#### Answers

 41 Answer : (b) Reason  :       ‘Satisfiable’ property is a  statement is satisfiable if there is some interpretation for which it is true. 42 Answer : (c) Reason  :       Two literals are complementary if They are identical but of opposite sign. 43 Answer : (e) Reason  :       Consider a good system for the representation of knowledge in a particular domain. The properties should be Representational Adequacy,Inferential Adequacy,Inferential Efficiency and Acquisitional Efficiency 44 Answer : (d) Reason  :       Transposition rule- From P → Q, infer ~Q → ~P 45 Answer : (a) Reason  :       Third component of a planning system is to detect when a solution has been found. 46 Answer : (a) Reason  :       Statistical reasoning is the representation is extended to allow some kind of numeric measure of certainty to be associated with each statement. 47 Answer : (a) Reason  :       In default logic, we allow inference rules of the form:(A : B) / C 48 Answer : (a) Reason  :       In Baye’s theorem,  P(Hi|E)  is the probability that hypotheses Hi is true given evidence E. 49 Answer : (d) Reason  :       Default reasoning is another type of non-monotonic reasoning 50 Answer : (a) Reason  :       Generality is the measure of ease with which the method can be adapted to different domains of application.
