    A farmer wants to know the effects of a new fertilizer on his crop of butter beans. One year, he fertilizes 1 4 of his crop (A) with the new fertilizer, 1 4 of his crop (B) with the fertilizer he has used in the past, 1 4 of his crop (C) with a mixture of the two fertilizers, and 1 4 of his crop (D) with no fertilizer. Assuming all other factors — sunlight, rainfall, soil composition, etc. — are the same as previous years, what is the control group in this experiment? A) Group A B) Group B C) Group C D) Group D

    Group d, to be able to see what each does to the plant, you need to know what nothing does to it
