Question 1 · Single choice — select one

A soil layer contains (i) pottery fragments, (ii) a distinct charcoal-rich horizon, and (iii) fine sediment deposited above both. What is the most reasonable interpretation?

The pottery and charcoal were transported together by a single flood event. Human activity occurred first, followed by a fire event, and later by flooding or sediment deposition. The charcoal layer must be natural and unrelated to human activity. The sediment layer must be older than the artefacts because it is located above them.
