You will be given a definition of a task first, then some input of the task.
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: The portfolio unit of the French bank group Credit Lyonnais told stock market regulators that it bought 43,000 shares of Cie. de Navigation Mixte, apparently to help fend off an unwelcome takeover bid for the company. Earlier yesterday, the Societe de Bourses Francaises was told that a unit of Framatome S.A. also bought Navigation Mixte shares, this purchase covering more than 160,000 shares.
Output:
