Which weapon detail is linked to Rathbone's crime?

• A. He used a knife
• B. He used a gun
• C. The same weapons Booth used to kill Lincoln
• D. A poison

Answer: (C)

The main idea here is how a single weapon detail connects Rathbone’s experience to Booth’s crime. In the Ford’s Theatre events, Booth’s act of killing Lincoln is defined by the pistol he carried. That same instrument—the pistol—becomes the linking detail for Rathbone’s encounter, since Booth’s plan and the chaotic escape revolve around that weapon. So the detail that binds Rathbone’s incident to Booth’s crime is the pistol used by Booth to kill Lincoln. The other options don’t fit as well: a knife is associated with Rathbone’s defense during the escape but not with the act that ties the two events together; poison isn’t part of the story; and a vague “gun” is less precise than identifying the exact weapon Booth used to kill Lincoln.
