Question

You want to test a new drug that supposedly prevents sneezing in people allergic to grass. What would be a good control?

Answer 1

A good control for testing a new drug that prevents sneezing in people allergic to grass would be a placebo control.

Step-by-step explanation:

A good control for testing a new drug that supposedly prevents sneezing in people allergic to grass would be a placebo control. In this case, the control group would receive a substance that looks and tastes like the drug but does not have any active ingredients. By comparing the effects of the actual drug to the effects of the placebo, researchers can determine if the drug is truly effective in preventing sneezing.

Answer 2

You need to have two groups when completing an experiment. One of them being the control group, which should have nothing changed. Whilst the test group should be given the drug and the two groups results compared. So therefore the control in this case is: a group of people with an allergy to grass on no medication and not on the new drug.
