Rearrange the following sentences to form a coherent paragraph:
1. Anthropogenic climate change, driven by the emission of greenhouse gases, is causing a wide range of discruptions to global ecosystems.
2. Glacial retreat and the melting of polar ice caps have accelerated, contributing to a rise in global sea levels.
3. This has led to more frequent and intense extreme weather events, including droughts, floods, and heatwaves.
4. The collective impact of these changes poses a serious threat to human societies and biodiversity.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1, 3, 2, 4.
Logical Sequence:
-
Sentence 1 (The Introduction): This sentence introduces the primary subject: Anthropogenic climate change. It defines the cause (greenhouse gases) and the general effect (disruptions to ecosystems), serving as the perfect opening statement.
-
Sentence 3 (The Immediate Consequence): The phrase 'This has led to' directly refers back to the 'climate change' and 'disruptions' mentioned in Sentence 1. It provides specific examples of atmospheric disruptions like extreme weather events (droughts, floods).
-
Sentence 2 (The Secondary Consequence): This sentence moves from atmospheric events to geological ones (glacial retreat and sea-level rise). It follows the pattern of listing the various 'disruptions' introduced in the first sentence.
-
Sentence 4 (The Conclusion/Impact): The phrase 'The collective impact of these changes' summarizes all the points mentioned in sentences 1, 3, and 2. It concludes the paragraph by highlighting the overall threat to humanity and biodiversity.
Correct Paragraph: Anthropogenic climate change, driven by the emission of greenhouse gases, is causing a wide range of disruptions to global ecosystems. This has led to more frequent and intense extreme weather events, including droughts, floods, and heatwaves. Glacial retreat and the melting of polar ice caps have accelerated, contributing to a rise in global sea levels. The collective impact of these changes poses a serious threat to human societies and biodiversity.
Hence, the chosen option is correct.
