Explanation:

The operable principle in W3C's Web Content Accessibility Guidelines (WCAG) focuses on making user - interface components and navigation operable. Since Geoffrey has a motion disability and can't use a regular keyboard but can use a touch - screen (an alternative input method), the touch - screen helps achieve the operable principle by providing an accessible way to interact with the computer.
