Which two Greek roots form the basis of the term 'chiropractic'?

• A. Cheir and Praktos
• B. Kai and Nomos
• C. Osteo and Path
• D. Neuro and Dyno

Answer: (A)

The question is testing how chiropractic got its name from Greek roots that describe what the practice involves. One root means hand (cheir), and the paired root here, Praktos, comes from praktikos, meaning done, practiced, or action. Put together, these roots convey “hand practice” or “done by hand,” which matches the manual adjustments chiropractors perform. The other options point to different ideas—bones (osteo) and disease or suffering (path), nerves (neuro), or power/force (dyno)—which don’t describe the hands-on, practitioner action that chiropractic implies.
