(15) Let M be the language over {a, b, c, d, e, f} accepting all strings so that: 1. There are precisely two e's in the string. 2. Every a is immediately followed by an even number of b's. 3. Every c is immediately followed by an odd number of f's. b's and f's don't occur except as provided in rules 2 and 3. 5. All c's occur after the first e. 4. 6. All a's occur before the second e. 7. In between the two e's there are exactly twice as many c's as a's. Construct a context-free grammar generating M. You do not need an inductive proof, but you should explain how your construction accounts for each rule. 5) We could eliminate one rule from M and make it regular. Which one? Why? (5) Show that the class of context free languages is not closed under intersection by finding two CFLS whose intersection is not a CFL.

The following is a grammar for JH-Lisp 2.1, modified version of the language you encountered in homework 4, with slightly different syntax, and expanded set of functions. It uses underscores rather than spaces, square brackets rather than paren- theses, and words as function names instead of symbolic operators.
