The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds,
and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by
reducing the conversion of forests and wetlands to cropland. Opponents of pesticide use claim that pesticides
degrade water and soil quality and that other modern agricultural techniques and practices are responsible for the
improved crop yields in recent years.

(iii) Identify the control.
(iv) Identify the dependent variable.
(b) Describe experimental results that would lead you to reject your hypothesis in part (a)(i). (Be specific.)
