I think that option one would be the best for everyone, as some students can't learn without having a teacher explain it to them in person. I think another option would be to remodel schools to be able to accommodate this, such as putting Plexiglass up in places that students would be considered "too close". Or maybe have all the students' temperatures taken before entering. Maybe have a sheet of paper students must fill out saying that they haven't had symptoms. If a student is suspected to have covid, they should be sent home immediately and have an online substitute for classes, and not be counted absent.
