Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery.
