Note that for this question, you can in addition use ``land" for the symbol A ` `lor" for the symbol V ``Inot" for the symbol- Given the following three sentences: A) Every mathematician is married to an engineer. B) A bachelor is not married to anyone. C) If George is a mathematician, then he is not a bachelor. a) Convert A,B,C into three FOL sentences, where Mn(x): x is a mathematician. Er(x): x is an engineer. Md(x,y): x is married to y. Br(x): x is a bachelor. george: George is a constant. b) Show that A does-not-entail C. (Hint: Consider defining an interpretation / such that / models A, but does-not-model C.) c) Show that (A,B) entails C. (Hint: For a given interpretation I, consider two difference cases, the case where Mn(george) is true, and the case Mn(george) is false. For both cases, argue that it is always that I models C). d) Convert A,B, Inot C into a set of clausal forms, number your clauses. (Note that C is negated here!) e) Derive the empty clause from the set of clauses obtained in d), using resolutions. Your answer should be in clearly steps, one example step is like: Step 5: C3 resolves with C7 on literal L, with substitution x/george, resulting C8: [Er(x)].

e. Problem 5. Devise a function that receives a string and computes how many asterisks are in the string with a recursive method. For instance, if the input is "Able was I ere ***Elba", the function should output 3. If the input is "Peanuts", the function should return 0. Approach: Let's assume the signature of our function is countAsterisks(s) where s is the input string. In the body of your function, check if s[0] is equal to an asterisk. If the string contains only a single character and it is an asterisk, return 1. If the string contains only a single character and it is not an asterisk, return 0. If the string is longer than one character, determine if the first character is an asterisk and count it if this is the case. Then, create a new string s1 that is the same as the input string s but without the first character. Recursively call countAsterisks (s1) and return the value returned from this recursive call, plus one (if there is an asterisk in s[0]). Also, writing any explicit…
