In a backward chaining system you start with the initial facts, and keep using the rules to draw new conclusions (or take certain actions) given those facts. A. True B. False

The correct answer is False.

In a backward chaining system, you start with the goal and keep using the rules to find the initial facts that would satisfy the goal.

For example, if the goal is “Is it raining?”, the system would start by looking for rules that have “raining” as the conclusion. If it finds a rule like “If it is cloudy, then it is raining”, it would then try to find facts that support the premise “It is cloudy”. If it finds a fact like “The sky is overcast”, then it would

If the system cannot find any rules that have “raining” as the conclusion, or if it cannot find facts that support the premises of any of the rules, then it would conclude that “It is not raining”.
