Explanation: It is distributed in the house.

Explanation (R. Tam): There are two kinds of Ma'aser Oni, like it says in Nedarim (84b) "here we discuss Ma'aser Oni distributed in the house, and here we discuss Ma'aser Oni distributed in the granaries."

Ma'aser Oni is distributed in the house on Erev Pesach, like a Beraisa in Sifri teaches. (It is not found in our Sifri);

Citation (Sifri): One verse says "mi'Ketzei Shalosh Shanim Totzi... v'Hinachta bi'Sh'arecha." This connotes that one leaves it in the granary, and Aniyim come and take it;

Citation (cont.) - Contradiction: Another verse says "Ki Sechaleh Laser Es Kol Masar Tevuascha ba'Shanah ha'Shelishis Shenas ha'Ma'aser v'Nasata..." This connotes that the Ba'al ha'Bayis distributes it, for it says v'Nasata!

Citation (cont.) Resolution: Until Pesach, which is the rainy season, and if he leaves it outside, it will be ruined, he distributes in the house. This is Ma'aser Oni distributed in the house, about which it is written Nesinah;

Citation (cont.): After Pesach, which is the time of Bi'ur, one leaves it in the granary, and it is Hefker. There is no law of distribution.

Explanation #1 (Rashi): [They scatter it] in the place where they put Terumas ha'Deshen.

Objection (and Explanation #2 - Ri): In a Beraisa in Zevachim, R. Chanina ben Antigonus says that there were two places for burning, one to the east of the Mizbe'ach and one to the east of the ramp.

Note: this is not found in Zevachim. It is in Toras Kohanim Parshah 7 Perek 9. All the Hagahos here conform to the Toras Kohanim and Tosfos ha'Rosh.

The one to the east of the ramp, they put there Mora'os ha'Of (the innards) and Dishun (ashes) of the inner Mizbe'ach and the Menorah. This is where Terumas ha'Deshen is done; this is clear there.

The one to the east of the Mizbe'ach, they burned there Pesulei Kodshei Kodoshim. In this place east of the Mizbe'ach, where they burned Kodshei Kodoshim, they used to scatter the Shirayim mentioned here.

Explanation: "Scattering" mentioned here is burning, for the Pesul is due to the owner, and we say in Pesachim (82b) that whenever the Pesul is due to the blood or owner, it becomes Nosar and it goes to Beis ha'Sereifah (where Pasul Kodshim are burned).

Support: The Mishnah in Sotah (20a) says that before her scroll is erased, if she said that she will not drink, her scroll is buried and her Minchah is scattered on Beis ha'Deshen;

You are forced to say that it is burned there, for she is counted among those whose Menachos are burned.

Explanation: All of them died, and only he (the Safek) was left. He does Chalitzah or Yibum;

However, if [the Mes] had another brother, he may not do Yibum, for [perhaps the Safek is not her Yavam, and] she is a Yevamah l'Shuk.

Explanation: This is a mere Asmachta. Obviously, it is not Kidushin!

Note: It is not obvious that she may do Mi'un after she gave birth. Rav holds that there is no Tenai in Nisu'in! Tosfos must hold that the Drashah connotes that it expounds primarily about Kidushin even without Bi'ah, and this is obvious.
