In a study of whether alcohol consumption might affect memory, research participants were assigned to drink either an alcoholic or a nonalcoholic beverage prior to completing a memory test. those who drank the nonalcoholic beverage participated in the condition.

The answer is "Control Condition".

The control condition in a test configuration does not have any treatment or control of the autonomous variable. Individuals relegated to the control group fill in as the premise of correlation for the general population in the test condition. Everything in a control condition is the same as the test conditions aside from that the autonomous variable is missing or held consistent. Assuming that the gatherings were identical before the treatment, any contrasts between the control condition and the test condition can be credited to the impact of the autonomous variable.
