REVIEW QUESTIONS ON GEMARA AND RASHI

prepared by Rabbi Eliezer Chrysler

Previous daf

Shabbos 5

1)

(a) The Gemara then suggests that the author of our Mishnah should be Acheirim (alias Rebbi Meir), who says, that if someone stands still and receives a thrown object, then the thrower is Chayav, but if he has to move from his place in order to catch it, he is Patur. Why is the thrower Patur in the latter case?

(b) Why might the author of our Mishnah now be Rebbi Meir?

(c) The Gemara rejects this contention, too, on the grounds that Acheirim only speak about Hanachah, but not Akirah. Maybe they will agree that Akirah *does* require a Makom Chashuv. On what two grounds does the Gemara reject even the proof from Hanachah?

2) The Gemara then tries to establish our Mishnah in a case where the Ani and the Ba'al ha'Bayis are holding a basket of four by four Tefachim in their hands.
(a) What is the problem with this, with regard to the Ani in the Reshus ha'Rabim? What does Rebbi Yossi b'Rebbi Yehudah say in this regard?

(b) How does the Gemara resolve *this* problem?

(c) Yet this explanation too, is doomed. Why?

3) So we try to say that our Mishnah speaks when the two hands involved were below three Tefachim from the ground.
(a) How will *that* resolve the problem?

(b) But in that case, our Mishnah will have to be speaking when the two men are sitting on the ground. But the Tana specifically writes 'Omed', and not 'Yoshev', the Gemara objects? What are the three ways of answering this Kashya?

(c) However, the Gemara rejects this answer, too. On what grounds?

(d) How does Rava finally resolve the problem of hands being less than four by four?

4) If someone throws an object, which lands by chance in someone's hands, he is Chayav.
(a) What is the Chidush of this statement of Rebbi Yochanan?

(b) Rebbi Yochanan asks whether someone who throws an object, then runs and catches it in mid-air, is Chayav or Patur. Why does the Gemara initially fail to understand what the Sha'aleh is?

(c) What in fact, *is* the Sha'aleh?

5)
(a) Rebbi Yochanan is also quoted as saying that someone who extends his hand from the street into his friend's courtyard and withdraws it holding the rain-water that he caught, is Chayav. What is wrong with that statement?

(b) It doesn't help to say that he caught the rain in mid-flight, because the air is not a Makom Chashuv. So he must have collected it from his friend's wall. What is wrong with *that*, and what is wrong with saying that he collected it from a sloping wall, even if the wall has a ledge where the water gets caught?

(c) How does the Gemara finally establish the case, and what is the Chidush?

6)

(a) What does the Gemara say about someone who is standing on the threshold of his house, when the scroll he is reading slips from his hand and falls onto a sloping wall, and he is left holding one end?

(b) What threshold are we talking about, and why is that?

(c) What will the Din be in the same situation, if he was reading the scroll on the roof overlooking the street (two possibilities) and why?

(d) What will be the Din in the latter case if the scroll remains hanging in mid-air?

7)
(a) If someone picks up a nut floating on the water and carries it outside, will he be Chayav for carrying, and what is the reason for this?

(b) Rava asks what the Din will be if someone takes a cup from a box which is floating on the water.
What are the two sides to Rava's Sha'aleh?

(c) If a Tevul Yom touches Terumah oil which is floating on Terumah wine, the Tana Kama (in a Mishnah in Tevul Yom) holds that the oil only is Tamei, but the wine remains Tahor.
What does Rebbi Yochanan ben Nuri hold in that case, and what is his reason?

(d) What is the Tana Kama's reasoning, and what does Rava learn from this Machlokes with regard to the Melachah of Hotza'ah?

8)
(a) If someone picks up food before Shabbos and proceeds to walk in and out of the house with it - the entire Shabbos, what will he have to do, before becoming Chayav on Shabbos?

(b) What is the difference (regarding Hotza'ah) whether one stops to rest or to adjust one's load?

(c) Abaye learnt this from a statement made by Rabbah.
What did Rabbah say?

(d) The previous Halachah is stated in the name of Rebbi Yochanan. But why did it need to be said, when Rebbi Yochanan has already taught us that someone who is moving objects from one corner to another and, in the middle of transportation, he decides to carry them out of his house, he is Patur, because when he picked them up, it was not with the intention of carrying them out?

9)
(a) If someone carries from a shop to the street via a park area, where there are benches for people to sit, according to the Tana Kama, he is Chayav; Ben Azai says Patur.
What is Ben Azai's reason?

(b) What problem does the Gemara have with the Tana Kama's opinion?
