Exercise 1.3 (20pt) For the first-order logic domain below: "Every son of my father is my brother." 1) (14pt) Discuss all the interpretations (when there are too many possibilities, provide a few examples and explain). Assume the following constants: C={Sam,John,Me}, domain elements: {o1,o2,o3,o4}, function: {f(x) : father of x}, and predicates: {S(x,y):x is the son of y;B(x,y):x is the brother of y} 2) (6pt) Provide an interpretation in which "Every son of my father is my brother. " is true and another interpretation where it is false
