Mackenzie is searching for information on the effects of self-driving vehicles on people who live in rural areas. She is unable to find enough material on the topic.

Because Mackenzie cannot find enough information on her specific topic, she should broaden her research question so it covers a larger subject and is more likely to have useful sources. For example, she could research the effects of self-driving vehicles on people in general, rather than only on people in rural areas. Revising her timeline or narrowing the topic would not address the lack of material.
