Insectivorous plants, which unlike other plants have the ability to trap and digest insects, can thrive in soils that are too poor in minerals to support noninsectivorous plants. Yet the mineral requirements of insectivorous plants are not noticeably different from the mineral requirements of noninsectivorous plants. The statements above, if true, most strongly support which one of the following hypotheses? ['Insectivorous plants can get some of the minerals they require from the insects they trap and digest.', 'Insectivorous plants thrive only in soils that are too poor in minerals to support noninsectivorous plants.', 'The insects that insectivorous plants trap and digest are especially abundant where the soil is poor in minerals.', 'The types of minerals required by noninsectivorous plants are more likely than are the types of minerals required by insectivorous plants to be found in soils poor in minerals.']
