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.
Two columns are given below. Column I contains two words, while Column II lists several words/phrases. Select the option that correctly pairs each word in Column I with its appropriate replacement(s) from Column II.
| Column I | Column II |
|---|---|
| P . accelerated | 1. easily broken |
| Q. fragile | 2. quickened |
| 3. strengthened | |
| 4. delicate |
Correct Answer :
P–2 and Q–4
Solution :
The correct answer is P–2 and Q–4.
To determine the correct pairings between Column I and Column II, let us analyze the context and meanings of the words in Column I:
1. Word P: "accelerated"
In sentence A, "accelerated" refers to warming that has sped up or increased in rate. Looking at Column II:
• "quickened" (2) means made faster or accelerated.
• "strengthened" (3) means made stronger, which does not accurately replace "accelerated" in terms of speed or rate.
Therefore, P pairs with 2 (quickened).
2. Word Q: "fragile"
In sentence G, "fragile" refers to ecosystems that are delicate, easily harmed, or vulnerable. Looking at Column II:
• "easily broken" (1) usually refers to physical objects that break easily, whereas "delicate" (4) perfectly captures the nature of fragile ecosystems.
• "delicate" (4) is the most appropriate replacement for "fragile" in this context.
Therefore, Q pairs with 4 (delicate).
Thus, the correct combination matching each word in Column I with its appropriate replacement from Column II is P–2 and Q–4.
