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 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. The Proper sequence should be: A. QRSP B. RSQP C. RQSP D. QRPS

[amp_mcq option1=”QRSP” option2=”RSQP” option3=”RQSP” option4=”QRPS” correct=”option4″]

The correct answer is: D. QRPS

The first sentence, “Metals are today being replaced by polymers in many applications,” introduces the topic of the passage, which is the replacement of metals by polymers. The second sentence, “Polymers are essentially a long chains of hydrocarbon molecules,” provides more information about polymers. The third sentence, “Today polymers as strong as metals have been developed,” supports the claim that polymers are a viable alternative to metals. The fourth sentence, “These have replaced the traditional chromium-plated metallic bumpers in cars,” provides an example of how polymers are being used to replace metals. The fifth sentence, “Many Indian Institutes of science and Technology run special programmes on polymer science,” provides additional information about polymers, but it is not relevant to the main point of the passage, which is the replacement of metals by polymers. Therefore, the correct sequence of the sentences is QRPS.

Here is a more detailed explanation of each sentence:

  • Sentence 1: “Metals are today being replaced by polymers in many applications.” This sentence introduces the topic of the passage, which is the replacement of metals by polymers.
  • Sentence 2: “Polymers are essentially a long chains of hydrocarbon molecules.” This sentence provides more information about polymers.
  • Sentence 3: “Today polymers as strong as metals have been developed.” This sentence supports the claim that polymers are a viable alternative to metals.
  • Sentence 4: “These have replaced the traditional chromium-plated metallic bumpers in cars.” This sentence provides an example of how polymers are being used to replace metals.
  • Sentence 5: “Many Indian Institutes of science and Technology run special programmes on polymer science.” This sentence provides additional information about polymers, but it is not relevant to the main point of the passage, which is the replacement of metals by polymers.
