While researching student news podcasts, a student has taken these notes: - Media teacher Elena Brooks tracked downloads for a student news podcast. - Brooks found that episodes featuring interviews with local officials were downloaded more often than episodes without interviews. - A civics teacher's survey showed that some listeners later discussed local issues in class. - Brooks did not measure whether downloads led to increased civic knowledge. The student wants to use Brooks's download finding without unsupported impact claims. Which choice most accurately uses information from the notes to accomplish this goal?
