A. The purpose of ‘adjustment’ was to facilitate India’s integration into the global economy.
B. Then, in 1991 came the dramatic announcement of a new economic policy, accompanied by a package of steps to be taken for ‘structural adjustment’ of the Indian economy.
C. When liberalisation of the economy started to receive common consent in the mid-1980s, few people thought of examining what it would mean for education.
D. Even then, education didn’t receive specific attention.      

A cannot be the first sentence of the passage clearly, as it talks about some purpose which is not discussed earlier. C should come at the first place, as it gives the foundation of the discussion; telling us about liberalisation in the mid-1980s and how perhaps no one thought it would benefit in education sector. B comes second, correctly placed, letting us know about the new economic policy of 1991 and how taking steps was necessary for ‘structural adjustment’ of the Indian economy. A should come at third, as it tells the necessity of such structural adjustments. D correctly concludes the passage. AC is the pair to be interchanged. Hence, option C is the correct answer.
