Using DCG notation, write a grammar for a language that is just like Є1, except that it enforces agreement between the subject and verb of a sentence and thus does not generate “I smells the wumpus.”
Augment the E1 grammar so that it handles article—noun agreement. That is, make sure that “agents” is an NP, but “agent” and agents” are not.
