4 types of questions to be put aside

The four types of questions / possibilities to be put aside and not answered (beyond the limits of our language):
1. Is the universe eternal or do we exist in Nibbana?
2. Is the universe finite or do we not exist in Nibbana?
3. Do we both exist and do not exist?
4. Do we neither exist nor non-exist?
