[amp_mcq option1=”PQRS” option2=”PQSR” option3=”QRSP” option4=”QSPR” correct=”option1″]

The correct answer is: A. PQRS

The first sentence (S1) introduces the topic of the paragraph, which is the use of plastic containers. The second sentence (P) states that most people think that using plastic containers is the right thing to do, as it is economical. The third sentence (Q) provides evidence to support this claim, by stating that plastic containers are cheap and light. The fourth sentence (R) provides further evidence to support this claim, by stating that it is easier to transport materials packaged in plastic containers than in glass bottles. The fifth sentence (S) provides a contrast to the previous sentences, by stating that plastic containers are a big threat to the environment. The sixth sentence (S6) concludes the paragraph by summarizing the main points.

The other options are incorrect because they do not follow the logical order of the sentences. Option B (PQSR) puts the sentence that provides evidence to support the claim (Q) before the sentence that states the claim (P). Option C (QRSP) puts the sentence that provides a contrast to the previous sentences (S) before the sentence that introduces the topic of the paragraph (S1). Option D (QSPR) puts the sentence that concludes the paragraph (S6) before the sentence that provides evidence to support the claim (Q).
