JavaScript is off, so the frame above already shows the complete comparison: two exactly parallel demand curves, with the $1 price step from $4.50 to $3.50 crossing both at the dotted points. The readout runs the midpoint formula on that step for each curve: the quantity change is identical (ΔQ = 0.57), but curve 2's change is measured against a bigger base quantity, so %ΔQ is smaller and e = 1.33 vs e = 0.67 — same slope, different elasticities. Only the draggable step is inactive in this still image.
