Which revision to Sentence 3 most clearly expresses both the writer's recommendation and the constraint that the next sentence addresses?

1Local archives naturally collect documents connected to major institutions and public events. [Sentence 1] City council minutes, election records, and photographs of landmark buildings can tell future researchers a great deal about a community.

2[Sentence 2] Yet a town's daily life also leaves behind evidence that rarely looks important at the moment it is created. Restaurant menus record prices and changing tastes. Bus schedules show which neighborhoods were connected and how often. Flyers reveal which concerts, meetings, language classes, and services residents could actually find. Even a handwritten notice taped to a shop window can preserve information that no formal report contains.

3[Sentence 3] Because such materials are temporary, archives should establish simple procedures for collecting a small, representative sample of them. The collection does not need every receipt or every flyer. Selection is part of archival work. A rotating set of neighborhood businesses, transit routes, community organizations, and public notices could provide a record broad enough to be useful without overwhelming storage systems.

4[Sentence 4] Future historians will still need official records, but those records become more informative when they can be read beside the traces of ordinary routines.
