**Question:**(5) If \( L \) is context free, then \( L \cap \lnot L \) must also be context free.- [ ] True- [ ] False**Explanation:**This question tests the understanding of closure properties of context-free languages. Context-free languages are not closed under the complementation operation. Therefore, \( \lnot L \) may not be context-free, and the intersection of a context-free language \( L \) with a non-context-free language \(\lnot L\) is not guaranteed to be context-free. Consider carefully whether the statement is true or false based on these closure properties.

Context-free languages are constructed using context-free grammars, a formal way to define language…
