Solution
Crop rotation helps control pest populations primarily because pests are often crop specific. This means that they thrive on specific types of crops. When farmers rotate their crops, the pests cannot find their preferred food source and their populations cannot continue to increase. Therefore, the correct answer is: "Pests are crop specific, so their populations cannot keep increasing."
