Answer:
D. Who were some of Martin Luther King's major influences?
Explanation:
According to the example given, Mackenzie is writing a research paper on Martin Luther King Jr and has compiled evidence about some aspects of his life and beliefs.
From what she gathered, he went to India in 1959 to learn more about the non-violent approach of Mahatma Gandhi and he was also inspired by Henry David Thoreau's essay "On Civil Disobedience".
Therefore, based on the evidence, the most logical research question Mackenzie could use to frame her inquiry would be "Who were some of Martin Luther King's major influences?"
