The selection of final five artefacts for the exhibition should be based on several factors. First, the historical significance of the artefact—how old it is and what story it tells about the past. Second, the cultural importance—whether it represents traditions, customs, or practices of a community. Third, the uniqueness—whether the artefact is rare or has special features. Fourth, the condition of the artefact—whether it can be safely displayed without damage. Fifth, the educational value—whether it can help visitors learn something valuable. The group should discuss each artefact's merits, vote democratically, and ensure diversity in the collection by including different types of objects such as textiles, tools, documents, and decorative items.
