Question

identify the question that the experiment can best answer. does fabric turn darker when soaked in a mixture of black dye and water for 15 minutes compared to 30 minutes? does linen fabric turn darker than cotton fabric when soaked in a mixture of black dye and water?

Explanation:

To identify the best - answerable question, we consider the experimental design. The first question about time - based color change is more easily controlled in an experiment as we can vary only the time of soaking. The second question involves different fabric types which may have inherent differences in dye - absorption rates and other properties that are harder to isolate and control.
