A.I. Explanation:

Option 1: "Leisure means spending all your time doing fun activities."

Explanation: This option is incorrect because the text does not define leisure as solely about fun activities. Instead, it emphasizes that leisure is a concept that evolves and varies across generations, including activities like prayer and family time, which may not be considered 'fun' in the conventional sense.

Option 2: "People work in the office during leisure time."

Explanation: This option is incorrect as the text does not mention work during leisure time. It focuses on how different generations perceive leisure differently, highlighting activities that are typically associated with leisure rather than work.

Option 3: "Perception of leisure is different for your generation and your grandparent’s generation."

Explanation: This option is correct because the text explicitly states that different generations have different ideas of what leisure means. It provides examples of leisure activities preferred by older generations compared to the current generation, thus supporting the notion of differing perceptions.

Option 4: "Activities to do in leisure time have been the same for some decades."

Explanation: This option is incorrect because the text argues that the nature of leisure activities changes over time, indicating that activities are not the same across decades. It highlights the evolution of leisure activities from one generation to another.
