Questions: Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. I wanted to test the effects of vitamin C on colds, so I gave the treatment group vitamin C and gave the control group vitamin D. Choose the correct answer below. A. The statement makes sense. The treatment and control groups are receiving different treatments. B. The statement does not make sense. The control group should only receive a placebo, not another treatment. C. The statement makes sense. The experiment has both a control group and a treatment group. D. The statement does not make sense. The vitamin C should be given to the control group, not the treatment group.

Solution Steps

To determine whether the statement makes sense, we need to understand the purpose of a control group in an experiment. A control group is typically used to provide a baseline for comparison and should not receive any active treatment that could affect the outcome. Instead, they usually receive a placebo. In this case, giving the control group vitamin D, which is an active treatment, does not align with the standard practice of using a placebo. Therefore, the statement does not make sense.

In an experiment, the control group is essential for establishing a baseline for comparison. It should not receive any treatment that could influence the outcome of the experiment. Instead, it typically receives a placebo.

The statement describes an experiment where the treatment group receives vitamin C, while the control group receives vitamin D. Since vitamin D is an active treatment, this setup does not adhere to the standard practice of using a placebo for the control group.

Given that the control group is receiving an active treatment rather than a placebo, the statement does not make sense. Therefore, the correct answer is that the control group should only receive a placebo, not another treatment.
