Five sentences (labelled 1 to 5), are given below. Identify the sentence that does not belong to the common topic.
- Sustainable urban development increasingly emphasises compact city designs that integrate renewable energy systems and efficient public transportation.
- Circular economy frameworks encourage industries to design products with longer lifecycles, reducing waste and resource extraction.
- Large-scale coral bleaching has disrupted oceanic ecosystems, highlighting the vulnerability of marine biodiversity to rising global temperatures.
- Technological innovation in waste-management systems is emerging as a cornerstone of eco-conscious city planning and governance.
- Governments across the world are implementing green infrastructure policies to balance economic expansion with environmental residence.

Solution
The question is testing for topic coherence and identifying the outlier sentence among related statements.
Sentences 1, 2, 4, and 5 focus on: Human-driven solutions, interventions, and sustainable practices to address environmental challenges (urban planning, circular economy, waste management, green policies).
Sentence 3 focuses on: Environmental damage and ecosystem disruption caused by climate change (coral bleaching and marine biodiversity loss).
Option 1 (Sentence 5): Discusses government green infrastructure policies—aligns with solution-oriented sustainable development theme.
Option 2 (Sentence 3): Describes coral bleaching and marine ecosystem damage—focuses on environmental problems, not human solutions.
Option 3 (Sentence 4): Discusses waste-management innovation in city planning—aligns with solution-oriented urban sustainability theme.
Option 4 (Sentence 2): Discusses circular economy and product design—aligns with solution-oriented industrial sustainability theme.
Hence, Option 2 (Sentence No. 3) is correct.
Sentence 3 is the outlier because it describes the consequences of environmental damage to natural ecosystems, while all other sentences discuss proactive human solutions and sustainable development strategies.
