Verified step by step guidance

1. Step 1: Understand the definition of a nonaqueous solution. A nonaqueous solution is one where the solvent is not water.
2. Step 2: Identify the solvent in each given example. For vinegar, the solvent is water; for carbon dioxide dissolved in water, the solvent is water; for salt dissolved in water, the solvent is water.
3. Step 3: For sugar dissolved in ethanol, the solvent is ethanol, which is not water, making it a nonaqueous solution.
4. Step 4: Conclude that the example with a solvent other than water (ethanol in this case) is the nonaqueous solution.
5. Step 5: Therefore, sugar dissolved in ethanol is an example of a nonaqueous solution.
