Consider the revision point in this draft. A community shelter is revising a supply-rotation plan. The storage room contains sealed food, hygiene kits, blankets, and batteries donated at different times. [Because the previous inventory listed quantities but not expiration or inspection dates and because newer donations were often stacked in front of older ones, which allowed some supplies to remain unseen until they were no longer usable, the shelter added dated shelf zones and monthly rotation checks.] Long-lasting blankets are inspected for condition rather than expiration. The next paragraph explains donation acceptance. Which revision best explains how the two changes address different parts of the storage problem?
