1)

(a) Beis Shamai invalidates an old Sukah.
What do Beis Hillel say?

(b) What constitutes an old Sukah?

(c) When will even Beis Shamai concede that an old Sukah is Kasher?

(a) How do Beis Shamai learn the Pesul of an old Sukah from the Pasuk in Emor "Chag ha'Sukos ... Shiv'as Yamim la'Hashem"?

(b) Beis Hillel learn from this Pasuk the Derashah of Rav Sheshes quoting Rebbi Akiva?
What does Rav Sheshes say?

(c) How does Rebbi Yehudah ben Beseira learn this from the word "Chag"?

(d) In fact, Beis Shamai too, needs this Pasuk for the Derashah of Rav Sheshes.
How does he then learn the Pesul of Sukah Yeshanah from the Pasuk in Re'ei "Chag ha'Sukos Ta'aseh ... "?

(a) What do Beis Hillel learn from the Pasuk "Chag ha'Sukos Ta'aseh ... "?

(b) And what do Beis Shamai hold concerning the construction of a Sukah on Chol ha'Mo'ed?

(a) Rav Yehudah Amar Rav permits balls of thread to be used as Tzitzis even though the thread was not spun 'Lishemah'.
What does he say about using fringes, loose threads from woven or stitched garments to make into Tzitzis on the garments to which they are already attached?

(b) He learns this from the Pasuk in Ki Seitzei "Gedilim Ta'aseh *Lach*". According to him, why do Beis Hillel not learn from "Chag ha'Sukos Ta'aseh *Lecha*" that a Sukah too, must be constructed 'Lishemah' (i.e. to invalidate a Sukah Yeshanah)?

(c) Why should the Pasuk "Gedilim Ta'aseh *Lach*" not also be needed to disqualify stolen material from being used as Tzitzis?

5)

(a) Is a Sukah Kasher if it is built ...

1. ... underneath a tree?
2. ... underneath another Sukah - according to the Tana Kama?

(b) What does Rebbi Yehudah say about one Sukah above another Sukah?

(a) Why does the Tana of our Mishnah need to say that if someone constructs his Sukah underneath a tree, it is *as if he has constructed it inside his house*? Why does he not just say 'Pasul'?

(b) What do we learn from the Pasuk in Re'ei (with regard to the S'chach) "be'Ospecha, mi'Gornecha u'mi'Yikvecha"?

(c) Under what condition is a Sukah that is built underneath a tree whose sun is more than its shade, Kasher?

(d) What does 'be'she'Chavtan' mean?

(a) Why does the Tana of our Mishnah need to teach us the previous Chidush? Is it not obvious that if there is more shade than sun (as Rava pointed out) and the part that is Pasul is Batel (as Rav Papa explained), the Sukah is Kasher?

(b) But is even that not already contained in a Mishnah later, which teaches us that if one bent a vine, a pumpkin or a kind of creeper over his Sukah, his Sukah is nevertheless valid, provided they let in more sun than shade - and there, just like here, it can only be speaking when he mixed the two together?

(a) Why, by virtue of the plural ("ba'Sukos") does the Pasuk not imply quite the opposite (that one Sukah underneath the other, is Kasher)? [Note: It is not however clear, how we can now use the word "ba'Sukos" to teach us this Chidush, when we have already used it for the number of walls.]

(b) The above Halachah however, is not so clear-cut, since all combinations are possible: Both Sukos are Kasher if the bottom Sukah allows in more sun than shade, and the top one is within twenty Amos from the ground. In which case are both Sukos Pasul?

(a) The bottom Sukah is Kasher and the top one Pasul, if the bottom Sukah casts more shade than sun, and the top one, which allows in more sun than shade, is within twenty Amos of the ground.
Why would the bottom Sukah be Pasul if the S'chach of the top one was higher than twenty Amos from the ground?

(b) In which case is the top Sukah Kasher and the bottom one Pasul?
