In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
Rainforests are essential for biodiversity. P: Trees store carbon and release oxygen. Q: They are home to countless species. R: Yet, deforestation threatens these ecosystems. S: Some plants even hold potential medical cures. 6. So, preserving rainforests is a global concern.
Show answer & explanation
Correct answer: A
Explanation
The most logical order of the parts for this sentence rearrangement question is QPSR.
Logical Sequence:
Sentence 1: "Rainforests are essential for biodiversity." (Introduces the topic and the theme of biodiversity).
Part Q: "They are home to countless species." (Follows sentence 1 directly by explaining why they are essential for biodiversity).
Part P: "Trees store carbon and release oxygen." (Provides another positive reason why rainforests are important, continuing the list of benefits).
Part S: "Some plants even hold potential medical cures." (Adds a final supporting detail about the value of rainforest plants; the word "even" indicates this is an addition to the previous points).
Part R: "Yet, deforestation threatens these ecosystems." (Uses the transition "Yet" to contrast the benefits mentioned in P, Q, and S with the current threat).
Sentence 6: "So, preserving rainforests is a global concern." (Concluding statement that logically follows the threat mentioned in part R).
