Which of the following is NOT a type of Inference rule?
Hypothesis
What is the representation of logical connectives like 'if...then' in propositional logic?
(P → Q)
How are compound statements shown to be equivalent using truth tables?
By analyzing truth values
What is the purpose of Unification in logic?
To make two different logical atomic expressions identical
In the example provided, what does the UNIFY algorithm do?
Returns a unifier for two atomic sentences
What happens if the UNIFY algorithm fails to find a unifier for two atomic sentences?
It returns fail
What does Unification rely on as part of the replacement process?
Finding a substitution
How is Unification related to First Order Inference (FOI) algorithms?
It is a key component of FOI algorithms
What is the outcome of applying a unifier to two atomic sentences using the UNIFY algorithm?
They become indistinguishable
What does Modus Ponens state?
If P and P → Q are both true, then Q is true
Which statement best represents Modus Tollens?
If P → Q is true and ¬Q is true, then ¬P is true
In Hypothetical Syllogism, what can be inferred when P → R and Q → R are both true?
P → R is true
What does Disjunctive Syllogism state?
If P ∨ Q is true and ¬P is true, then Q is false
How can you best describe the relationship between Modus Ponens and Modus Tollens?
They both deal with implications but in opposite directions
In the context of logical inference, what does the statement 'P→Q / P / ∴Q' represent?
Modus Ponens
What is the benefit of combining declarative and procedural approaches in building an agent?
Increased efficiency in the agent's code

Increments the counter by 1
How does a Knowledge-Based Agent (KBA) utilize the 'ASK' function?
To query the knowledge base for a recommended action
What does the counter 't' represent in the generic KBA program?
The number of sentences processed by the agent
What is the purpose of the 'Perform' action in a Knowledge-Based Agent (KBA)?
To execute the selected action based on recommendations
What is a free variable in First Order Logic?

Substitute constant 'a' for variable 'x'
How does First Order Logic use equality when comparing terms?
To show that two terms refer to the same object
