about academic programmes.
Step-by-stepS1 + Q → introduce and define.… + R → establish parity with metals.… + S → show visible replacement in automobiles.… + P → why industry prefers polymers (cost & processing).
