What are the preconditions that/which may enable Benin to recover these treasures?
An English grammar book written by a Chinese says that in a What-question sentence only that rather than which should be used to begin an attributive clause. Can which be used too? Thank you in advance.
(He also says that that rather than who goes with a Who-question, which I found, in the Macmillan Dictionary, is not the case:
Who's the comedian who took my drink? || Who was the actor who played Romeo?)

What did he do that made you angry?
(rather than ?...which made...)
Who did you talk to that gave you such good advice?
(rather than: *...who gave...)
i.e. where the interrogative pronoun itself is the antecedent of the relative.
In your cited sentence, where the antecedent is the NP 'preconditions', either pronoun would be possible (although, that said, 'that' would still be the more natural choice).
