Explanation
Correct Answer
2-4-3-1
Explanation
Chronological and Logical Ordering To arrange these sentences into a coherent paragraph, the narrative must establish a core concept, explain its root causes, describe its physical impacts, and conclude with a logical solution.
Step 1 The sequence begins with sentence 2, "Global warming is a serious threat to our planet." This introduces the central topic and sets the premise for the entire paragraph.
Step 2 This is followed by sentence 4, "Human activities like deforestation and burning fossil fuels contribute to it." The pronoun "it" at the end of this sentence directly links back to the singular noun phrase "Global warming" established in sentence 2, identifying its primary causes.
Step 3 Next is sentence 3, "Rising temperatures cause melting glaciers and extreme weather conditions." This expands upon the theme by illustrating the direct physical consequences and symptoms of the global warming trend introduced earlier.
Step 4 The paragraph concludes with sentence 1, "Therefore, it is important to take measures to reduce carbon emissions." The transitional word "Therefore" signals a definitive concluding statement or call to action, offering a resolution to the problem detailed through the previous three statements.
Thus, the logical and structural flow of the ideas is seamlessly maintained in the sequence 2-4-3-1.
Key Points
Correct Sequence 2-4-3-1 (Core problem - Human causes - Environmental effects - Concluding solution).
Grammatical Role Paragraph jumble / Sentence alignment (tests structural cohesion, logical pronoun-antecedent relationships, and cause-and-effect transitions).
