This is an extension of the question What is the difference between using "de" and "que" for the English word "to"?
Consider the sentence "You have one minute to choose":
Tienes un minuto para elegir.
Taking the information from the other question I would've assumed that para
would be de
because it is an informative statement. I don't think que
can be used because it's not an obligation (I think).
So why is para
being used? And can you flesh out the differences between que
and para
as well.
