"I answer the impossible question."
Translation:Io rispondo alla domanda impossibile.
Translate it as "I respond to the impossible question." Then the use of "alla" makes sense.
No. Rispondere is an intransitive verb, meaning that it doesn't take a direct object.
Actually intransitive verbs don't have objects at all. You meant "rispondere" is an indirect transitive verb. Anyway, thanks for explaining that.
Why is alla used for the here? Does it have something to do with the use of the verb rispondere? Cheers!
Because it's actually ' respond TO the... '. Take it as ' respond to ' instead of ' answer ' and you should get it each time. Cheers!
