What was the primary purpose of some of the earliest AI programs described in the material?

• A. Diagnose patients as expert systems
• B. Play Jeopardy
• C. Visualize data
• D. Control robotic limbs

Answer: (A)

Early AI emphasized building expert systems that emulate specialized human expertise. The earliest programs were designed to capture the knowledge and decision-making processes of experts in a specific field and apply that rules-based reasoning to real problems. In medicine, this meant diagnosing conditions and suggesting treatments, using curated rules and evidence to imitate clinical judgment. That focus on diagnosing patients and providing expert guidance is why recognizing these programs as diagnostic expert systems best fits what they were created to do.

For comparison, programs that later gained attention for other feats—like playing Jeopardy, visualizing data, or controlling robotic limbs—represent different directions in AI development and aren’t the primary aim of those initial systems.
