Discussion
Statement (A) : The concept 'Knowledge industry' was introduced by Fritz Machlup in 1962.
Statement (B) : A systematic model of communication was developed by Watzlawick in 1992.
Answer: B
The answer is (A) is true but (B) is false.
Statement (A) is correct: the economist Fritz Machlup introduced the idea of a knowledge industry in The Production and Distribution of Knowledge in the United States, published in 1962, where he measured the share of the economy devoted to producing knowledge.
Statement (B) has the wrong date. Paul Watzlawick's systemic model of communication was set out with Beavin and Jackson in Pragmatics of Human Communication in 1967, not 1992. With (A) true and (B) false, the options calling both true, both false or only (B) true are all wrong.
