A student is choosing among possible commentary sentences for an AP-style argument about public transit and dignity. The claim is that public transit arguments are strongest when they treat riders as people managing time, work, and care responsibilities. Evidence: Source A profiles a nursing assistant who waits forty minutes after a night shift; Source C reports that riders on the same route missed child-care pickups when evening buses ran late. Which choice most precisely explains how the evidence supports the line of reasoning while avoiding summary or overreach?
