The concept of 'digital twin' has gained significant traction in engineering and urban planning. A digital twin is a virtual replica of a physical system, continuously updated with real-time data from sensors. This dynamic model allows engineers to simulate scenarios, predict failures, and optimize performance without disrupting the actual infrastructure. In smart cities, digital twins of entire districts can monitor traffic flow, energy consumption, and environmental conditions, enabling proactive management. However, critics argue that the reliance on vast data sets raises privacy concerns and that the complexity of these models may lead to over-reliance, potentially overlooking unforeseen variables not captured in the simulation.

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
