The concept of 'digital twin' has gained significant traction in industrial engineering, referring to a virtual replica of a physical system that is continuously updated with real-time data. This technology enables predictive maintenance by simulating potential failures before they occur, thereby reducing downtime and operational costs. However, its implementation is not without challenges. The reliance on vast amounts of sensor data raises concerns about data security and privacy, while the complexity of integrating digital twins into existing legacy systems often requires substantial investment and specialized expertise. Furthermore, scholars argue that the accuracy of a digital twin is inherently limited by the quality of its underlying model, which may not capture all variables in dynamic environments. Despite these limitations, proponents contend that as artificial intelligence and IoT technologies advance, digital twins will become indispensable for optimizing complex infrastructures, from manufacturing plants to urban transportation networks. Thus, while the path to widespread adoption is fraught with obstacles, the potential benefits in efficiency and resilience make it a compelling area of continued research and development.

IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
Manage time: about 20 minutes per passage; skip difficult questions first
