premise: For the school paper, five students—Jiang, Kramer, Lopez, Megregian, and O'Neill—each review one or more of exactly three plays: Sunset, Tamerlane, and Undulation, but do not review any other plays. The following conditions must apply: Kramer and Lopez each review fewer of the plays than Megregian. Neither Lopez nor Megregian reviews any play Jiang reviews. Kramer and O'Neill both review Tamerlane. Exactly two of the students review exactly the same play or plays as each other. If Jiang does not review Tamerlane, then which one of the following must be true?
hypothesis: Lopez reviews Undulation.
