A friend asked me to answer this question: What culture's invasion of the hills that were occupied by two types of settlements was most likely for silver?, using the article: Twenty Palaeolithic sites have been identified in the Mendips, of which eleven represent faunal remains and lithic artefacts recovered from caves. The remaining eight sites refer to surface lithic discoveries, and the artefacts found include points, scrapers, and handaxes. Twenty-seven Mesolithic finds are represented by flint and chert lithics. Large numbers of artefacts have been found near Neolithic, Iron Age, and Bronze Age features, such as the barrows and forts around Priddy and at Dolebury Warren. The caves of Cheddar Gorge have yielded many archaeological remains, as flood waters have washed artefacts and bones into the caves and preserved them in silt. The Cheddar Man, Britain's oldest complete skeleton, was found in Gough's Cave, part of the Cheddar Complex.Within the Mendip Hills AONB, good evidence exists for 286 definite examples of round barrows, including the Priddy Nine Barrows and Ashen Hill Barrow Cemeteries. The Historic England Archive holds over 1,200 entries for the area, and there are over 600 listed buildings, in addition to over 200 scheduled ancient monuments. These protected monuments range from prehistoric barrows and hillforts to the Black Down bombing decoy from the Second World War.Settlement on the Mendip Hills appears to fall into two types. The first, apparent in the Neolithic and Bronze Age Britain periods, and repeated on a small scale in the Middle Ages and post-medieval era, comprised occupation by self-sufficient groups in small communities or isolated farms. The second was represented in the Iron Age Britain and Roman periods by large sites with specialist functions, existing by virtue of their ability to exert power over lowland producers. From the Iron Age onward the ownership of land took on increasing importance, with large landholdings based on the mines or on stock grazing, denying settlers access to the plateau or forcing them off the hills.There is evidence of mining dating back to the late Bronze Age, when there were technological changes in metal-working..., what would be the answer ?
The answer to this question is:
Roman
