Answer

• Negative control
  Explanation:

• This would be a negative control, with which the results are compared to determine the changes.
• A negative control has no expected response, while in positive control, a known response is expected.
• In the experiment, the rate of fermentation will depend on the ability of yeast to ferment sugars. This rate will be compared with the negative control to determine the change or result of yeast activity of sugar.
