Question

Rearrange the following sentences to form a coherent paragraph:

1. The most prevalent of these is the peer-to-peer (P2P) network, where no single entity controls the entire system. 2. Blockchain technology, at its core, is a distributed ledger that maintains a decentralized record of transactions. 3. This decentralized structure ensures security and transparency by requiring network consensus for any new record to be added. 4. It functions by distributing copies of the ledger across a vast network of computers.

• A. 2, 4, 1, 3
• B. 4, 1, 3, 2
• C. 1, 4, 2, 3
• D. 2, 1, 4, 3

Answer 1

Answer:

A. 2, 4, 1, 3

(2) Blockchain technology, at its core, is a distributed ledger that maintains a decentralized record of transactions. (4) It functions by distributing copies of the ledger across a vast network of computers. (1) The most prevalent of these is the peer-to-peer (P2P) network, where no single entity controls the entire system. (3) This decentralized structure ensures security and transparency by requiring network consensus for any new record to be added.

To determine the correct chronological and logical sequence, we can track the pronouns and structural links between the sentences:

• Finding the Opening Sentence (Sentence 2):

  Sentence 2 is the ideal opening statement. It is completely independent and introduces the core theme of the paragraph—"Blockchain technology"—by giving its foundational definition ("a distributed ledger").

• Establishing the First Link (Sentence 2 $\rightarrow$ Sentence 4):

  Sentence 4 begins with the pronoun "It" ("It functions by..."). This pronoun directly refers back to the singular noun phrase "Blockchain technology" established in Sentence 2. Furthermore, Sentence 4 expands on how that distributed ledger actually works by explaining that it distributes copies across a network.

• Establishing the Second Link (Sentence 4 $\rightarrow$ Sentence 1):

  Sentence 4 introduces the concept of a "vast network of computers". Sentence 1 immediately follows up on this by stating, "The most prevalent of these is the peer-to-peer (P2P) network...". The demonstrative phrase "these" directly qualifies and categorizes the types of networks mentioned in Sentence 4.

• Finding the Concluding Sentence (Sentence 3):

  Sentence 3 starts with the summary phrase, "This decentralized structure...". This refers back to the description of the P2P network in Sentence 1 where "no single entity controls the entire system". Sentence 3 logically concludes the paragraph by explaining the ultimate benefits (security, transparency, and consensus) derived from the entire structure built by the previous sentences.
