Does a non-context-free language exist that doesn't break any of the rules of the pumping lemma for context-free languages? Yes. If a language is finite, it will pass the pumping lemma. No. Since the pumping lemma is used to prove a language is not context-free, a non-context-free language has to break the rules of the pumping lemma. No. If the results of a pumping lemma proof are inconclusive, a bad string was chosen. Yes. Otherwise, we could use the pumping...
