Choice B is the best answer. In (lines 31-35"In...proper"), the authors argue that beekeep-ers' use of insecticides to control mite infestations may be harmful to some bees. The authors then state, "We further postulate that the proper dosage necessary to prevent mite infestation may be better left to the bees" (lines 35-37"mite... avoid"). In this context, the authors "postulate," or put forth the idea that the bees may naturally control mite infestations better than insecticides.
Choices A, C, and D are incorrect because in this context, "postulate" does not mean to make an unfounded assumption, question a belief or theory, or conclude based on firm evidence.
