The concept of 'digital twins' has evolved from a niche engineering tool into a cornerstone of modern infrastructure management. A digital twin is a virtual replica of a physical asset, system, or process, continuously updated with real-time data from sensors and IoT devices. This dynamic model allows engineers and urban planners to simulate scenarios, predict failures, and optimize performance without disrupting real-world operations. For instance, in smart city initiatives, digital twins of transportation networks can model traffic flow under various conditions, enabling proactive adjustments that reduce congestion and emissions. However, the reliance on massive data streams raises concerns about cybersecurity and data privacy. Moreover, the accuracy of a digital twin is only as good as the data feeding it; incomplete or biased data can lead to flawed simulations, undermining the very benefits it promises. Thus, while digital twins offer unprecedented opportunities for efficiency, they also demand robust governance frameworks to ensure reliability and ethical use.

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
