A.I. Explanation:

Option 1: "To provide an example of a problem related to the laws of physics that a fine artist must overcome"

Explanation: The author discusses the bronze statues of horses to illustrate a specific challenge that fine artists face regarding the laws of physics. The text states that fine-art objects, while not constrained by physical laws in the same way as applied-art objects, still require an understanding of stability and weight distribution. The example of the cannonball under the raised hoof of the horse statue highlights how artists must address physical challenges to achieve their artistic vision.

Option 2: "To argue that fine artists are unconcerned with the laws of physics"

Explanation: This option is incorrect because the text explicitly states that fine artists must overcome problems related to the laws of physics. The author does not argue that fine artists are unconcerned; rather, it emphasizes that they face unique challenges that require an understanding of physical properties.

Option 3: "To contrast the relative sophistication of modern artists in solving problems related to the laws of physics"

Explanation: This option is incorrect as the text does not discuss modern artists or make any comparisons regarding sophistication. The focus is solely on the challenges faced by fine artists in the context of historical examples, specifically the early Italian Renaissance.

Option 4: "To note an exceptional piece of art constructed without the aid of technology"

Explanation: This option is incorrect because the text does not suggest that the bronze statues were created without technology. Instead, it highlights the use of a cannonball as a practical solution to a physical problem, indicating that technology and understanding of physics were indeed involved in the creation of such artworks.
