2)

(a)The Tana now discusses somebody who Toveled in a Mikvah that is found to be short of forty Sa'ah. What does he rule in a case where the Mikvah is situated in ...

1. ... a R'shus ha'Yachid?

2. ... a R'shus ha'Rabim?

(b)Why, in the latter case, does the principle Safek Tum'ah bi'Reshus ha'Rabim, Tahor not apply here?

3)

(a)To which specific case does this stringent ruling apply?

(b)But regarding Tum'ah Kalah, the Tana declares him Tahor. To which of the aforementioned cases does this ruling pertain?
