Read the passage. The pottery studio bought a machine that could shape identical cups quickly. The owner feared students would stop learning hand-building techniques, but the machine instead handled large orders and left class time for glazing, form, and critique. Students began comparing machine-made cups with handmade ones to see how slight variations changed the feeling of an object. Automation did not simply replace craft; it clarified what craft contributes. Which choice best explains how the passage builds the central idea about craft and automation?
