In this experiment, the researcher is manipulating the variable of alcohol consumption (independent variable) and observing its effect on memory (dependent variable). Therefore, option B is the correct answer. Option A and C are incorrect because memory is the dependent variable, and Germans are not a variable in this experiment. Option D is incorrect because alcohol consumption is the independent variable, not Germans. Option E is incorrect because the dependent variable in this experiment is memory, not exam performance.
