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 SECOND sentence after rearrangement?

To determine the correct second sentence after rearrangement, let us analyze the logical flow and connections among all seven sentences (A through G):

1. Identify the Opening/First Sentence:
Sentence D ("The Arctic region is witnessing an alarming rate of glacier melting due to rising global temperatures.") introduces the main topic of the passage—the Arctic region, glacier melting, and rising global temperatures. It serves as an ideal introductory statement.

2. Identify the Second Sentence:
Sentence C ("Scientists attribute this rapid ice loss to global climate change, which has intensified over the past few decades.") directly builds upon Sentence D by explaining the cause of "this rapid ice loss" (referring back to the glacier melting mentioned in D). Therefore, C is the second sentence in the sequence.

3. Trace the Subsequent Flow:
- F ("Some recent research highlights that the Arctic is warming at least twice as fast as the global average.") introduces specific research details about Arctic warming.
- A ("This accelerated warming, known as Arctic amplification, has drawn significant concern among climate experts.") connects to F by defining "This accelerated warming" as Arctic amplification.
- E ("The melting of these glaciers not only raises sea levels but also disrupts marine ecosystems and weather patterns worldwide.") discusses the broad impacts of the melting.
- B ("Studies further reveal that if current trends continue, the Arctic could experience ice-free summers within this century.") provides further study predictions.
- G ("Therefore, global efforts to reduce greenhouse gas emissions are critical to slow down these changes and protect fragile ecosystems.") provides a conclusion starting with "Therefore".

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

The correct option corresponding to the SECOND sentence after rearrangement is C.

The correct answer is Option C.
