Numerical answer
Four of the five sentences below, labelled 1-5, form a coherent paragraph. Identify the ONE sentence that does not fit and enter its number.
1. Many cities have begun offering curbside collection of food scraps and yard waste for composting, diverting material that would otherwise decompose in landfills and release methane.
2. Composting converts organic waste into a nutrient-rich soil amendment that can be used in parks, community gardens, and municipal landscaping.
3. Electric vehicle sales have grown rapidly in the past five years as battery costs have fallen and charging infrastructure has expanded.
4. Participation rates in curbside composting programs tend to rise sharply once cities pair pickup with clear, simple sorting instructions for residents.
5. Some studies suggest that composting programs, when well designed, can reduce a city's landfill-bound waste volume by fifteen to thirty percent.

Show answer and solution
Answer: 3
Sentences 1, 2, 4 and 5 all discuss municipal composting programs — how they work, their benefits, and how participation and impact can be improved or measured. Sentence 3, about electric vehicle sales and battery costs, is an unrelated topic and breaks the paragraph's coherence.
