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.

Passage: In a letter Wednesday to the Chamber of Deputies, economic affairs minister Hans Wijers said he has reached the "bitter conclusion" that there were "no further prospects" for restoring the Fokker activities. Hence the state is no longer willing to invest, even though it is still prepared to provide technical support for further efforts by Belgian investor Andre Deleye, who said Saturday that he still had some hope of finding some parties to take over Fokker.
