Why can chronology become confusing if archaeological layers are disturbed?
Answer and explanation
Correct answer: Older and newer objects may be found together outside their original stratigraphic sequence
Stratigraphy normally helps establish chronology because, in an undisturbed deposit, lower layers are generally older than upper layers. Pits, rebuilding, burrowing animals or later human activity can disturb that order and mix materials from different periods. Thus older and newer objects may appear together, making dating uncertain. Option D is correct; the other options misunderstand or ignore stratigraphic disturbance.
