Show answer & explanation
Correct answer: A
Explanation
The correct logical sequence for the passage is RSPQ.
Logical Sequence:
Sentence 1: "Oceans cover more than 70% of Earth's surface." (Introduces the general subject: Oceans).
Part R: "Oceans regulate global temperature and climate." (This logically follows Sentence 1 by providing a broad, fundamental function of the vast area just mentioned).
Part S: "They provide food and employment to millions." (The pronoun "They" refers back to the "Oceans" mentioned in 1 and R, expanding on their benefits to humans).
Part P: "Marine species are crucial for food chains." (Links to the mention of "food" in Part S, shifting focus to the biological importance of marine life).
Part Q: "But plastic waste threatens marine life." (Introduces a conflict or problem using the contrastive conjunction "But," specifically referencing the "marine life" introduced in Part P).
Sentence 6: "Ocean conservation must be prioritized." (Provides a logical conclusion/solution to the problem of plastic waste raised in Part Q).
