Rearrange the following sentences in the correct order to make a logical passage: 1. This immutability makes blockchain particularly suited for financial transactions and supply chain verification. 2. Blockchain is a distributed ledger technology that records data across a network of computers in linked blocks. 3. Each block contains a cryptographic hash of the preceding block, rendering unauthorised alteration extremely difficult. 4. Enterprises across sectors are actively piloting blockchain solutions to enhance transparency and reduce fraud.

1. 2 - 1 - 3 - 4
2. 2 - 4 - 1 - 3
3. 3 - 4 - 2 - 1
4. 2 - 3 - 1 - 4

Correct answer: 2 - 3 - 1 - 4

Solution

Sentence 2 introduces blockchain. Sentence 3 explains the mechanism that makes it hard to alter, which leads naturally to sentence 1 about immutability and suitability. Sentence 4 is a concluding application statement, so the correct order is 2-3-1-4.
