Which of the following is not an AI language?

Question

UnlockIAS · Accepted Answer

Correct — B or D, both accepted (grace question). The question asks which option is NOT an AI language, and two of the four options qualify, so MPPSC's final key accepted either. (B) OOP is not a language at all — it stands for Object-Oriented Programming, a programming paradigm (a style of organising code around objects and classes) that languages such as C++, Java and Python implement. (D) VBI is not a recognised programming language either — no AI language of that name exists; in electronics and broadcasting the acronym stands for Vertical Blanking Interval, and even if a candidate read it as VB (Visual Basic), that is a general-purpose applications language, not an AI language. Since neither B nor D can be defended as an AI language, the commission gave the mark for both.

Why the other options are wrong — (a) LISP is the classic AI language, so it cannot be the answer to a 'not an AI language' question. Created by John McCarthy in 1958, it is built around list processing and symbolic manipulation — exactly what early AI work on reasoning and knowledge representation needed.  (c) PROLOG is the other standard AI language, so it too cannot be the answer. Developed in 1972 by Alain Colmerauer and Philippe Roussel at Marseille, it is a logic-programming language — you state facts and rules and the system infers answers — and it was the language of choice for expert systems and Japan's Fifth Generation Computer Systems project.

Concept: Programming languages are grouped by generation and by paradigm, and exams mix the two up on purpose. By generation: 1GL is machine code, 2GL assembly, 3GL general-purpose high-level languages (C, COBOL, PASCAL, BASIC), 4GL problem-oriented languages such as SQL, and 5GL the constraint/logic languages associated with artificial intelligence — LISP and PROLOG being the standard examples. A paradigm, by contrast, is a style of writing code: procedural, object-oriented (OOP), functional, logic. OOP is a paradigm, never a language.
