“The role of the community center has evolved to include job training programs.”
In Part 3 articles about technology, culture, or institutions, 'evolve' signals gradual change over time rather than a single sudden event. Recognizing this distinction helps you match a question about long-term development to the correct paragraph, rather than one describing a specific incident.
Synonyms: develop, progress, gradually change
