Is there a choice here?

Question

Hola!I've been following this and could do with some expert assistance. I was looking at this line:Note that conjunctions o/o bien can either present a person with a choice to make (either one thing/idea or another) or both options are seen as possible. There is a choice to make here:Tiene que venir o tu padre o tu madre. Tu hermano no puede venir a la reunión.Either your father or your mother has to come. Your brother cannot come to the meeting.My question is, is there something implying exclusivity - that it's the father or the mother, but not both? I would assume in English that it could be vague still - it might be the case that there's only room for one person, or it could be that one or both parents come, but a brother isn't suitable.Thank you so much!Ciaran

Hola Ciaran P.
That's a very good question.
In this example, o presents the parents as the available alternatives, but it doesn't necessarily imply that the choice is exclusive (i.e. one parent and not the other).
Tiene que venir o tu padre o tu madre identifies your father and your mother as the people who are able to fulfil the requirement, while your brother is explicitly excluded. In practice, if both parents came, the sentence would still be true because the requirement that at least one of them comes has been met.
If the speaker wanted to make it absolutely clear that only one of them should come, they would normally need to add extra context, for example:
Tiene que venir solo tu padre o tu madre
or
Uno de los dos tiene que venir.
So the sentence doesn't by itself force an exclusive interpretation; the context determines whether one or both parents may come. The key point of the lesson is that o...o presents alternatives, whereas o bien...o bien presents alternatives that are both considered possible, often in a more formal style.
We appreciate your thoughtful question!
