Choice D is the best answer. In (lines 24-28"such...bees"), the authors provide evidence that a bee colony may be more resistant to mite infections if the bees eat pyrethrums because this diet may help prevent bees from becoming "immu-nocompromised or nutritionally deficient." In (lines 42-50"This...colonies"), the authors sug-gest testing this hypothesis in a trial on honeybees.
Choices A, B, and C do not describe any of the authors' hypotheses.
