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?

To determine the correct sequence of sentences, let us analyze the logical flow and connections between the given statements:

1. Sentence D introduces the central topic of the passage: the alarming rate of glacier melting in the Arctic region due to rising global temperatures. This serves as an ideal introductory sentence that sets the context for the entire text.
2. Sentence C follows by explaining the cause identified by scientists for this rapid ice loss (global climate change).
3. Sentence F introduces recent research supporting the severity of climate change in the region, stating that the Arctic is warming at least twice as fast as the global average.
4. Sentence A connects directly to Sentence F by labeling this phenomenon as "Arctic amplification" and noting the concern of climate experts.
5. Sentence B builds on the findings, indicating that if current trends persist, the Arctic could see ice-free summers within this century.
6. Sentence E elaborates on the broader consequences of melting glaciers (rising sea levels, disruption of marine ecosystems, and weather patterns).
7. Sentence G provides a concluding logical statement starting with "Therefore," emphasizing the need for global efforts to reduce emissions.

Thus, the logical order of the paragraph is D - C - F - A - B - E - G.

The FIRST sentence after rearrangement is D.

Therefore, the correct answer option is D.
