Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: Under the statute, a child born abroad to an unwed American mother is automatically considered a U.S. citizen. But the child of an unwed American father has no citizenship rights unless the father takes the affirmative step of acknowledging paternity and formally agrees to provide support until the child turns 18.
Student:
What event has already happened?
