With steady economic growth, higher literacy and increasing skill levels, the number of Indian middle-class families has gone up exponentially. Direct results of the affluence have been changes in dietary patterns and energy consumption levels. People have moved to a higher protein-based' diet like milk products, fish and meat, all of which need significantly more water to produce than cereal based - diets. Increasing use of electronic and electric machines/gadgets and motor vehicles needs more and more energy and generation of energy needs water.

Correct Option (C)

The passage elucidates how economic growth, increased literacy, and higher skill levels in India have led to greater affluence among middle-class families. This affluence, in turn, has resulted in significant shifts in dietary patterns (towards protein-based diets) and increased energy consumption (due to more electronic devices and motor vehicles). These changes in consumption habits and lifestyle are direct manifestations of altered cultural and social behaviour. Option (C) broadly encapsulates this underlying principle, stating that modern technological developments (which are often catalysts for economic growth and the availability of new products) contribute to changes in people's cultural and social behaviour. The passage provides specific examples of these behavioural shifts and their resource implications.

Incorrect Options:

• Option (A): The passage describes the observed shift away from traditional cereal-based diets and its water implications. It does not advocate for policy interventions or persuade people to maintain specific dietary patterns. Its focus is descriptive, not prescriptive.
• Option (B): While the passage identifies increased water demand for agricultural production and energy generation as a consequence of changing consumption, it primarily focuses on the behavioural shifts driving this demand. This option proposes a solution or a necessary focus for the future, rather than reflecting the core analysis of the passage regarding consumption patterns.
• Option (D): The passage highlights the escalating demand for water due to altered consumption patterns. This statement identifies a critical implication and a necessary response to the situation described. However, the central theme of the passage is the cause of increased water demand through changing behaviours, not the advocacy for specific water management practices as its primary crux.
