Explanation:
Sorry if i am wrong but here is my explanation.
Both archaelogists and historians use sources and evidence to learn about the past.
Archaeologists learn about the past by studying artefacts. These are things people living long ago left behind them (eg. pottery). Artefacts are stored in a museum.
Historians find out about the past by studying written sources (ie what people wrote). Written sources are stored in an archive.
