Consider the writing prompt. Write an informative, research-based essay that explains President John F. Kennedy’s leadership style. Which research source would be the most reliable to use to address the prompt?

A professional historian’s article is the most reliable choice because it is likely based on research and presents an informed analysis of Kennedy’s leadership. The book title makes a strongly one-sided claim, a student report may not be thoroughly researched, and a memoir by Kennedy’s wife offers a personal perspective rather than an independent assessment.
