1)

(a)How do we reconcile Rebbi Chiya and Rav Ketina with each other and with Rav Huna, who learns 'min ha'Lul ve'Lifenim, Tamei, min ha'Lul ve'Lachutz, Tamei mi'Safek'?

(b)According to Rami bar Shmuel and Rav Yitzchak b'rei de'Rav Yehudah, Rebbi Chiya and Rav Ketina can only be speaking in a case of 'min ha'Lul ve'Lifenim'. Why is that?

(c)Why do we initially think that Rebbi Chiya disagrees with them?

(d)How do we in fact, reconcile them with his opinion?

2)

(a)If, as we maintain, Rami bar Shmuel and Rav Yitzchak b'rei de'Rav Yehudah go after the Chazakah (where the blood is found on the outside of the P'rozdor, as we explained), what are the two sides of the Safek in the latter case (where the blood is found on the roof of the inside of the P'rozdor)? On what grounds ought it to be ...

1. ... Tahor?

2. ... Tamei?

3)

(a)Rebbi Yochanan lists three cases where the Rabbanan follow the majority and give it a Din Vaday. One of them is the current case. To which of the cases in our Mishnah is he referring?

(b)With which of the above opinions does he concur?

4)

(a)The second case, based on a Mishnah in the next Perek, is that of Shilya. What is a Shilya?

(b)The Mishnah there says 'Shilya ba'Bayis, ha'Bayis Tamei'. What are the ramifications of this statement? What is the case?

(c)What is the basis for this ruling?

(d)On what grounds does Rebbi Shimon disagree?

5)

(a)Rebbi Yochanan's third case is based on a Beraisa. What does the Tana there say about a woman who gives birth to a detached hand or foot?

(b)What are the ramifications of this ruling?

(c)What might we otherwise have thought?

(d)Why do we not say that?

6)

(a)We cite a Beraisa which discusses a town with nine butcher-shops that sell Basar Shechutah and one that sells Neveilah. The Beraisa rules that someone who purchased a piece of meat from one of the butcheries and cannot remember from which one he purchased it, 'S'feiko Asur'. Why is that?

(b)In which case does the Tana permit him to eat it?

(c)Why does Rebbi Yochanan not include this case in his list?

7)

(a)We ask the same question from a Beraisa regarding someone who is not sure whether, out of a pile of nine frogs and one Sheretz, he touched a frog (which is Tahor) or the Sheretz. What does the Beraisa rule there if this happened in ...

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

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

(b)And what does he rule if the creature that he touched was separated from the others when he touched it?

(c)So why does Rebbi Yochanan not include this case in his list?

8)

(a)And we query Rebbi Yochanan further from the case of Rebbi Yehoshua ben Levi, who discusses a woman who has a miscarriage whilst crossing a river. What does he rule there (with regard to bringing a Korban and eating it)?

(b)Seeing as this is indeed a case of Tum'as Ishah, why did Rebbi Yochanan not include it in his list?

(c)When Ravin arrived in Bavel from Eretz Yisrael, he cited a Beraisa concerning a woman who erred regarding the date on which she gave birth, and from which Rebbi Yossi b'Rebbi Chanina queried Rebbi Yehoshua ben Levi. What did we initially think Ravin meant when he declared that he failed to understand why there was a problem from there? What Kashya would that then pose on Rebbi Yochanan?

(d)What do we answer? What did Ravin really mean?

9)

(a)What do we suggest Rebbi Yochanan's three cases are coming to preclude? Under which circumstances might a Rov not be considered Vaday (to burn Terumah on account of it)?

(b)On what grounds do we refute this suggestion?

(c)This refutation is based on a Mishnah in Taharos, which discusses a child playing beside a large dough, who is holding a piece of dough in his hand. What is the problem there?

(d)Why then, does Rebbi Meir declare the large dough Tahor?

10)

(a)Why do the Chachamim then declare the large dough Tamei?

(b)According to Resh Lakish, this Chazakah is strong enough to burn T'rumah on account of it. Which Chazakah?

(c)What does Rebbi Yochanan say?

11)

(a)We therefore conclude that Rebbi Yochanan comes to preclude the Rov of Rebbi Yehudah. In the Mishnah in the following Perek, which discusses a woman who miscarries a piece of flesh, where the Tana Kama renders her Tamei only if it is accompanied by blood. Why is she Tamei?

(b)What does Rebbi Yehudah say?

(c)What is the basis of their Machlokes?

12)

(a)How does Rav Yehudah Amar Shmuel qualify Rebbi Yehudah's ruling? Under which circumstances will Rebbi Yehudah concede that she is Tahor?

(b)How does Rebbi Yochanan counter this? In which case will Rebbi Yehudah then argue with the Tana Kama?

13)

(a)What is the basis of the Machlokes between Rebbi Yehudah and the Rabbanan?

(b)What is the Rabbanan's reason?

(c)What does Rebbi Yochanan now come to teach us by confining his initial statement to three cases?
