About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “The following statement describes a specific concept. What is it called? a classification of formal grammars into four types based on their generative power.”
The accepted answer is D. Chomsky hierarchy. The following statement describes a specific concept What is it called a classification of formal grammars into four types based on their generative power is answered by Chomsky hierarchy option D Option A Context-free grammar does not match the stem it is a near-miss used to catch incomplete recall of Chomsky hierarchy Option B Turing machine does not match the stem it is a near-miss used to catch incomplete recall of Chomsky hierarchy Remaining alternatives Alphabet fall outside the same rule and should be eliminated once Chomsky hierarchy is identified Theory of Computation Automata questions of this type reward precise definitions rather than approximate associations Theory of Computation Automata recall of this distinction is a regular item in FPSC PPSC.
