Rearrange the following sentences to form a coherent paragraph:

1. This is particularly challenging in industries such as steel and cement production, where emissions are an integral part of the manufacturing process. 2. As a result, carbon capture and storage (CCS) technologies have emerged as a crucial component of strategies aimed at reducing industrial greenhouse gas emissions. 3. Achieving carbon neutrality requires a significant reduction in emissions across all economic sectors. 4. These technologies capture carbon dioxide at the source, preventing its release into the atmosphere and either utilizing it or storing it permanently underground.

A1, 2, 3, 4

B3, 1, 2, 4

C2, 1, 3, 4

D4, 3, 1, 2

Answer:

B. 3, 1, 2, 4

Read Explanation:

To arrange sentences into a coherent paragraph, you need to identify the introductory topic sentence, notice transition words, and trace logical connections (like pronouns and specific terminology) between ideas.

  1. Find the Opening Sentence: Sentence 3 acts as the perfect anchor for the paragraph. It introduces the broad, overarching theme: the universal goal of "Achieving carbon neutrality" across all economic sectors.

  2. Establish the Challenge: Sentence 1 begins with "This is particularly challenging..." The pronoun "This" directly references the goal mentioned in Sentence 3 (reducing emissions across all sectors). It narrows the focus from "all sectors" to specific tough industries like steel and cement.

  3. Introduce the Solution: Sentence 2 acts as a logical bridge starting with the transition phrase "As a result..." Because those specific industries struggle to reduce emissions naturally, Carbon Capture and Storage (CCS) technologies have emerged as a necessary strategy.

  4. Detail the Mechanism: Sentence 4 begins with "These technologies...", which directly refers back to the plural noun "CCS technologies" introduced at the end of Sentence 2. It explains exactly how those technologies work.

Therefore, the logical and grammatical flow of the paragraph is 3 $\rightarrow$ 1 $\rightarrow$ 2 $\rightarrow$ 4.
