Passage Summary: If the jury was still working, the news trucks would be outside; since the trucks are gone, the jury must be finished.

Conclusion: The jury must have reached a verdict.

Reasoning: If a verdict had not been reached, media trucks would be present; however, there are no media trucks present.

Analysis: This argument follows a valid logical structure known as Modus Tollens: If P, then Q; Not Q, therefore Not P. The first sentence sets up a conditional relationship where 'no verdict' (P) requires 'media trucks' (Q). The second sentence observes the absence of the necessary condition (Not Q), leading to the negation of the sufficient condition (Not P). To find the parallel, look for an answer that follows this exact 'If A then B; Not B, so Not A' pattern without any logical errors.
