This task tests a model's ability to explain fundamental science phenomena (\eg, geological transformations) through instructional diagrams. Generated outputs should identify underlying mechanisms (\eg, DNA's role in genetics) or connections between concepts (\eg, how a headland erodes into caves, arches, and stacks).

I don't quite get how a headland turns into caves, arches, and stacks. Can you generate an image and explain the sequence? Please answer with both visual and textual explanations.
