Rearrange the following sentences and answer the given questions.

A. This accelerated warming, known as Arctic amplification, has drawn significant concern among climate experts.

B. Studies further reveal that if current trends continue, the Arctic could experience ice-free summers within this century.

C. Scientists attribute this rapid ice loss to global climate change, which has intensified over the past few decades.

D. The Arctic region is witnessing an alarming rate of glacier melting due to rising global temperatures.

E. The melting of these glaciers not only raises sea levels but also disrupts marine ecosystems and weather patterns worldwide.

F. Some recent research highlights that the Arctic is warming at least twice as fast as the global average.

G. Therefore, global efforts to reduce greenhouse gas emissions are critical to slow down these changes and protect fragile ecosystems.

Which of the following is the FIRST sentence after rearrangement?

Correct Answer: The first sentence after rearrangement is D.

To determine the correct logical sequence of the given sentences, let us analyze each sentence and how they connect to one another:

1. Sentence D: "The Arctic region is witnessing an alarming rate of glacier melting due to rising global temperatures."
This sentence serves as the ideal introductory sentence (topic sentence) because it broadly introduces the primary subject of discussion—the Arctic region, rising global temperatures, and the alarming rate of glacier melting.

2. Sentence C: "Scientists attribute this rapid ice loss to global climate change, which has intensified over the past few decades."
This sentence follows sentence D directly, as "this rapid ice loss" clearly refers back to the "alarming rate of glacier melting" mentioned in sentence D.

3. Sentence F: "Some recent research highlights that the Arctic is warming at least twice as fast as the global average."
This sentence adds further scientific context and evidence regarding the intensity of the warming mentioned in sentence C.

4. Sentence A: "This accelerated warming, known as Arctic amplification, has drawn significant concern among climate experts."
Sentence A refers directly to "this accelerated warming" (the warming at least twice as fast as the global average described in F) and introduces the term "Arctic amplification".

5. Sentence E: "The melting of these glaciers not only raises sea levels but also disrupts marine ecosystems and weather patterns worldwide."
This sentence discusses the consequences and global impacts of the glacier melting and warming detailed in the preceding sentences.

6. Sentence B: "Studies further reveal that if current trends continue, the Arctic could experience ice-free summers within this century."
This sentence provides additional research findings regarding future projections if the current trends persist.

7. Sentence G: "Therefore, global efforts to reduce greenhouse gas emissions are critical to slow down these changes and protect fragile ecosystems."
The word "Therefore" marks this as the logical concluding statement, summarizing the necessary action based on the points raised.

Logical Order: D - C - F - A - E - B - G

Thus, the FIRST sentence in the rearranged paragraph is sentence D.
