Explanation
Correct answer: D.
Choice D is the best answer because the sentence makes and supports a generalization about honeybees. It claims that honeybees living in urban areas are more likely to thrive than rural bees, and it supports the claim with information about the effect of a varied diet on urban bees’ immune systems.
Why the other choices are wrong
Choice A
Choice A is incorrect. While the sentence makes a generalization, it doesn’t mention honeybees.
Choice B
Choice B is incorrect. While the sentence provides data about honeybee survival, it doesn’t make a generalization about honeybees based on this information.
Choice C
Choice C is incorrect. While the sentence makes a generalization about honeybees’ diets and immune systems, it doesn’t provide adequate support for this generalization.
