an experiment for a new asthma medication was set up into two groups. Group one was given the new drug, while group 2 was given a sugar pill. the sugar pill serves as _________.
The correct answer is a) control. In an experiment, a control group is used as a reference point to compare the results of the experimental group. In this case, the control group was given a sugar pill instead of the new drug. By comparing the outcomes of both groups, researchers can determine whether the new drug has any significant effects on asthma symptoms compared to not receiving any treatment (sugar pill). Hence, the sugar pill serves as a control group in this experiment.
