Instructions: In this task, a passage will be given and the goal is to generate a question about temporal relations based on that passage. A temporal relation describes the relation between two things with respect to time e.g., something happens/starts/terminates/... immediately/shortly/usually/... before/after/during/... something else.
 Your question should include an event, or ask about an event, and should not be a yes/no question.
Input: Passage: But with the task-force investigation just getting under way, officials have been careful not to draw any firm conclusions, leaving open the possibility of a serial killer in some of the cases. There have been no arrests in any of the slayings.
Output:
