(b) What care should one take when saying the things mentioned in the Mishnah?

(c) How do we resolve the discrepancy between the Reisha of the Mishnah, which requires 'Eiravtem' to be said *before* dusk, and the Seifa, which permits making an Eiruv, even during the dusk period.

(c) How does Gemara resolve the problem?

Why is that?

(a) Dusk might belong to the day, it might belong to the night. We give the dusk period the stringencies of both.
What are the ramifications of the two possibilities?

(b) What is the Din if a man sees Zivus throughout one dusk period?
