The following are multiple choice questions (with answers) about medical knowledge.   The authors sought to determine whether the manic/mixed episode distinction in patients with bipolar disorder runs true over time. Over an 11-year period, the observed distribution of manic and mixed episodes (N=1,224) for patients with three or more entries in the management information system of a community mental health center (N=241) was compared to the expected distribution determined by averaging 1,000 randomly generated simulations. Episodes were consistent (all manic or all mixed) in significantly more patients than would be expected by chance.   **Question:** Does the manic/mixed episode distinction in bipolar disorder patients run true over time?   (A) Yes   (B) No   (C) Maybe
