I am preapring for an exam and having tests. One of the questions in one of the tests was like that:
The air hostess ... the passengers to fasten their seat belts until after the plane ... off.
The right answer is "asked" - "had taken" but I am not sure why. It seems like when the hostess asks plane did not take off yet and she wants the passengers to be fastened even after the plane take off. Why it is not "is asking" and "will take off"? I might be in the same plane and telling to my grandparent who hardly hears.
