Rearrange the following sentences to form a meaningful passage:
1. Marine ecosystems are sensitive to temperature shifts.
2. Coral bleaching is one visible consequence.
3. Rising ocean temperatures disrupt symbiotic algae.
4. This affects reef biodiversity and fisheries.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1-3-2-4.
Logical flow:
1: This introduces the topic that marine ecosystems are sensitive to temperature changes.
3: This explains the effect of rising ocean temperatures on symbiotic algae.
2: This follows naturally because coral bleaching is a visible consequence of the disruption mentioned earlier.
4: This concludes the passage by describing the broader impact on reef biodiversity and fisheries.
Thus, the correct sequence becomes: 1 → 3 → 2 → 4
Final Passage: Marine ecosystems are sensitive to temperature shifts. Rising ocean temperatures disrupt symbiotic algae. Coral bleaching is one visible consequence. This affects reef biodiversity and fisheries.
Hence, the chosen option is correct.
