Research studies are usually trying to discover what difference, if any, a given change has on the subjects of the study. Since nothing is done to the control group they provide an unchanged group to compare the changed group with.

For example: If i was trying to prove that 30 mins of exercise a day made for happier people, my control group would be the people that are not doing the 30 mins of exercise.

Farmers in the US, especially wheat farmers, saw a decline in the prices paid for their crops and increased production. The higher supply had the opposite effect of what was intended, by driving prices even lower.
