(b) ( x )( y ) M ( x,y ). (c) ( y )( x )[ L ( x,y ) N ( x,y )]. (d) ( y )( x )[ M ( x,y ) L ( x,y )]. 2. Suppose that the possible values of p and q are all fruit. Let A ( p,q ) = p tastes better than q , let B ( p,q ) = p is riper than q and C ( p,q ) = p is the same species as q . Translate the following into symbols. (a) There is a fruit such that all fruit taste better than it. (b) For every fruit, there is a fruit that is riper than it.
