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? If you are still confused, see the following example:
Passage: I submitted the hit. The hit was approved, and then I was paid.
Solution: What happened after I submitted the hit?
Reason: This is a valid temporal question based on the given paragraph. Events approved and paid have a temporal relation "after" with the event submitted.

Now, solve this instance: Passage: An OPEC spokesman suggested Thursday that Sudan could join in March as a 13th member after approval from new president Omar al Bashir, while a membership bid by South American producer Ecuador must clear similar political obstacles. "Both Angola and Sudan feel that OPEC membership will give additional political benefit and protection, while for Ecuador there has to be an additional motive," said John Hall.
