1. This is apparent from the fact that although the Kohen Gadol entered the Kodesh ha'Kodashim once a year, no one entered the area above it except once or twice every seven years (for maintenance).
2. This was done in order to prevent transgressing Me'ilah by billing for more than they actually gave.

4. However, the same Korban Pesach may be eaten by two different groups (of people designated beforehand to eat it) in two different places, as long as each person remains with that group in that group's place while eating the Korban Pesach.
5. However, Rebbi Shimon maintains that one Korban Pesach may not be eaten by two different groups.
