premise: A movie studio is scheduling the release of six films—Fiesta, Glaciers, Hurricanes, Jets, Kangaroos, and Lovebird. No two of these films can be released on the same date. The release schedule is governed by the following conditions: Fiesta must be released earlier than both Jets and Lovebird. Kangaroos must be released earlier than Jets, and Jets must be released earlier than Hurricanes. Lovebird must be released earlier than Glaciers. Which one of the following, if substituted for the condition that Fiesta must be released earlier than both Jets and Lovebird, would have the same effect on the order in which the films are released?
hypothesis: Only Kangaroos can be released earlier than Fiesta.
