To determine the greatest possible error for a measurement of 2 cups, we first need to clarify the context of the measurement and the precision of the measuring instrument used.

In general, the greatest possible error, often referred to as the *absolute uncertainty*, is typically expressed as a fraction of the smallest increment or division on the measuring tool. For example:

1. **If the measurement is precise to the nearest cup**, the greatest possible error would be ±0.5 cups. This means the true value could range from 1.5 cups to 2.5 cups.

2. **If the measurement is precise to the nearest half cup**, the greatest possible error would be ±0.25 cups, so the range would be 1.75 cups to 2.25 cups.

3. **If using a measuring cup that is marked with eighths or sixteenths of a cup**, the greatest possible error would correspond to that smallest division.

Without additional specifics about the measuring tool's precision, a common assumption would be that the measurement is to the nearest cup, which yields a greatest possible error of ±0.5 cups. Therefore, the true measurement could potentially be within the range of 1.5 to 2.5 cups.

If you have more information regarding the precision of the measurement (such as whether it's to the nearest 1 cup, 0.5 cup, etc.), we could provide a more specific greatest possible error.
