What determines whether grain is considered chadash and remains forbidden after Pesach?
Halachot 3-4 establish that grain which took root before the omer is permitted once the omer is offered; grain that took root after must wait until the following year's omer, regardless of when it was planted or harvested.
Question 2
For kilai hakerem, who is liable for lashes according to Scriptural Law?
Halachah 6 states that whoever eats an olive-sized portion from kilai hakerem — whether from the vegetables or the grapes, combining both to reach the measure — is liable for lashes by Scriptural Law.
Question 3
What is the status of orlah in the Diaspora according to halachah 9?
Halachah 9 rules that in the Diaspora, the orlah prohibition derives from a halachah l'Moshe miSinai: only certainly-orlah produce is forbidden; where there is doubt, the produce is permitted.
Question 4
How does the Rambam rule regarding neta reva'i (fourth-year produce) in the Diaspora?
Halachah 14 presents the Rambam's ruling that neta reva'i simply does not apply in the Diaspora — not even in Syria where tithes apply Rabbinically — and one may eat fourth-year produce without any redemption. He rejects the Geonic view requiring kerem reva'i redemption.
Question 5
What level of punishment applies to eating tevel from which terumah gedolah has been separated but tithes have not?
Halachah 20 distinguishes: eating tevel before separating terumah gedolah and terumat ma'aser incurs death by Heaven; but once those are separated, eating without separating tithes incurs lashes — not death — since the death penalty attaches specifically to terumah.
