Instructions: The passage below consists of six sentences. The first and the sixth sentences are given (S1, S6). The middle four sentences have been removed and jumbled up, labelled P, Q, R and S. Find the proper order for the four sentences.

S1: Metals are today being replaced by polymers in many applications.
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.
S6: Many Indian Institutes of Science and Technology run special programmes on polymer science.

Question

Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.

Answer 1

Tracking a repeated key phrase across the sentences is often the fastest way to solve these jumbles, and here the phrase “alternative to metals” links two sentences directly.

S1 opens by saying metals are being replaced by polymers, so the next sentence should explain what a polymer actually is: that is Q.
After defining polymers, the passage should explain why they can replace metals; R (strength) and P (cost and ease of processing) are both reasons, with P's ending phrase “viable alternative to metals” echoing and concluding the point R started, so R must come before P.
S (“these have replaced the traditional... bumpers”) needs an antecedent for “these”, and the only earlier sentence discussing why polymers replace metal parts is P, so S follows P as its concrete example.
Reading in full: “Metals are being replaced by polymers (S1). Polymers are chains of hydrocarbons (Q). Today, polymers as strong as metals exist (R). Above all, they are cheaper and easier to process, a viable alternative to metals (P). These have replaced chromium bumpers in cars (S). Institutes run polymer science programmes (S6).” This flows logically start to finish.

So the correct answer is option D, QRPS.
