i want someone to solve this questions Q1: Suppose KB with these rules and facts: Rules: R1: IF: fever(x) & red_spots(x) THEN: measles(x) R2:IF: runny_nose(x) THEN: cold(x) R3:IF: cold(x) THEN: contagious(x) R4: IF: measles(x) THEN: contagious(x) R5: IF: meningitis(x) THEN: contagious(x) R6: IF: contagious(x) & dangerous(x) THEN: isolated(x) R7: IF: fever(x) & stiff_neck(x) THEN: meningitis(x) R8: IF: meningitis(x) THEN: dangerous(x) Facts: runny_nose(mary) red_spots(mary) fever(mary) stiff_neck(john) fever(john) a) What can be derived from this knowledge base by forward reasoning? Q2: Suppose KB with these rules and facts: R1: IF A,THEN E R2: IF B AND F , THEN G R3: IF C AND E,THEN F Initial facts: A, B, C, D. 1) Show how can you use “backward” to determine the truth, or otherwise, of fact G. 2) Show how can you use “forward” in this case to determine new facts. Q3: You are given a set of rules and fact for answer this question: Should we buy a house or not? by using forward chaining R1: IF inflation is low THEN interest rates are low R2: IF inflation is high THEN interest rates are high R3: IF interest rates are high THEN housing prices are high R4: IF housing prices are high THEN do not buy a house F1: high inflation rate
