The concept of 'digital twins' has evolved from its industrial origins to become a pivotal tool in environmental conservation. A digital twin is a virtual replica of a physical system, continuously updated with real-time data. In ecology, researchers create digital twins of ecosystems, such as forests or coral reefs, to simulate the impacts of climate change, pollution, or conservation interventions. This allows for predictive modeling without disturbing the actual environment. However, critics argue that the complexity of natural systems often exceeds the computational capacity of current models, leading to oversimplified predictions. Despite these limitations, proponents suggest that digital twins offer a cost-effective means to test hypotheses and guide policy decisions, especially in remote or sensitive areas where physical experiments are impractical. The success of such tools hinges on the quality of data and the interdisciplinary collaboration between ecologists and data scientists.

C. C. They are cheaper than any other form of scientific research.
D. D. They eliminate the need for real-time data collection.
✅ 正确答案
B. They allow testing of scenarios without causing harm to real ecosystems.
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)
