This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
As-t graph showing s increasing non-linearly then linearly, concave up
Bs-t graph showing s increasing non-linearly then becoming constant, concave up
Cs-t graph showing s increasing non-linearly with ever-increasing slope, concave up
Ds-t graph showing s increasing linearly
✓ Correct answer
A: s-t graph showing s increasing non-linearly then linearly, concave up
