When soil is plowed in the spring, pigweed seeds that have been buried in the soil all winter are churned up to the surface and redeposited just under the surface. The brief exposure of the seeds to sunlight stimulates receptors, which have become highly sensitive to sunlight during the months the seeds were buried in the soil, and the stimulated receptors trigger germination. Without the prolonged darkness, followed by exposure to sunlight, the seeds do not germinate. The statements above, if true, most strongly support which one of the following statements about a field that will be plowed in the spring and in which pigweed seeds have been buried in the soil all winter? ['Fewer pigweed plants will grow in the field if it is plowed at all than if it is plowed only at night.', 'Fewer pigweed plants will grow in the field if it is plowed only at night than if it is plowed during the day.', 'Fewer pigweed plants will grow in the field if it is plowed just before sunrise than if it is plowed just after sunset.', 'The pigweed seeds that are churned up to the surface of the soil during the plowing will not geminate unless they are redeposited under the surface of the soil.']
