A.I. Explanation:

Option 1: "To offer professional swimming lessons only"

Explanation: This option is incorrect because the text states that the 'Fit & Active' program includes a variety of activities, not just swimming lessons. The primary aim is broader, focusing on promoting a healthier lifestyle rather than limiting it to one specific activity.

Option 2: "To promote a healthier lifestyle among residents"

Explanation: This option is correct as the text explicitly mentions that the program is tailored to encourage residents of all ages to embrace a healthier lifestyle. This aligns directly with the main idea of the text, which emphasizes health and fitness for the community.

Option 3: "To increase the community centre's revenue"

Explanation: This option is incorrect because the text does not mention any financial goals or revenue generation as part of the program's aims. The focus is on health and community engagement, not profit.

Option 4: "To provide certification courses for fitness instructors"

Explanation: This option is incorrect as the text does not indicate that the program includes certification courses for fitness instructors. Instead, it focuses on activities for residents, which does not support this claim.
