A.I. Explanation:

Option 1: "To increase visitors' physical activity"

Explanation: This option is incorrect because the text does not mention physical activity as a goal of the Quantum Discovery Centre. The focus is on science education and engagement rather than physical exercise.

Option 2: "To focus solely on space exploration"

Explanation: This option is incorrect because the text clearly states that the centre features multiple galleries, including Space Exploration, Robotics, Human Biology, and Environmental Science. Therefore, it does not focus solely on space exploration.

Option 3: "To make science accessible and engaging"

Explanation: This option is correct as the text explicitly states that the centre aims to inspire future generations of scientists by making science accessible and engaging. This aligns perfectly with the primary aim described in the brochure.

Option 4: "To promote virtual reality technology"

Explanation: This option is incorrect because while the centre includes interactive exhibits and virtual surgeries, the primary aim is not to promote virtual reality technology specifically, but rather to make science accessible and engaging.
