Question $16$ options:

'TELL' refers to the action of querying the knowledge base to retrieve information, whereas 'ASK' involves the removal of certain facts from the knowledge base.

'TELL' is the command to update the knowledge base with new facts or rules, and 'ASK' is the mechanism for posing questions to the system to infer if certain statements are true.

TELL' is the process of adding new rules to the inference engine, and 'ASK' is the process of querying the current state of the knowledge base.

'TELL' represents the method of instructing the knowledge base to perform actions, while 'ASK' is the command used to halt the inference process.

'TELL' and 'ASK' are both commands used to modify the underlying algorithm of the AI system's inference engine, altering its reasoning pattern.
