What is the closest meaning of the word "corroborated" in the sentence: "The witness corroborated the suspect's story."?

The term "corroborated" refers to the act of confirming or supporting a statement, theory, or finding with additional evidence or information. In the context of the sentence, when it states that "the witness corroborated the suspect's story," it implies that the witness provided additional support or validation for what the suspect claimed. This alignment strengthens the credibility of the suspect's narrative because it suggests that the witness's account aligns with or verifies the details of the story.

In contrast, the other options do not convey this meaning. To contradict would imply disagreement or opposition to the suspect’s story, which does not support the idea of corroboration. Adding to could suggest providing more information without confirming its accuracy, which doesn't fully capture the act of verification that "corroborated" entails. Questioned implies doubt and skepticism rather than providing support or evidence, again not aligning with the meaning of corroboration. Thus, the concept of verification most accurately reflects the role of the witness in affirming the suspect's story.
