Practice Reading Passage: Blockchain and Supply Chain Management (Medium Text)

Blockchain: Revolutionizing Supply Chain Management

Blockchain technology, initially conceptualized for digital currencies, has transcended its origins to revolutionize various sectors, notably supply chain management. By ensuring enhanced transparency, security, and efficiency, blockchain is set to redefine how businesses manage their supply chains.

Enhanced Transparency
Blockchain’s decentralized and immutable ledger provides an unparalleled level of transparency. Each stakeholder in the supply chain network can access real-time data about the movement and status of goods. This access ensures that information cannot be altered retroactively, reducing the risk of fraud and errors. For instance, a retailer can verify the origin and journey of a product from the manufacturer to their store, leading to improved trust among consumers.

Increased Security
Security is a paramount concern in supply chain management, where data breaches can have significant repercussions. Blockchain technology addresses this issue by encrypting data and controlling access through consensus mechanisms. Only authorized participants can validate transactions, ensuring data integrity and safeguarding intellectual property.

Operational Efficiency
Traditional supply chains often suffer from inefficiencies due to a lack of standardized protocols and communication issues among various stakeholders. Blockchain integrates smart contracts—self-executing contracts with the terms of the agreement directly written into code. These contracts automate processes, reduce the need for intermediaries, and expedite transactions. For example, a shipment’s delivery confirmation on the blockchain could automatically trigger an invoice, streamlining financial operations.

Common Mistakes

• Overlooking Keywords: During the exam, students often overlook keywords in the question and passage, leading to incorrect answers. Always highlight or underline key terms.
• Misunderstanding the Passage: It’s crucial to grasp the main idea of each paragraph. Summarize each section in your own words if necessary.
• Rushing Through Questions: Allocate your time wisely. Thoroughly read the passage before attempting the questions to ensure better comprehension.

Vocabulary

• Decentralized (adj.): /ˌdiːˈsɛntrəlaɪzd/ – the transfer of authority from central to local government or to a smaller unit.
• Immutable (adj.): /ɪˈmjuːtəbl̩/ – unchanging over time or unable to be changed.
• Consensus (n.): /kənˈsɛnsəs/ – general agreement among a group of people.

Grammar Points

• Passive Voice: “Blockchain technology addresses this issue by encrypting data and controlling access through consensus mechanisms.”

  • Structure: be + past participle. This highlights the action and the recipient rather than who performs the action.

• Relative Clauses: “Traditional supply chains, which often suffer from inefficiencies, benefit significantly from blockchain.”

  • Structure: “which” is used to add extra information about the subject, without starting a new sentence.

Tips for High Reading Scores in IELTS

• Practice Regularly: Consistent practice with various passages will improve comprehension and speed.
• Enhance Vocabulary: Build a strong vocabulary base, focusing on academic and technical terms.
• Develop Skimming and Scanning Skills: Quickly identify main ideas and specific information.
