A.I. Explanation:

Option 1: "formal and tough dance training"

Explanation: The text states that Fuller had minimal formal dance training, which contradicts the idea of 'formal and tough dance training.' This indicates that her dance style did not stem from rigorous training, making this option correct as it is not characteristic of her dance.

Option 2: "experimentation using color"

Explanation: The text mentions that Fuller focused on the shifting play of lights and colors, indicating that experimentation with color is indeed a characteristic of her dance. Therefore, this option is incorrect.

Option 3: "large and full costumes"

Explanation: The text describes the voluminous skirts or draperies that Fuller wore, which aligns with the idea of large and full costumes. This makes the option correct in terms of being a characteristic of her dance, thus it is incorrect to say it is not.

Option 4: "continuous movement of her costumes"

Explanation: The text states that Fuller kept her costumes in constant motion through her arm movements, which directly supports the idea of continuous movement of her costumes. Hence, this option is also incorrect.

Option 5: "technical virtuosity of movement"

Explanation: Fuller rejected the technical virtuosity of movement in ballet, which is a clear indication that this characteristic does not apply to her dance style. Therefore, this option is correct as it is not a characteristic of her dance.
