If a rule-based expert system attempts to prove a statement but its inference engine finds no applicable rule, which outcome will inevitably follow?

💡 Explanation

The system must declare the statement unprovable because the inference engine, which follows a specific set of logic, cannot proceed without an applicable rule. Therefore, the system returns a 'not provable' result, rather than learning a new rule or experiencing a memory error, as these depend on different system architectures.
