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 SIXTH sentence after rearrangement?

The correct answer is B.

To find the correct sequence of sentences, let us analyze the logical connection and flow of ideas among the given statements:

1. First sentence (D): Statement D introduces the central topic—the alarming rate of glacier melting in the Arctic region caused by rising global temperatures ("The Arctic region is witnessing an alarming rate of glacier melting due to rising global temperatures.").

2. Second sentence (C): Statement C directly explains the cause of this rapid ice loss ("Scientists attribute this rapid ice loss to global climate change...").

3. Third sentence (F): Statement F provides specific evidence of the warming trend ("Some recent research highlights that the Arctic is warming at least twice as fast as the global average.").

4. Fourth sentence (A): Statement A refers to the phenomenon described in sentence F ("This accelerated warming, known as Arctic amplification...").

5. Fifth sentence (E): Statement E elaborates on the broader consequences of the melting glaciers mentioned earlier ("The melting of these glaciers not only raises sea levels but also disrupts marine ecosystems...").

6. Sixth sentence (B): Statement B builds upon the impacts mentioned in E by adding further research predictions ("Studies further reveal that if current trends continue, the Arctic could experience ice-free summers within this century.").

7. Seventh/Final sentence (G): Statement G provides the logical conclusion starting with "Therefore" ("Therefore, global efforts to reduce greenhouse gas emissions are critical...").

The complete and coherent paragraph order is D - C - F - A - E - B - G.

Therefore, the SIXTH sentence after rearrangement is sentence B.
