Theory of Computation (Automata)
Choose the correct description of Derivation.
Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: Choose the correct description of Derivation. The correct choice is B. The sequence of production rule applications used to generate a string from a grammar's start symbol.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Theory of Computation (Automata) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Theory of Computation (Automata) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Theory of Computation (Automata) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A finite sequence of symbols drawn from an alphabet.
Why not A: “A finite sequence of symbols drawn from an alphabet.” does not fit this question. The answer is The sequence of production rule applications used to generate a string from a grammar's start symbol..
- B. The sequence of production rule applications used to generate a string from a grammar's start symbol. ✓
- C. A class of languages for which a Turing machine will accept and halt on strings in the language, but may not halt on strings outside it.
Why not C: “A class of languages for which a Turing machine will accept and halt on strings in the language, but may not halt on strings outside it.” does not fit this question. The answer is The sequence of production rule applications used to generate a string from a grammar's start symbol..
- D. A set of strings composed of symbols from a defined alphabet.
Why not D: “A set of strings composed of symbols from a defined alphabet.” does not fit this question. The answer is The sequence of production rule applications used to generate a string from a grammar's start symbol..
Correct answer
B. The sequence of production rule applications used to generate a string from a grammar's start symbol.
Explanation
The sequence of production rule applications used to generate a string from a grammar's start symbol option B is the accepted answer to Choose the correct description of Derivation Option A A finite sequence of symbols drawn from an alphabet does not fit this question Option C A class of languages for which a Turing machine will accept and halt on strings in the language but may not halt on strings outside it does not fit this question Option D A set of strings composed of symbols from a defined alphabet does not fit this question For this Theory of Computation Automata question the accepted answer is The sequence of.
