The concept of 'digital twins' has gained significant traction in industrial engineering, referring to virtual replicas of physical systems that are continuously updated with real-time data. These models enable predictive maintenance, allowing engineers to simulate potential failures before they occur, thereby reducing downtime and operational costs. However, the efficacy of digital twins hinges on the quality and granularity of the data collected, as well as the sophistication of the algorithms used to process it. Moreover, ethical concerns arise regarding data privacy and the potential for over-reliance on automated decision-making, which may undermine human expertise. As industries increasingly adopt this technology, a balanced approach is necessary to harness its benefits while mitigating risks.

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
