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
para as well.
