If I organise an event and allow only people who bought a ticket, how do I construct a sentence with "require" and the subjunctive mood to express the requirement?
- We require that everybody bought a ticket.
- We require everybody to have bought a ticket. (Well, this is not really a subjunctive mood as far as I concern, so I would like to avoid this style. Nonetheless, I'm interested how correct and natural it is)
- We require that everybody have bought a ticket.
- Another option?
Does the answer change if the requirement changes into "people who have ever been to Czechia"?
