1)

(a) If the Sheli'ach (of Eruv Chatzeros) is placing his *own* fruit, he does not need to inform his co-residents what he is doing.
Why not?

(b) Then why must he inform them of this if the fruit is their's?

(c) In the former case, the Beraisa obligates him to lift up the fruit a Meshahu. How will the Sabi de'Pumbedisa interpret a 'Mashehu'?

(a) Shmuel holds that Shituf Mavu'os requires Zikuy, whilst Eruv Techumin does not.
What is his source for this?

(b) Rav disagrees. In his opinion, Eruv Techumin *does* require Zikuy (in spite of the Mishnah which seems to hold that it does *not*).
What is *his* source?

(c) On the other hand, he holds that Shituf does *not* need Zikuy.
What does he do with our Mishnah, which holds that it *does*, and what is his reason for saying so?

(d) Rebbi Chiya forbade Rebbi Oshaya's daughter to return from the Mikvah (that was outside the Techum), in spite of the Eruv that her mother-in-law had made on her behalf. The Amora'im agree that Rebbi Chiya's strict ruling was based on the fact that she had not been Mezakeh on her behalf when arranging it.
What other motive did the Gemara at first have in mond that may have prompted Rebbi Chiya's stringent ruling?

(a) What is Rav Nachman's conclusion with regard to Zikuy, both by Shituf Mavu'os and Eruv Techumin?

(b) Rav Nachman asked whether Eruv Tavshilin requires Zikuy or not.
Why did he not resolve his Sha'aleh from Shmuel, who explicitly says that it does?

(c) How does Abaye resolve this with Eruv Techumin, where Rav Nachman ruled 'Ein Tzarich Lezakos, despite the fact that he knew that Shmuel ruled 'Tzarich'?

(a) What did Rebbi Zeira rule with regard to that non-Jewish guardian of the weapons who refused to rent his Reshus for an Eruv?

(b) When will the Eruv of a woman be ineffective without her husband's consent?

(c) Shmuel is one of the sources of the above Halachah (in a). What other ruling did Shmuel issue with regard to someone in the courtyard who failed to participate in the Shituf Mavu'os, which proves both of the above statements?

(d) Why is there no proof for Shmuel from the Beraisa 'Kofin Oso La'asos Lechi ve'Koreh le'Mavoy'?

5) Rav Chiya bar Ashi permits wood from an Asheirah to be used as a Lechi, Resh Lakish permits it to be used as a Koreh.
On what grounds does Rav Chiya bar Ashi disagree with Resh Lakish?

6)

(a) 'Nisma'et ha'Ochel, Mosif u'Mezakeh, ve'Ein Tzarich Lehodi'a'.
Why is that?

(b) What is the problem with learning that the Tana is speaking about replacing the missing food with the same kind of food?

(c) How does the Gemara nevertheless establish the Mishnah in this way?

(d) If the Mishnah is speaking about replacing the missing food with a different kind of food, why does the Mishnah specifically refer to a case of 'Nisma'et'?

(a) The Tana of our Mishnah says 'Nisosfu Aleihen, Mosif u'Mezakeh *ve'Tzarich Lehodi'a'*.
In what way does our Tana disagree with Rebbi Yehudah?

(b) Why might we have thought that, in spite of our Mishnah, the Chachamim agree with him, and that the 'Bameh Devarim Amurim' of Rebbi Yehudah (in the Mishnah on 81b, where he makes the distinction between Eruvei Techumin and Eruvei Chatzeros) comes to *explain* their words, rather than to argue with them?

(c) Why in fact, do the Rabbanan disagree with Rebbi Yehudah?

(a) What is the minimum Shiur for Eruvei Chatzeros ...

1. ... by a large family? What constitutes a large family in this regard?
2. ... by a small one?

(b) What does Rebbi Yossi say about an Eruv which diminished?

(a) Rebbi Eliezer appears to permits any food to be used for Eruvei Chatzeros or Shitufei Mavu'os.
What does Rebbi Yehoshua hold?

(b) Does Rebbi Yehoshua require the Eruv to consist of specifically *one* loaf, or can it consist of a number of loaves?
