A neighborhood market began recording which unsold vegetables remained each evening. First, the staff separated items that could be used the next morning from those that had to be removed. They then posted a short list before closing so nearby kitchens could request usable items. After four weeks, the market kept the list but changed the collection time because late requests interrupted cleaning. One reading task asked students to arrange the events. A second asked them to choose a rewrite that preserved who performed each action and why the time changed. A third asked which question could not be answered from the passage. The source text was the same, but each task required different evidence. Time markers supported the order task, actors and conditions supported the rewrite, and the absence of requested information mattered in the final task. Reusing one highlighted sentence for all three would confuse topic familiarity with task-specific proof.
