Which of the following services incurs death by divine judgment for a stranger?
A stranger is liable for death only for four complete services: sprinkling, burning, pouring the water, and pouring the wine. Receiving the blood and salting are services that have subsequent work — they incur only lashes. Slaughtering is completely valid for a stranger.
Question 2
How much incense must a stranger burn in the Holy of Holies on Yom Kippur to incur death?

Question 3
What is the ruling for a stranger who arranged the altar on the altar?
Arranging the altar is considered sacred service and is invalid for a stranger. If a stranger arranged it, he must dismantle it and return to the priest to rearrange it. Unlike slaughtering and lighting the Menorah, which are valid for a stranger.
Question 4
What is the ruling for a priest who served idolatry inadvertently and repented completely?

Question 5
How many factors invalidate a person from serving in the Temple according to Rambam's summary of Chapter 9?
Rambam lists in Halacha 15 eighteen factors that invalidate from service, from one who serves idolatry to one who serves with his left hand. Most of them — if they served — their service is invalid, except for three whose service is valid post-facto.
