Donte is writing a research paper about the gray wolf, an endangered species in the united states. which is the most effective research question? a) is the gray wolf more or less important than other species in the united states? b) where do gray wolves live in the unites states? c) how does the decline in numbers of gray wolves affect the ecosystem in the western united states? d) are most people in the united states scared of having an encounter with a gray wolf?

c) How does the decline in numbers of gray wolves affect the ecosystem in the western United States?

Explanation:

This is the best choice because it is specific but also allows for enough actual research. Questions B and D are too narrow since they can be answered easily in less than three words. Option A is too broad since the paper will need to compare the gray wolf to all the other species living in the United States. Option C is just right as it will allow Donte to show the effects of the declining numbers of grey wolves on the ecosystem.
