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 FOURTH sentence after rearrangement?

The correct option is A.

To determine the correct sequence of sentences for a coherent paragraph, let us analyze the thematic connections between the given statements:

1. Sentence D introduces the central topic of the paragraph: "The Arctic region is witnessing an alarming rate of glacier melting due to rising global temperatures." This serves as the opening statement.

2. Sentence C logically follows D by explaining the cause behind this phenomenon: "Scientists attribute this rapid ice loss to global climate change, which has intensified over the past few decades."

3. Sentence F provides specific research details regarding the rate of warming: "Some recent research highlights that the Arctic is warming at least twice as fast as the global average."

4. Sentence A directly elaborates on the phenomenon mentioned in F, defining it as Arctic amplification: "This accelerated warming, known as Arctic amplification, has drawn significant concern among climate experts." Therefore, sentence A is the FOURTH sentence in the sequence.

5. Sentence E explains the broader consequences of this melting: "The melting of these glaciers not only raises sea levels but also disrupts marine ecosystems and weather patterns worldwide."

6. Sentence B adds further findings and projections for the future: "Studies further reveal that if current trends continue, the Arctic could experience ice-free summers within this century."

7. Sentence G concludes the paragraph with a call to action based on the preceding arguments: "Therefore, global efforts to reduce greenhouse gas emissions are critical to slow down these changes and protect fragile ecosystems."

The complete and logical order of the sentences is D - C - F - A - E - B - G.

Since sentence A is in the 4th position, option A is the correct answer.
