About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “In computer science, Context-free grammar refers to which of the following?”
The accepted answer is A. A formal grammar in which every production rule has a single non-terminal on its left-hand side.. In computer science Context-free grammar refers to which of the following is answered by A formal grammar in which every production rule has a single non-terminal on its left-hand side option A Option B An automaton that uses a stack to recognize context-free languages does not match the stem it is a near-miss used to catch incomplete recall of A formal grammar in which every production rule has a single non-terminal on its left-hand side Option C A property of a problem indicating whether an algorithm can be constructed that always provides a correct yes no answer does not match the stem it is a near-miss used to catch incomplete recall of A formal grammar in which every production rule.
- A. A formal grammar in which every production rule has a single non-terminal on its left-hand side. ✓
- B. An automaton that uses a stack to recognize context-free languages.
Why not B: “An automaton that uses a stack to recognize context-free languages.” is not correct. The accepted answer is A.
