Question

In the questions below, the passage consist of six sentences. The first and the sixth sentences are given. (S1, S6) The middle four sentences in each have been removed and jumbled up. These are labeled as P, Q, R and S. Find out 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 a long chains of hydrocarbons 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.
The proper sequence should be:

• A. QRSP
• B. RSQP
• C. RQSP
• D. QRPS

Answer 1

The Correct Option is D

To identify the correct sequence of the jumbled sentences between S1 and S6, we need to logically connect the ideas through their relationships and transitions:

• Reading S1, we know the topic is about polymers replacing metals.
• Sentence Q introduces polymers, describing them as long chains of hydrocarbons, which logically follows S1 by explaining what polymers are.
• Sentence R states that polymers as strong as metals have been developed, building upon Q by linking the definition of polymers to their strength compared to metals.
• Then, Sentence P lists the advantages of polymers, asserting that they are cheaper and easier to process, making them viable alternatives to metals. This follows naturally from R as it discusses practical benefits.
• Finally, Sentence S gives a specific example of polymers replacing metals, in the context of car bumpers, providing a real-world application to solidify the argument of sentence P.

Considering this analysis, the correct sequence is QRPS. This flows logically from introducing polymers and their characteristics (Q), to describing their developed strength (R), followed by their advantages (P), and concluding with a specific example of their application replacing metals (S). This sequence is correctly followed by S6 which states that special programs focus on polymer science, adding to the relevance of the topic.
